In normal speech, most people pronounce unaccented have as /əv/, and so it would make sense to write it "'ve".

But in fact, this is not common except in I've and they've, (where it loses the vowel and sounds like /v/), and in the forms would've, should've and could've.

You can find other examples occasionally, but they're not common. For example, in the iWeb corpus there are 36 instances of people've, compared with 20820 of should've, and 449 594 of they've.

They had set up the stand. Good job reading those sentences! Try reading the next sentence below. Tell your parent or teacher what the contraction is, and what two words make up that contraction: We'd better get to school! The contraction in the sentence you just read is we'd. If you break up the word "we'd," you will have the words "we" and "had."

What are contractions?
Contractions are two or more words that are combined and shortened to save time. Typically, you can identify a contraction by the apostrophe, as with isn’t or they’ve—but don’t confuse contractions with possessive nouns, which also use apostrophes.

August 10, 2022 - Contractions take words that usually go together, like can not or I have, and then remove certain letters to shorten them and make other words, like can’t or I’ve. Contractions are an incredibly useful way to save time in both writing and speech, but there are a lot of rules about when and how to use them (for example, in formal writing they’re considered inappropriate).

Such contractions represent the most useful job the apostrophe does for us, since, without it, we would have no way of expressing in writing the difference between she'll and shell, he'll and hell, can't and cant, I'll and ill, we're and were, she'd and shed, we'll and well, and perhaps a few others.

Answer (1 of 10): I can’t agree that “he have” is always wrong; think of the question, “Will he have a hat?” However, this is an outlier, and so unusual that it would not be appropriate to contract it. Contractions are used to elide/shorten commonly used phrases, just as abbreviations ...
