Today we're going to talk about 10 useful prefixes. Prefix, by the way, is like a small word. A few letters that we attached to the beginning of a word to change the meaning of that word. Let's go re the first prefix is re re r e re means again. So we see the word rien like redo or replay or re imagine or recreate, for example. So it means to do the base word again. So whatever you see Ri in front of, um or not everything. But if you see re before a base word like that, it can mean to do that thing again. So in a sentence, I have to redo my homework. Okay, Aunty, the next prefix is anti anti or you might hear anti as well, Auntie or anti. Both are fine, but it means against or in opposition to, or like, kind of the opposite of something. So against against anti. So we see this in like, um, antifreeze or anti social or ah anti inflammatory or antibiotics so they all mean against something. Um, so like the word antifreeze, for example, means like against freezing. So it's a it's antifreeze is a product that prevents a liquid from freezing. For example, an antibiotic is a medicine that we take to kill like bad microorganisms in our body germs, in other words, so we see bio in that word, so relating to like biology. Ah, antisocial refers to someone who does not like social situations. They're against social situations, an anti inflammatory. Another type of medicine is against inflammation, so inflammation can mean like swelling or like turning you read, for example, so anti means against something. We see anti before words which mean, like opposing or against that thing in a sentence. My boss is anti overtime. This so the next prefix is this this so dis? Essentially, this means not so we see this in words like disrespect or disapprove or disconnect or like disagree, for example. So these weren't all mean, not plus the base words, so like disagree, for example, means to not agree or disconnect means to not connect, so something is not connected to the other thing. Disrespect means to not respect something, for example, so this means not plus that based word in a sentence. A good editor should be dis interested. X. The next prefix is x x x means former former So something that was once true is not true anymore. We see this very commonly in relationships. So, for example, my ex husband, ex wife, ex girlfriend, ex boyfriend, ex boss. So all of these mean my former something. My former boyfriend, my former girlfriend, my former boss, my former roommate, for example. In a sentence, the ex CEO was in the news this week mid. The next prefix is mid, mid, so mid means, like in the middle of or during something. So we can see this in a word like, uh, midnight or mid summer, for example, or mid morning. So meaning in the middle of or roughly in the middle of something during that time period. Mid night means in the middle of the night or mid morning. It's like in the middle of the morning. So all of these refer to admit to something we can also use it for, like an action like mid meal, for example, or she was mid presentation when the phone rang, for example, so mid means in the middle of something in a sentence. I was mid breakfast when I heard the news ill. The next one is ill, ill. So ill means again not, or it's like a negative prefix. It means, Ah, the base word, but not that base word. So we see this in words like illogical or illegible or illegal, for example, So he's all mean, not plus the base words. So illogical means not logical. Ill, legible, illegible means unable to religion. Ble means readable, illegible means cannot read that thing. Unable to read that illegal means not legal, in other words, so an action that is against the law so ill means not in a sentence. Highly illogical Captain, that's a Star Trek reference in the next prefix is in. In I Am in also means not. It means not words that fit. This pattern, for example, could be impossible or impeccable or improbable or imperfectly, for example. So again, it means not so imperfectly means not perfect, uh, impossible means not possible. S o. M means not. It means not in a sentence. This is impossible. In the next prefix is in in so again in also means not. It's a negative prefix that we use. There are a lot of words that start with this in meaning. Not so like inconsiderate, incapable, inconceivable um inappropriate. So they all mean not plus the base word, for example, like the word in appropriate means not appropriate. So behavior that is not appropriate in a certain situation or incapable means not capable. Someone cannot do something. They're expected to d'oh. So in means not, plus our base needing the opposite. Then up that meeting in a sentence he's incapable of running the country here. The next prefix is ear ear. So the pronunciation is here even though it's I are here, for example, we see this in, like, irresponsible or irredeemable or irregular. So again, this means not something so irresponsible means not responsible, irregular, not regular. You're redeemable is something that cannot be made up. We cannot redeem that thing. So here is another negative prefix meaning not or no in a sentence. Your behavior was irresponsible. None. The next prefix is non non an o n. So N o. N is a prefix again. It means not or against her like Russian Sagan's So non also means not something. Ah, so, for example, we see it in a word like nonsense or like non sequential or non sequitur. So these are words that all mean, like not something. So, for example, non sense means no sense, essentially not since non sequitur so sec Witter the base there is like Think of the word sequence. We see that same sort of base in sequence a cz we see a non sequitur on that actually comes from the Latin meaning, like to follow something so it non sequitur means like it does not follow. So a non sequitur means something that just it's not part of the conversation. It's like a random comment is a non sequitur, so it does not follow. Non sequitur is one so non means not or no in a sentence. This is nonsense. Okay, so those are 10 useful prefixes, so you'll notice that a lot of these actually mean know or not. But that doesn't mean that we can just mix and match these so we can't add like, ah, on to the word logical. We can't say, like, unlock, tickle or maybe like dis logical. For example. We always need to use the same prefix with the same root word. So please be careful. Just because these prefixes mean the same thing doesn't mean that we can just pick and choose as we like. So it's still important to learn the correct prefix and the words that it regularly attach is too. So please keep this in mind as you study. All right, those are 10 useful prefixes.
