Your coworker asks about your sister and you say "She very beautiful." The food lands on the table and you say "This food delicious." You come in from the wind and say "I so tired." Every one of those sentences is missing the same word, and it's one of the common English mistakes Chinese speakers get corrected on without the correction ever sticking.
What you were told is "English needs the verb to be." True, and useless, because it doesn't explain why your mouth left it out in the first place. It also doesn't touch the other sentence you say, the one about the movie you liked: "I very like it." That looks like a separate mistake. It isn't.
Both sentences come from one Mandarin word, 很 (hěn), and one bad translation of it. 很 sits right after the subject in 她很漂亮 and in 我很喜欢, and your English textbook told you it means "very." It mostly doesn't. So the word crosses the border wearing the wrong label, and depending on what follows it, you get one of two results.
Either "very" takes the place where English wanted is, and you say "She very beautiful." Or it lands in front of a verb, where English won't take it at all, and you say "I very like it." One mistranslated word, two mistakes that look nothing alike.
In Mandarin, the adjective is already the verb
Take 她很漂亮 (Tā hěn piàoliang). Word by word, that's she / hěn / beautiful. There's no 是 (shì) anywhere in it, and 是 doesn't go in front of an adjective like this. 漂亮 isn't sitting around waiting for a verb to arrive. 漂亮 is the verb.
This is why linguists writing about Chinese often prefer the term stative verb to "adjective." A word like 累 (lèi, tired) or 忙 (máng, busy) does the whole job of a predicate by itself. The zero copula entry puts the contrast about as bluntly as it can be put: 我是开心 is wrong, 我开心 is right.
You can watch the same boundary get crossed from the opposite side. English speakers learning Chinese say 他是高 (Tā shì gāo) for "he is tall," and an introductory Chinese grammar reference calls that a classic mistake that almost everyone makes. They insert 是 because English trained them to. You delete "is" because Mandarin trained you to. Same line, two directions.
Mandarin does have "to be." It just goes with nouns
我是学生 (Wǒ shì xuésheng). 这是我男朋友 (Zhè shì wǒ nánpéngyou). You say those with 是 in them every day without thinking about it, and in English you say "I am a student" and "This is my boyfriend" correctly, also without thinking about it. The copula isn't missing from your grammar. It's filed under nouns.
That's the actual rule on the Mandarin side. 是 only links two nouns; it doesn't link a noun and an adjective. Wikipedia's grammar overview says the same thing in drier words: 是 is normally only used when its complement is a noun or noun phrase. Advanced patterns like 是…的 do put 是 near an adjective, and you can ignore them for now.
So stop telling yourself "Chinese has no verb to be." It has one. Mandarin draws a line at nouns, and English doesn't draw a line at all. If what comes after the subject is a description, English still wants a verb in there, and be is the verb it wants.
很 is not "very." It's a spacer
Go back to 她很漂亮. If someone asks you what that means, you probably say "she is very beautiful." It usually doesn't mean that. It means "she's pretty." Neutral. No emphasis.
很 in that sentence is a spacer. Wikipedia's article on Chinese adjectives calls it a dummy linking adverb that doesn't carry the meaning "very," and Wiktionary's usage note adds that with one-syllable adjectives like 累 and 忙, 很 gets added without any actual meaning, because Mandarin dislikes leaving a one-syllable predicate standing alone. Put real stress on it and 很 does mean "very," as Language Log's discussion of the word notes. Unstressed, it's holding the position. When you actually want "very," the word is 非常 (fēicháng): 他非常高 (Tā fēicháng gāo), 非常感谢 (fēicháng gǎnxiè).
Try dropping 很 and you'll hear what it was holding down. A bare adjective predicate usually reads as a comparison. 我好,你坏 (Wǒ hǎo, nǐ huài) is "I'm good, you're bad," which sets up a second half instead of describing anybody; the Chinese-linguistics discussion on Language Log quotes Maiheng Dietrich saying a predicate adjective without 很 implies a comparison. 姐姐漂亮,妹妹不漂亮 (Jiějie piàoliang, mèimei bú piàoliang) works the same way: the older sister is good-looking, the younger one isn't. One sister, then the other.
"I very like it" comes from the same word
我很喜欢 (Wǒ hěn xǐhuan) is "I really like it." Here 很 isn't standing in for anything, because 喜欢 is a verb and the sentence already has one. It's just sitting in front of the verb the way it sits in front of 漂亮. Translate it as "very," keep it where it was, and you get "I very like it."
English won't take it there. Longman's usage note is two lines long: you use very with adjectives and adverbs, and you use very much with verbs. You can hear the rule if you push it. "She is very happy" is fine, "He drives very fast" is fine, "He very drives" is nonsense. Someone asked Language Log this exact question and the answer was that degree modifiers like very combine with adjectives and adverbs but not verbs, with no deeper reason underneath. It's arbitrary. Don't look for the logic, just learn the swaps:
- I really like it. (before the verb)
- I like it a lot. (after the object)
- I like it very much. (after the object)
- I very much like it. (correct, but stiff enough that it sounds like a letter of complaint)
- Not: "I like it very."
Same for 我很想去 (Wǒ hěn xiǎng qù), which is "I really want to go."
Expect this one to outlast your grammar knowledge. 很 has years of automatic use behind it and "very" doesn't, so it tends to resurface when you speak fast, in the same way he and she come out wrong when you stop watching. You know the rule. Your production speed doesn't.

"I am agree." "He is want to go." "I am very agree." Somebody told you to add "is," and the rule started spreading into places it doesn't belong.
That one isn't Mandarin talking, though. 我同意 (Wǒ tóngyì) has no copula in it either, and Wiktionary lists 同意 as a transitive verb, the same part of speech "agree" has in English. It looks more like the correction overshooting, which is what happens when the instruction is "add is" instead of "add is before descriptions." Different cause, so the fix is different too: nothing to unlearn here, you just need a sharper version of the English rule.
Add be when what follows is an adjective or a noun. Don't add it in front of a plain verb like agree or want:
- I am tired. (adjective)
- I am a student. (noun)
- I agree. (verb, nothing added)
- He wants to go. (verb, nothing added)
- Not: "I am agree." Not: "He is want to go."
Where the missing "is" actually costs you
你忙吗?(Nǐ máng ma?) builds a yes-or-no question by hanging 吗 on the end and changing nothing else. English puts a verb at the front instead, and you can't move a verb that isn't there. You need "Are you busy?", so the whole question depends on the word you keep dropping. Describing people is the easy case. Questions cost you more, and so do the next two.
Negatives. 我很饿 (Wǒ hěn è) is "I'm hungry." Negate it and 很 vanishes: 我不饿 (Wǒ bú è), three syllables, no copula, which becomes "I not hungry" if you carry the shape straight over. English wants "I'm not hungry." That vanishing 很 is the clearest evidence you'll get that it was holding a position rather than carrying a meaning. 不 took the slot and nothing was lost.
The past. 电影很好看 (Diànyǐng hěn hǎokàn) is "the movie was good." It's also "the movie is good." Mandarin doesn't say which, and English won't let you not say, so the missing word is now carrying tense on top of everything else. You already met that problem from the other side, with the -ed ending.
One more thing. Contract it. Native speakers default to "I'm tired," "she's pretty," "it's cold." The full form turns up mainly under emphasis or in writing. If you say "I am tired" in a bar, nothing is wrong and everything sounds careful.
Sort the word before you say the sentence
Ten words: tired, agree, hungry, want, cold, like, busy, know, nervous, need. Put them in two piles.
Adjectives go left: tired, hungry, cold, busy, nervous. These need be, and they take very happily. Verbs go right: agree, want, like, know, need. These don't need be in front of them, and very is illegal there.
Then build a sentence out loud from each word, contracted, with the intensifier attached: "I'm really hungry." "I really want to go." "It's very cold." "I know it well."
The sorting is the whole skill. Once the word is in the right pile, the copula and the intensifier both follow without a decision. Expect it to feel slow for a couple of weeks, because you'll be stopping mid-sentence to file a word you were about to say. That's also the argument for practicing out loud with someone instead of on paper, whether that's a patient friend or an AI conversation partner like Conversa. Silent practice rarely catches "I so tired," because on paper you have time to be right.
You're not adding a word that English has and Mandarin lacks. You're moving a word you were already saying. 很 was standing in that position the whole time, and English wants is there instead. Start with the sentence you say most often, whatever that is for you, and fix that one first. Reading about it fixes nothing. You already knew the rule.
