"make a contraction" vs. "make contractions"

Question

From a tutorial (Transcript)

He is --> He’s They will --> They’ll Do not --> Don’t But which words can you make contractions from?

I understand the rules of contractions. I'd just like to know whether I should singular when talking about just one occurrence.

For example,

He is --> He’s

should I say

make a contraction from "He is"

or

make contractions from "He is"

Is what I get, "he's", the contraction?

Are there any other expressions clearer and more natural could be used here?

Answer 1

I'd just like to know whether I should singular when talking about just one occurrence.

Since we are taking about one specific contraction here, we will use the contraction.

should I say

make a contraction from "He is"?

That doesn’t sound natural.

Consider these:

What is the contraction for “he is”?

• The contraction for he is is he’s.

What is the contraction for “do not”?

• The contraction for do not is don’t.
