Can I contract have in this sentence?
My parents have just arrived
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.
The 've contraction works with:
Those not listed above, including "my parents have", cannot usually be contracted in the same manner.
My parents have just arrived
You may alternatively choose to refer to your parents as "they" and therefore use "they've" in your sentence.
My parents (they) have just arrived.
- They've just arrived.
- Who?
- My parents.
- They must've been traveling all day.
In addition to whether it is possible to be used, it should also be noted that contractions such as these are generally more informal and something should be avoided. When writing an academic paper, for example, it is often advised to use the full phrase ("I have" or "should have") instead of opting for the contraction.
As far as I'm aware, verbs are usually only contracted when they are:
Examples: (bold text indicates stress/emphasis)
[with the verb 'to have']
I've seen it — A simple statement of fact; can be contracted
I have seen it — An emphasis to contradict or reaffirm; can't be contracted
I've got money* — as above
I have got money* — as above
*There's an exception in en-US, where they favour using 'have' as a main verb, which does not get contracted:
I have money / I have money
[with the verb 'to be']
I'm going to the party — contraction attached to stressed word, contraction not stressed
She's going to the party — as above
But, in answer to the question, "Who's going to the party?"
I am — main* verb, no contraction even though not stressed
She is — as above
— You can't answer the question solely with *I'm or *She's.
*Due to ellipsis (here, I am is short for I am going) the auxiliary verb functions as the main verb.
A similar emphasis rule appears with the adverb, 'not':
I didn't eat the cake
I did not eat the cake
I'm happy to be corrected and make edits as necessary.
One thing to remember is that there is a difference between speech and writing. In writing, there is a clear separation between using a contraction and not using one. If you don't have an apostrophe, it's not a contraction. But, in speech, people often drop syllables and otherwise change their pronunciations when talking fast, even when there is no standard way to express that in writing.
So, if I am talking naturally, I might say something that sounds sort of like
My parentsa just arrived.
but you would write it as
My parents have just arrived.
In transcribed speech, there are many such "hidden contractions". In the past few decades, you have started to see "gonna" in writing, but but most newspapers still use "going to" even when "gonna" is a better written approximation of the sounds the person made.
