"Don't" is a contraction of:
- did not
- does not
- do not
- would not
Show answer and solution
Correct answer: C. do not
1. A contraction shortens a word group by omitting internal letters.
2. "Don't" omits the "o" in "not" and joins it to "do".
3. Did not, does not and would not become didn't, doesn't and wouldn't.
**Why not the others:** Didn't, doesn't and wouldn't come from the other three forms.
