But I realized when + +32 +00:02:38,599 --> 00:02:43,360 +proofreading the transcripts that it is spelled differently if it's an adjective or a verb. + +33 +00:02:43,560 --> 00:02:44,479 +That's a really good insight. + +34 +00:02:44,500 --> 00:02:48,020 +So I noticed like the misspelling and I was like, but usually I thought it did end with + +35 +00:02:48,020 --> 00:02:52,640 +an E. So this is interesting. We're going to share this today. This is a common error + +36 +00:02:52,640 --> 00:02:57,979 +by native speakers as well. So not something you really need to stress about. But if you can make + +37 +00:02:57,979 --> 00:03:03,680 +this improvement, there will be times where people are impressed. If it's an email or a written memo or + +38 +00:03:03,680 --> 00:03:08,140 +something, especially at work, and you spell this correctly, you're doing better than probably + +39 +00:03:08,139 --> 00:03:10,259 +80% of native English speakers. + +40 +00:03:10,699 --> 00:03:15,199 +Oh, for sure. And I think even beyond just spelling it correctly, just using it is going + +41 +00:03:15,199 --> 00:03:21,739 +to put you probably in the top 25% of native speakers, I think. I don't think this is an + +42 +00:03:21,739 --> 00:03:25,259 +average word. I think this is an above average word to use, Aubrey. Don't you think? + +43 +00:03:25,619 --> 00:03:30,619 +Yes, it's an impressive word. We're going to go into both the verb and the adjective. And we're also + +44 +00:03:30,619 --> 00:03:37,079 +going to share a few more interesting ways to share this because connection isn't just about things you have + +45 +00:03:37,080 --> 00:03:42,580 +in common and things you like. We also connect about things we loathe, things we dread, things we hate. + +46 +00:03:42,980 --> 00:03:45,920 +So this is interesting too. You need to also have this vocab. + +47 +00:03:46,480 --> 00:03:51,740 +Yeah. And it doesn't mean that you're a negative person. If you're always connecting, there can be + +48 +00:03:51,740 --> 00:03:55,740 +very positive connection around something you don't want to do, especially if you share that in + +49 +00:03:55,740 --> 00:03:59,420 +common with someone else. That can be a true connection moment as well. + +50 +00:03:59,860 --> 00:04:05,120 +Yes, for sure. We also want to give a shout out. There was a comment on YouTube + +51 +00:04:05,120 --> 00:04:10,759 +from Rehaman from India. And there wasn't a question, but they just said, I love all your + +52 +00:04:10,759 --> 00:04:15,960 +podcasts. Could you please call out my name in your next podcast? So hello, Rehaman. Thank you + +53 +00:04:15,960 --> 00:04:20,379 +for the YouTube comment. And we wanted to give you a shout out. Wonderful.

Yes. + +57 +00:04:37,680 --> 00:04:42,680 +Awesome. All right. Let's dive in with this interesting vocabulary. So when we use the adjective + +58 +00:04:42,680 --> 00:04:50,920 +loathe, it's always in this chunk loathe to, loathe to do something. And this means to intensely dislike + +59 +00:04:50,920 --> 00:04:56,980 +or hate something. So like at the top of the episode, I'm loathe to swim in our pool. Or you might say, + +60 +00:04:56,980 --> 00:05:01,520 +I'm loathe to go through haunted houses. I really don't like them. This is true for me. + +61 +00:05:01,759 --> 00:05:06,120 +I don't like jump scares. I don't want to be like, that's not fun. Do you like haunted houses? + +62 +00:05:06,120 --> 00:05:11,560 +I'm kind of the same way. I love, opposite word, I love going on ghost tours. + +63 +00:05:12,060 --> 00:05:12,960 +Oh yeah, that I would like. + +64 +00:05:13,400 --> 00:05:17,560 +Yeah. You could be on the sidewalk and you're safe and it's happening in that house, right? It's not + +65 +00:05:17,560 --> 00:05:21,819 +happening to you. It's very different when you're in a haunted house and things are jumping out at you. + +66 +00:05:22,220 --> 00:05:26,720 +Right. I think this is for my brother would do this when I was young. He would jump out from behind a door, + +67 +00:05:26,720 --> 00:05:31,520 +and grab you and scream. And I really hate that now. I'm like, please don't jump scare. + +68 +00:05:31,940 --> 00:05:33,400 +Yeah, no jump scare. I love it. + +69 +00:05:33,920 --> 00:05:38,300 +But what's interesting is loathe this way as an adjective is spelled without an E. It's just + +70 +00:05:38,300 --> 00:05:45,220 +L-O-A-T-H, loathe to do something. So that's tricky. What's another example of using it this way? + +71 +00:05:45,220 --> 00:05:51,320 +So someone's habits, right? They're nocturnal. How awake are they? What are their habits? He has always + +72 +00:05:51,319 --> 00:05:57,599 +been loathe to get up early. Okay. Yes. He's just a nighttime person, not a morning person. + +73 +00:05:58,040 --> 00:06:02,360 +Exactly. Right. And like Lindsay said, this is a little less common, but it is impressive. It's + +74 +00:06:02,360 --> 00:06:06,759 +impressive vocabulary. You will hear it. You definitely can use it, but the spelling's a + +75 +00:06:06,759 --> 00:06:11,379 +little tricky because there's no E there. What about when there is an E, Lindsay? This is when + +76 +00:06:11,379 --> 00:06:15,939 +it's a verb in the sentence. To be honest, this is a good review for me too, right? Remembering + +77 +00:06:15,939 --> 00:06:23,360 +where the E goes. So we put an E at the end in this case, right? L-O-A-T-H-E, and that becomes a + +78 +00:06:23,360 --> 00:06:30,980 +verb. Okay. So for example, I loathe driving in snowy weather. And I think native speakers tend to + +79 +00:06:30,980 --> 00:06:37,500 +punch that loathe too. I agree. That almost would be strange because it's like intense hatred or dread. + +80 +00:06:37,500 --> 00:06:41,199 +So it would be strange to be like, I loathe driving in snowy weather. Yeah. + +81 +00:06:41,980 --> 00:06:44,399 +Emphasize it. I loathe driving in snowy weather. + +82 +00:06:44,759 --> 00:06:49,459 +And it's also one of those kind of full mouth words. You need everything happening. So we really + +83 +00:06:49,459 --> 00:06:55,300 +indulge in saying that word. Okay. I agree. Absolutely. Or maybe she loathes doing homework, + +84 +00:06:55,639 --> 00:06:59,160 +right? This has, it can't be something that you just sort of don't like a little bit. + +85 +00:06:59,279 --> 00:07:01,540 +It really has to be a pretty intense feeling. + +86 +00:07:02,680 --> 00:07:06,620 +Love it. Love it. All right, Aubrey, where to now? What else do we need to know? + +87 +00:07:06,620 --> 00:07:11,540 +Yeah. So just the main thing is that these are pronounced exactly the same. So when you're + +88 +00:07:11,540 --> 00:07:15,639 +speaking, you don't have to worry about this at all. It's like effect and effect that we've talked + +89 +00:07:15,639 --> 00:07:20,819 +about recently. Yes. Doesn't matter when you're speaking, but they are spelled differently. So + +90 +00:07:20,819 --> 00:07:25,180 +when you're writing, if you see the word loathe, you need to take a second. Okay. Is this being used + +91 +00:07:25,180 --> 00:07:31,100 +as an adjective or a verb? And the big pro tip here is if it's loathe to, loathe to do something, + +92 +00:07:31,240 --> 00:07:33,280 +that's when there's no E because it's an adjective. + +93 +00:07:33,279 --> 00:07:36,939 +Hmm. Really good to know. So if we're taking the IELTS exam, for example, + +94 +00:07:37,359 --> 00:07:41,579 +or if we're just writing a business email, we need to know, or even a text message to a friend, + +95 +00:07:41,699 --> 00:07:45,659 +we need to know the difference here. Okay. Absolutely. But let's share some other + +96 +00:07:45,659 --> 00:07:51,199 +interesting options because if you're talking about being upset about something or angry or + +97 +00:07:51,199 --> 00:07:56,399 +something you dread or hate doing, there are so many interesting words to ways to say this, + +98 +00:07:56,459 --> 00:08:02,479 +right? Yes. Yes. I really like the word abhor. Yeah. This is actually even stronger than loathe, + +99 +00:08:02,480 --> 00:08:06,860 +if you can believe it, because loathe is pretty strong. But if you say you abhor something, + +100 +00:08:06,860 --> 00:08:10,960 +that's like the most intense dislike that you can get. + +101 +00:08:11,439 --> 00:08:17,460 +Ooh. Okay. So for example, I abhor small spaces. I'm definitely claustrophobic. Are you + +102 +00:08:17,460 --> 00:08:20,340 +claustrophobic, Aubrey? Do you mind being in an elevator? + +103 +00:08:20,340 --> 00:08:21,520 +I don't think so. What about you? + +104 +00:08:21,920 --> 00:08:25,700 +No, I don't think so. I had an apartment in New York or Tokyo too. + +105 +00:08:25,699 --> 00:08:29,039 +Right. If ever you lived in New York, you can't be claustrophobic. + +106 +00:08:30,079 --> 00:08:33,819 +Basically living in a closet. Yeah, for sure. But if I had to be in an elevator for + +107 +00:08:33,819 --> 00:08:38,600 +hours and hours, then I might start getting claustrophobic. I can imagine the length of + +108 +00:08:38,600 --> 00:08:41,799 +time definitely would affect that. Yeah. Because your mind would start running, + +109 +00:08:42,019 --> 00:08:42,860 +right? That's the key. Absolutely. + +110 +00:08:42,860 --> 00:08:44,379 +Okay. What's another? + +111 +00:08:44,500 --> 00:08:49,680 +Or maybe this is about Michelle. She pours olives. She doesn't even like the smell of them. + +112 +00:08:50,379 --> 00:08:54,500 +I know. I think Michelle doesn't love olives. I love them so much. + +113 +00:08:54,779 --> 00:08:59,820 +And I'm sure a lot of our listeners love. I mean, it's a Mediterranean food. I love olives. I can't + +114 +00:08:59,820 --> 00:09:03,980 +imagine a life without olives or olive oil. I mean, I eat so much olive oil. + +115 +00:09:04,159 --> 00:09:08,080 +I have a feeling Michelle does eat olive oil. I think it's just the taste of like actual olives, + +116 +00:09:08,080 --> 00:09:12,779 +a bowl of green and Kalamata olives, but she is missing out. I love them so much. + +117 +00:09:13,759 --> 00:09:19,480 +So abhor is a good one. And then disdain is good. This is a noun, right? + +118 +00:09:19,700 --> 00:09:23,899 +Well, this is tricky. It exists as a noun and a verb. So let's go over the noun first. So this + +119 +00:09:23,899 --> 00:09:27,980 +is the feeling that something isn't worthy of respect or consideration. So maybe like + +120 +00:09:27,980 --> 00:09:35,000 +she looked at him with disdain. So this is a noun here, right? It's what she's using to look that her + +121 +00:09:35,000 --> 00:09:40,300 +expression has disdain in it. Disdain, like not giving the person a chance, very close-minded, + +122 +00:09:40,299 --> 00:09:42,579 +very negative, right? Absolutely. + +123 +00:09:43,199 --> 00:09:46,979 +Or he's always treated her with disdain. Oh, strange word. + +124 +00:09:47,279 --> 00:09:50,719 +Yes. Yeah, it is kind of a strange word. And it also exists as a verb. They are spelled the + +125 +00:09:50,719 --> 00:09:52,919 +same, luckily, unlike loathe. Good. + +126 +00:09:52,919 --> 00:09:58,139 +So this is like, if you treat someone like they're not worthy of respect, you can use this as a verb. + +127 +00:09:58,620 --> 00:10:05,699 +So the main way I've seen this is if you disdain to answer questions. This is very rare + +128 +00:10:05,699 --> 00:10:10,039 +in English that we use this as a verb. When I saw this in the dictionary, there's a verb and + +129 +00:10:10,039 --> 00:10:14,319 +a noun. I had to think, I'm like, I don't hear that very often. So maybe if someone say like, + +130 +00:10:14,320 --> 00:10:19,820 +I disdained to answer the questions or in present. And this is like, because you dislike the questions + +131 +00:10:19,820 --> 00:10:25,680 +or maybe if it were like on a crime show, be like, she disdained to answer. But this is definitely a + +132 +00:10:25,680 --> 00:10:31,500 +connotation of you are not answering them because you disagree with them. Something like that, + +133 +00:10:31,560 --> 00:10:32,379 +right? Interesting. + +134 +00:10:32,379 --> 00:10:34,879 +You don't respect the questions for whatever reason. + +135 +00:10:35,180 --> 00:10:38,640 +Yeah. I mean, the courtroom idea, I know in a courtroom, well, at least on courtroom dramas, + +136 +00:10:38,639 --> 00:10:43,360 +we hear the word sustained a lot, right? A different word, but maybe in a similar family + +137 +00:10:43,360 --> 00:10:44,519 +sort of thing. I don't know. + +138 +00:10:44,720 --> 00:10:47,799 +Good point. Good point. So this is really interesting too, to think about. + +139 +00:10:48,360 --> 00:10:54,460 +Some of these we use more often in the past tense, right? We wouldn't really use abhor in + +140 +00:10:54,460 --> 00:11:00,319 +the past tense. We're like, I abhorred that film. I loathed that restaurant. Not really, right? + +141 +00:11:00,500 --> 00:11:06,120 +Instead, we usually use these in the present because they're such strong feelings. It's more like, + +142 +00:11:06,120 --> 00:11:11,960 +this is something I always will always abhor or loathe because it's a strong, it's hard to like + +143 +00:11:11,960 --> 00:11:17,320 +hate something that strongly that just happened once, like one trip to a restaurant or something, + +144 +00:11:17,460 --> 00:11:20,820 +right? I see what you're saying. So it's almost like a state of being, this feeling. + +145 +00:11:20,820 --> 00:11:22,360 +Yes. Almost like state of being. + +146 +00:11:22,360 --> 00:11:26,000 +Exactly. That's how strong it is, right? If it's something we don't like, we probably would say + +147 +00:11:26,000 --> 00:11:32,820 +like, oh, I really hated that. I absolutely detested it. Or I would say, I couldn't stand it. + +148 +00:11:33,019 --> 00:11:33,279 +Yes. + +149 +00:11:33,340 --> 00:11:35,419 +I mean, I really didn't like it. + +150 +00:11:35,419 --> 00:11:39,819 +Yes. I love that. That's a really important point. So it's the things that we really hate + +151 +00:11:39,819 --> 00:11:46,819 +and we've always hated. We just don't identify with those things. We're using abhor or loathe, + +152 +00:11:47,519 --> 00:11:53,000 +whereas it's a single experience or a movie or a meal, lighter things like hate. I mean, + +153 +00:11:53,059 --> 00:11:57,939 +light is not, hate is not light, but like we don't get that passionate about like an individual + +154 +00:11:57,939 --> 00:12:03,360 +experience, right? So these words, this is what's important to, to pay attention to here is + +155 +00:12:03,360 --> 00:12:09,940 +these words really signify that a passionate dislike. And so it is strange if you use them. + +156 +00:12:10,080 --> 00:12:14,379 +We don't even really use them jokingly to talk about how much we dislike something. I guess you + +157 +00:12:14,379 --> 00:12:21,120 +could be like, oh, I loathe spinach. And you're just joking, right? But for the most part, it's for + +158 +00:12:21,120 --> 00:12:24,039 +things that you really hate, feel very strongly about. + +159 +00:12:24,039 --> 00:12:30,019 +All right. Good to know. Excellent. Okay, Aubrey, we are back from break. Let's do a role play for + +160 +00:12:30,019 --> 00:12:35,059 +today. Here we are discussing the foods that we dislike. Okay. Let's see. + +161 +00:12:35,059 --> 00:12:39,980 +I'll start us out. I'm not usually picky, but I absolutely abhor eel. + +162 +00:12:40,559 --> 00:12:45,120 +Really? I love eel rolls at a sushi place. Eel sauce is delicious. + +163 +00:12:45,120 --> 00:12:51,120 +Yeah. It's not for me. I'm loathe to even think about eating eel. What about you? Are there any + +164 +00:12:51,120 --> 00:12:56,560 +foods that you can't stand? Hmm. Yeah. I've always had disdain for masago. + +165 +00:12:57,060 --> 00:13:02,039 +Oh, that's fish eggs, right? Yeah. I don't know what it is, but I loathe it. + +166 +00:13:02,440 --> 00:13:08,120 +Okay. Nice. So this is possible that you like really dislike certain foods and we would use, + +167 +00:13:08,179 --> 00:13:12,740 +you know, abhor, loathe, whatever. But if you just mean to say like, I don't really like that very much, + +168 +00:13:12,740 --> 00:13:17,519 +we wouldn't use these bigger, stronger words. I think a lot of people have issues around texture, + +169 +00:13:17,799 --> 00:13:21,159 +right? The texture of things. Even some people don't like the texture of eggs, + +170 +00:13:21,860 --> 00:13:25,500 +but sort of fish eggs, the texture, I think people probably struggle with. + +171 +00:13:25,680 --> 00:13:29,820 +That's why I like eel, but I know someone who doesn't and I think it's a texture thing. + +172 +00:13:30,279 --> 00:13:34,680 +Yeah. No, eel is great. When I lived in Japan for my last meal there, my friends, + +173 +00:13:34,759 --> 00:13:39,720 +my Japanese friends took me to an eel restaurant, a place like in the mountains that specialized just in + +174 +00:13:39,720 --> 00:13:45,180 +eel. It was amazing. Wow. That's awesome. And I do love eel sauce. This is me. I think it's so + +175 +00:13:45,180 --> 00:13:50,300 +tasty. It's a little bit sweeter on some rolls. Oh, so delicious. Yes, exactly. Let's go through + +176 +00:13:50,300 --> 00:13:56,379 +this. So again, you said, I'm usually not picky, but I absolutely abhor eel. It's kind of a weird + +177 +00:13:56,379 --> 00:14:00,720 +word too, because we are kind of pronouncing the H, aren't we, Aubrey? Yes, we do have to, + +178 +00:14:00,820 --> 00:14:05,160 +right? You hit that H kind of hard, abhor. And this is another one where you have to like + +179 +00:14:05,159 --> 00:14:09,639 +hit the word hard. You have to emphasize it just like loathe. It's a little strange. We're like, + +180 +00:14:09,679 --> 00:14:14,819 +I really abhor that. No, you need the intonation needs to be powerful because the emotion, + +181 +00:14:15,000 --> 00:14:18,579 +the passion about the dislike is powerful. The word implies that. + +182 +00:14:19,019 --> 00:14:21,980 +Yeah. We don't want to have that flat affect, right? We want to make sure we're + +183 +00:14:21,980 --> 00:14:24,659 +putting life into our words here. What else, Aubrey? + +184 +00:14:24,899 --> 00:14:30,199 +Yeah. And then I said, oh, it's not for me. I'm loathe to even think about eating eel. So this is where + +185 +00:14:30,200 --> 00:14:35,740 +it's an adjective. I'm describing myself, myself as loathe to think about something. + +186 +00:14:36,259 --> 00:14:38,740 +Hmm. Very interesting construction too. I'm loathe to even think. + +187 +00:14:38,740 --> 00:14:40,879 +Yeah. So it would be written without the E there, right? + +188 +00:14:40,920 --> 00:14:47,620 +Okay. No E there. Good. And then I said, hmm, yeah, I've always had disdain for masago. + +189 +00:14:48,080 --> 00:14:52,000 +Hmm. Yeah. Since I've always, and this is an interesting thing to say, like disdain, + +190 +00:14:52,000 --> 00:14:58,800 +because it does often imply more of like a lack of respect. So this would be sort of joking even to + +191 +00:14:58,799 --> 00:15:03,559 +say this about food. Be like, oh, I have such disdain for masago. Like I would probably laugh + +192 +00:15:03,559 --> 00:15:08,819 +at that. I'd be like, that's really funny because it usually does imply more like, um, + +193 +00:15:09,199 --> 00:15:14,419 +you, you, you are critical of something. You, you disrespect something. + +194 +00:15:15,120 --> 00:15:19,019 +Right. For bigger things than just food. Like food is just a taste. That's all it is. It's + +195 +00:15:19,019 --> 00:15:25,019 +sort of one dimensional. Right. But for example, like political parties or certain ways of thinking + +196 +00:15:25,019 --> 00:15:29,139 +would be more common for disdain, right? That's where you would use it more literally, + +197 +00:15:29,340 --> 00:15:33,340 +right? This is kind of more joking, but yeah, you could say you have disdain for a certain + +198 +00:15:33,340 --> 00:15:37,899 +political candidate or people who agree with a certain policy. That would be more because it's + +199 +00:15:37,899 --> 00:15:42,699 +more of a lack of respect for that for sure. And then the last thing that was said was, yeah, + +200 +00:15:42,699 --> 00:15:48,600 +I don't know what it is, but I loathe it. Right. So they just mean like, I really hate it. Yeah. + +201 +00:15:48,600 --> 00:15:54,300 +And this is because it's a verb. This would be spelled with an E L O A T H E. All right. Good + +202 +00:15:54,300 --> 00:16:00,200 +high level episode for our listeners today at the B2 C1 level. I love it. Yes, absolutely. We want to + +203 +00:16:00,200 --> 00:16:06,060 +make sure that you don't miss the episode that inspired this and 2402 right here on All There's + +204 +00:16:06,060 --> 00:16:11,600 +English. Should you call someone cheap in English where we said sometimes people are loathe to spend + +205 +00:16:11,600 --> 00:16:17,019 +money. So use it as an adjective there. So it wouldn't have an E. Yes. And the connection piece + +206 +00:16:17,019 --> 00:16:22,079 +here guys for today is it's not always, it doesn't have to be about these positive, amazing things + +207 +00:16:22,079 --> 00:16:27,500 +that you're connecting over. You can build just as strong of a connection over things that you loathe + +208 +00:16:27,500 --> 00:16:33,079 +and have disdain for. Okay. Absolutely. Yes. Right. I feel like that would even bond you closer with + +209 +00:16:33,079 --> 00:16:38,279 +someone if you are sort of willing to admit these more negative things. I don't love everything, + +210 +00:16:38,399 --> 00:16:42,699 +right? The people I'm close to, I want to build a stronger connection with. I'm going to admit the things + +211 +00:16:42,700 --> 00:16:47,820 +that I really abhor. Especially if it's very, like most people love this thing, but you actually + +212 +00:16:47,820 --> 00:16:53,080 +have disdain for it, right? Yeah. A hot take. Yes, exactly. That could build a really strong sense + +213 +00:16:53,080 --> 00:16:57,740 +of trust and connection right there. So that's what we're going for. All right.

Don't be loathe to speak English. Welcome to the All Ears English Podcast, downloaded more than 200 million times. Are you feeling stuck with your English? We'll show you how to become fearless and fluent by focusing on connection, not perfection, with your American host, Aubrey Carter, the IELTS whiz, and Lindsay McMahon, the English adventurer, coming to you from Arizona and Colorado, USA. Reach the top 25% of all native speakers by understanding these three ways to say that you dislike something in English. Do you ever wish that you could just hang out with native speakers and pick up real English naturally? That's what it's like here on All Ears English. We're two friends having real conversations, no scripts, no lectures, just fun, honest talk about life, culture, and how to connect in English. It's like grabbing coffee with us and leaving with better English every time. But if you're not following All Ears English, then you're probably missing some episodes. So go ahead and hit the follow button now, wherever you listen to the show. Hit follow now and come check us out five days a week. Hey there, Aubrey, what's shaking? Not much. How are you, Lindsay? Feeling great today, but I have a key question for you today. You ready? Yeah, let's hear it. So Aubrey, in your daily life or just maybe right now in this moment, is there anything you are loathe to do? You know, I am loathe to swim with my kids right now. Our pool is still ice cold, in my opinion. It's way too cold and they are ready to swim. They're getting in. They're like, mom, come swim with me. And it's way too cold for me. So I make excuses and I really, I'm like, I'll just dip my toes in. It's crazy. So I am really loathe to get in that cold swimming pool. It's funny how we lose our nerves as we get older. It becomes harder and harder to get into swimming pools or cold lakes or the ocean. When we're kids, we just run in like, we didn't mind at all. I know. Maybe our nerve endings are less sensitive when we're younger. I don't know. We just don't care. We just don't care. I don't know. We don't think about it. I don't know. We think a lot as adults, don't we? Yeah, for sure. Well, this is interesting. This word loathe came up in a recent episode. Stay to the end and we'll share which one it is in case you missed it. But I realized when proofreading the transcripts that it is spelled differently if it's an adjective or a verb. That's a really good insight. So I noticed like the misspelling and I was like, but usually I thought it did end with an E. So this is interesting. We're going to share this today. This is a common error by native speakers as well. So not something you really need to stress about. But if you can make this improvement, there will be times where people are impressed. If it's an email or a written memo or something, especially at work, and you spell this correctly, you're doing better than probably 80% of native English speakers. Oh, for sure. And I think even beyond just spelling it correctly, just using it is going to put you probably in the top 25% of native speakers, I think. I don't think this is an average word. I think this is an above average word to use, Aubrey. Don't you think? Yes, it's an impressive word. We're going to go into both the verb and the adjective. And we're also going to share a few more interesting ways to share this because connection isn't just about things you have in common and things you like. We also connect about things we loathe, things we dread, things we hate. So this is interesting too. You need to also have this vocab. Yeah. And it doesn't mean that you're a negative person. If you're always connecting, there can be very positive connection around something you don't want to do, especially if you share that in common with someone else. That can be a true connection moment as well. Yes, for sure. We also want to give a shout out. There was a comment on YouTube from Rehaman from India. And there wasn't a question, but they just said, I love all your podcasts. Could you please call out my name in your next podcast? So hello, Rehaman. Thank you for the YouTube comment. And we wanted to give you a shout out. Wonderful. And guys, don't forget to go ahead and hit that follow button wherever you're listening.

So you make sure you get all there's English five days a week. Okay. Yes. Awesome. All right. Let's dive in with this interesting vocabulary. So when we use the adjective loathe, it's always in this chunk loathe to, loathe to do something. And this means to intensely dislike or hate something. So like at the top of the episode, I'm loathe to swim in our pool. Or you might say, I'm loathe to go through haunted houses. I really don't like them. This is true for me. I don't like jump scares. I don't want to be like, that's not fun. Do you like haunted houses? I'm kind of the same way. I love, opposite word, I love going on ghost tours. Oh yeah, that I would like. Yeah. You could be on the sidewalk and you're safe and it's happening in that house, right? It's not happening to you. It's very different when you're in a haunted house and things are jumping out at you. Right. I think this is for my brother would do this when I was young. He would jump out from behind a door, and grab you and scream. And I really hate that now. I'm like, please don't jump scare. Yeah, no jump scare. I love it. But what's interesting is loathe this way as an adjective is spelled without an E. It's just L-O-A-T-H, loathe to do something. So that's tricky. What's another example of using it this way? So someone's habits, right? They're nocturnal. How awake are they? What are their habits? He has always been loathe to get up early. Okay. Yes. He's just a nighttime person, not a morning person. Exactly. Right. And like Lindsay said, this is a little less common, but it is impressive. It's impressive vocabulary. You will hear it. You definitely can use it, but the spelling's a little tricky because there's no E there. What about when there is an E, Lindsay? This is when it's a verb in the sentence. To be honest, this is a good review for me too, right? Remembering where the E goes. So we put an E at the end in this case, right? L-O-A-T-H-E, and that becomes a verb. Okay. So for example, I loathe driving in snowy weather. And I think native speakers tend to punch that loathe too. I agree. That almost would be strange because it's like intense hatred or dread. So it would be strange to be like, I loathe driving in snowy weather. Yeah. Emphasize it. I loathe driving in snowy weather. And it's also one of those kind of full mouth words. You need everything happening. So we really indulge in saying that word. Okay. I agree. Absolutely. Or maybe she loathes doing homework, right? This has, it can't be something that you just sort of don't like a little bit. It really has to be a pretty intense feeling. Love it. Love it. All right, Aubrey, where to now? What else do we need to know? Yeah. So just the main thing is that these are pronounced exactly the same. So when you're speaking, you don't have to worry about this at all. It's like effect and effect that we've talked about recently. Yes. Doesn't matter when you're speaking, but they are spelled differently. So when you're writing, if you see the word loathe, you need to take a second. Okay. Is this being used as an adjective or a verb? And the big pro tip here is if it's loathe to, loathe to do something, that's when there's no E because it's an adjective. Hmm. Really good to know. So if we're taking the IELTS exam, for example, or if we're just writing a business email, we need to know, or even a text message to a friend, we need to know the difference here. Okay. Absolutely. But let's share some other interesting options because if you're talking about being upset about something or angry or something you dread or hate doing, there are so many interesting words to ways to say this, right? Yes. Yes. I really like the word abhor. Yeah. This is actually even stronger than loathe, if you can believe it, because loathe is pretty strong. But if you say you abhor something, that's like the most intense dislike that you can get. Ooh. Okay. So for example, I abhor small spaces. I'm definitely claustrophobic. Are you claustrophobic, Aubrey? Do you mind being in an elevator? I don't think so. What about you? No, I don't think so. I had an apartment in New York or Tokyo too. Right. If ever you lived in New York, you can't be claustrophobic. Basically living in a closet. Yeah, for sure. But if I had to be in an elevator for hours and hours, then I might start getting claustrophobic. I can imagine the length of time definitely would affect that. Yeah. Because your mind would start running, right? That's the key. Absolutely. Okay. What's another? Or maybe this is about Michelle. She pours olives. She doesn't even like the smell of them. I know. I think Michelle doesn't love olives. I love them so much. And I'm sure a lot of our listeners love. I mean, it's a Mediterranean food. I love olives. I can't imagine a life without olives or olive oil. I mean, I eat so much olive oil. I have a feeling Michelle does eat olive oil. I think it's just the taste of like actual olives, a bowl of green and Kalamata olives, but she is missing out. I love them so much. So abhor is a good one. And then disdain is good. This is a noun, right? Well, this is tricky. It exists as a noun and a verb. So let's go over the noun first. So this is the feeling that something isn't worthy of respect or consideration. So maybe like she looked at him with disdain. So this is a noun here, right? It's what she's using to look that her expression has disdain in it. Disdain, like not giving the person a chance, very close-minded, very negative, right? Absolutely. Or he's always treated her with disdain. Oh, strange word. Yes. Yeah, it is kind of a strange word. And it also exists as a verb. They are spelled the same, luckily, unlike loathe. Good. So this is like, if you treat someone like they're not worthy of respect, you can use this as a verb. So the main way I've seen this is if you disdain to answer questions. This is very rare in English that we use this as a verb. When I saw this in the dictionary, there's a verb and a noun. I had to think, I'm like, I don't hear that very often. So maybe if someone say like, I disdained to answer the questions or in present. And this is like, because you dislike the questions or maybe if it were like on a crime show, be like, she disdained to answer. But this is definitely a connotation of you are not answering them because you disagree with them. Something like that, right? Interesting. You don't respect the questions for whatever reason. Yeah. I mean, the courtroom idea, I know in a courtroom, well, at least on courtroom dramas, we hear the word sustained a lot, right? A different word, but maybe in a similar family sort of thing. I don't know. Good point. Good point. So this is really interesting too, to think about. Some of these we use more often in the past tense, right? We wouldn't really use abhor in the past tense. We're like, I abhorred that film. I loathed that restaurant. Not really, right? Instead, we usually use these in the present because they're such strong feelings. It's more like, this is something I always will always abhor or loathe because it's a strong, it's hard to like hate something that strongly that just happened once, like one trip to a restaurant or something, right? I see what you're saying. So it's almost like a state of being, this feeling. Yes. Almost like state of being. Exactly. That's how strong it is, right? If it's something we don't like, we probably would say like, oh, I really hated that. I absolutely detested it. Or I would say, I couldn't stand it. Yes. I mean, I really didn't like it. Yes. I love that. That's a really important point. So it's the things that we really hate and we've always hated. We just don't identify with those things. We're using abhor or loathe, whereas it's a single experience or a movie or a meal, lighter things like hate. I mean, light is not, hate is not light, but like we don't get that passionate about like an individual experience, right? So these words, this is what's important to, to pay attention to here is these words really signify that a passionate dislike. And so it is strange if you use them. We don't even really use them jokingly to talk about how much we dislike something. I guess you could be like, oh, I loathe spinach. And you're just joking, right? But for the most part, it's for things that you really hate, feel very strongly about. All right. Good to know. Excellent. Okay, Aubrey, we are back from break. Let's do a role play for today. Here we are discussing the foods that we dislike. Okay. Let's see. I'll start us out. I'm not usually picky, but I absolutely abhor eel. Really? I love eel rolls at a sushi place. Eel sauce is delicious. Yeah. It's not for me. I'm loathe to even think about eating eel. What about you? Are there any foods that you can't stand? Hmm. Yeah. I've always had disdain for masago. Oh, that's fish eggs, right? Yeah. I don't know what it is, but I loathe it. Okay. Nice. So this is possible that you like really dislike certain foods and we would use, you know, abhor, loathe, whatever. But if you just mean to say like, I don't really like that very much, we wouldn't use these bigger, stronger words. I think a lot of people have issues around texture, right? The texture of things. Even some people don't like the texture of eggs, but sort of fish eggs, the texture, I think people probably struggle with. That's why I like eel, but I know someone who doesn't and I think it's a texture thing. Yeah. No, eel is great. When I lived in Japan for my last meal there, my friends, my Japanese friends took me to an eel restaurant, a place like in the mountains that specialized just in eel. It was amazing. Wow. That's awesome. And I do love eel sauce. This is me. I think it's so tasty. It's a little bit sweeter on some rolls. Oh, so delicious. Yes, exactly. Let's go through this. So again, you said, I'm usually not picky, but I absolutely abhor eel. It's kind of a weird word too, because we are kind of pronouncing the H, aren't we, Aubrey? Yes, we do have to, right? You hit that H kind of hard, abhor. And this is another one where you have to like hit the word hard. You have to emphasize it just like loathe. It's a little strange. We're like, I really abhor that. No, you need the intonation needs to be powerful because the emotion, the passion about the dislike is powerful. The word implies that. Yeah. We don't want to have that flat affect, right? We want to make sure we're putting life into our words here. What else, Aubrey? Yeah. And then I said, oh, it's not for me. I'm loathe to even think about eating eel. So this is where it's an adjective. I'm describing myself, myself as loathe to think about something. Hmm. Very interesting construction too. I'm loathe to even think. Yeah. So it would be written without the E there, right? Okay. No E there. Good. And then I said, hmm, yeah, I've always had disdain for masago. Hmm. Yeah. Since I've always, and this is an interesting thing to say, like disdain, because it does often imply more of like a lack of respect. So this would be sort of joking even to say this about food. Be like, oh, I have such disdain for masago. Like I would probably laugh at that. I'd be like, that's really funny because it usually does imply more like, um, you, you, you are critical of something. You, you disrespect something. Right. For bigger things than just food. Like food is just a taste. That's all it is. It's sort of one dimensional. Right. But for example, like political parties or certain ways of thinking would be more common for disdain, right? That's where you would use it more literally, right? This is kind of more joking, but yeah, you could say you have disdain for a certain political candidate or people who agree with a certain policy. That would be more because it's more of a lack of respect for that for sure. And then the last thing that was said was, yeah, I don't know what it is, but I loathe it. Right. So they just mean like, I really hate it. Yeah. And this is because it's a verb. This would be spelled with an E L O A T H E. All right. Good high level episode for our listeners today at the B2 C1 level. I love it. Yes, absolutely. We want to make sure that you don't miss the episode that inspired this and 2402 right here on All There's English. Should you call someone cheap in English where we said sometimes people are loathe to spend money. So use it as an adjective there. So it wouldn't have an E. Yes. And the connection piece here guys for today is it's not always, it doesn't have to be about these positive, amazing things that you're connecting over. You can build just as strong of a connection over things that you loathe and have disdain for. Okay. Absolutely. Yes. Right. I feel like that would even bond you closer with someone if you are sort of willing to admit these more negative things. I don't love everything, right? The people I'm close to, I want to build a stronger connection with. I'm going to admit the things that I really abhor. Especially if it's very, like most people love this thing, but you actually have disdain for it, right? Yeah. A hot take. Yes, exactly. That could build a really strong sense of trust and connection right there. So that's what we're going for. All right. Good stuff, Aubrey. We'll see you in the next episode of All There's English and guys hit the follow button now. Yes. Awesome. We'll see you guys next time. All right. Take care. Bye. Bye. Bye.

Face社区获得了169个点赞显示出其研究价值和社区的关注度这篇论文的核心目标是提升大型语言模型LMS的性能通过一种名为反思重视奖励的新框架来实现这个框架的关键在于让模型在任务失败后进行自我反思分析失败原因并在再次尝试时利用这些反思来改进表现具体来说模型在失败后会生成一段自我反思的评论解释哪里出了问题并提出改进建议然后模型会根据这些反思再次尝试任务如果第二次尝试成功模型在反思阶段生成的内容会通过一种名为Group Relative Policy OptimizationGruple的算法获得奖励从而进一步优化其自我反思的能力论文中使用了多个模型进行实验包括CornarLama 3.1Fi 3.5Mini Instruct等并基于两个主要数据集Epojin和CountdownEpojin数据集包含6万个高质量的函数调用要求模型生成正确的工具调用Countdown数据集则包含45万个数字列表和目标数字要求模型通过这些数字生成正确的方程来达到目标研究结果显示这种反思重视奖励的方法在提升模型性能方面非常有效特别是在Epojin数据集上经过Gurple训练的Quin27B模型甚至超过了未经过训练的Quin272B模型此外自我反思显著提升了模型在Countdown数据集上的表现尤其是对于那些初始表现较差的模型论文还指出这种自我反思的方法不仅增强了模型解决复杂任务的能力还使得较小的模型能够超越较大的未训练模型显示出其在效率和通用性上的优势此外研究中几乎没有观察到灾难性遗忘的现象表明这种方法在模型乳棒性方面也有显著提升总的来说这篇论文提出了一种创新的方法通过强化学习的方式让LLMS进行自我反思和改进从而在复杂任务上取得更好的表现这是本期节目的第二篇论文题目是超越8020法则高商少数Token驱动LLM推理的有效强化学习这篇论文目前在Hugging Face社区获得了130个点赞显示出它在学术界引起了广泛关注这篇论文的核心研究问题是在大型语言模型LLMS的验证奖励强化学习RLVR中不同类型的Token如何影响推理性能以及是否可以通过专注于特定类型的Token来提升RLVR的效果研究团队提出了一个假设高商的少数Token作为推理路径中的关键分支点比低商的多数Token更能有效驱动RLVR他们进一步假设通过限制策略梯度更新到这些高商Token可以在保持或提升性能的同时提供计算上的优势为了验证这一假设研究团队进行了详细的实验设计他们选择了捆3LLM家族的8B 14B和32B基础模型作为研究对象通过链式思维COT推理中的Token商模式分析结合控制实验来调节这根商并在RLVR训练中选择性的更新策略梯度数据收集方面他们使用了M24 M25等数据集并在多个评估数据集上进行了验证实验结果显示高商Token在推理过程中起到了关键作用他们不仅连接了逻辑推理的各个环节还能通过调节节码温度来显著影响模型的性能具体来说降低高商Token的温度会降低性能而增加其温度则能提升性能此外RLVR在训练过程中保留了基础模型的商模式并且主要改变了高商Token的商值最令人振奋的是研究团队发现仅关注高商Token的策略梯度更新不仅没有降低性能反而在Koen3模型上显著提升了推理效果这一发现对于优化LM的推理能力具有重要意义尤其是在处理复杂推理任务时高商Token的聚焦策略能够平衡探索与训练稳定性为模型带来更大的性能提升总的来说这篇论文通过深入分析Token商对推理性能的影响揭示了高商少数Token在驱动LM推理中的关键作用为未来的LMU化提供了新的思路和方法这是本期节目的第三篇论文题目是Po延长的强化学习拓展大型语言模型的推理边界这篇论文目前在Hugging Face社区获得了115个点赞显示出它在研究社区中引起了广泛关注这篇论文的核心研究问题是延长的强化学习训练能否在大型语言模型中揭示出新的推理策略这些策略是基础模型在广泛采样下也无法获得的研究团队提出了一个假设通过延长的强化学习训练模型可以在其基础模型的基础上拓展推理能力发现新的解决方案路径并在各种任务中表现更好为了验证这一假设研究团队设计了一种名为Pro的新训练方法这种方法结合了KL散度控制参考策略重置以及一系列多样化的任务他们使用了三个模型进行实验DeepSea Car 1-15B作为基础模型Demitra Research Reasoning宽1.5B作为经过Pro训练的模型以及DeepSea Car 1-7B用于比较在实验过程中Pro训练包括了超过2000步的强化学习训练同时引入了KL散度惩罚来保持伤并防止策略漂移参考策略会定期重置以允许持续改进训练数据涵盖了数学代码STEM逻辑谜题和指令跟随等多种任务共构建了一个包含136000个视力的多样化训练数据集研究结果显示经过强化学习训练的模型在各种任务中的表现显著优于基础模型例如在数学任务中PiSide1的提升达到了14.7%在编码任务中提升了13.9%在逻辑谜题中提升了54.8%在STEM推理任务中提升了25.1%在指令跟随任务中提升了18.1%此外研究还发现Pro训练在超过2000步后仍能持续提升模型性能论文还引入了创造力指数来量化推理路径的吸引性结果表明延长的强化学习训练确实能够产生更具创新性的解决方案这一发现挑战了之前认为强化学习模型不会获得新推理能力的研究结论总的来说这篇论文提供了新的见解展示了在什么条件下强化学习能够有效拓展语言模型的推理边界研究结果表明通过稳定且延长的强化学习训练开发出超越基础模型初始能力的新的推理模式本期节目的第四篇论文我们来关注一篇名为Alpha 1测试时驱动大模型进行快慢思考的推理框架的研究这篇论文目前在Hugging Face社区获得了89个点赞显示出它在学术界和开发者社区中的广泛关注这篇论文的核心目标是解决大型推理模型LRMS在测试时如何动态调节推理过程的挑战研究人员提出了一个名为Alpha 1Alpha 1的框架旨在提升LRMS的推理能力和效率简单来说Alpha

L40S和A100GPU上进行确保了计算资源的充足和实验的可靠性论文的主要创新点在于引入了Alpha时刻AlphaMoment这一概念通过于Alpha和后Alpha时刻的调节Alpha1能够有效地在测试时对LRMS进行缩放研究人员还通过对比实验验证了Alpha1在问题解决准确性PiCity和推理效率FAP指标上的显著提升例如1.5B的模型在使用Alpha1后问题解决准确性提高了6.15%同时令牌长度减少了14%研究结果显示Alpha1不仅在准确性上超越了传统的测试时缩放方法如SE和Chain of Draft而且在推理效率上也表现出色特别是论文发现慢思考到快思考的线性调度方式能够带来最高的推理准确性这表明慢思考在提升推理效率方面起到了关键作用总体而言Alpha1为大型推理模型提供了一个通用的推理过程调节框架展示了慢思考和快思考的动态转换如何有效提升模型的推理能力这一研究不仅为LRMS的实际应用提供了新的思路也为未来在测试时优化模型推理提供了宝贵的经验这就是本期节目关于Alpha1测试时驱动大模型进行快慢思考的推理框架的介绍这是本期节目的第五篇论文题目是Small
