Quick Answer: What Is the Past Tense of Keep?

Common Mistakes With Keep and Kept
Learning the correct form also means recognizing common errors.

Why? Keep is irregular, and its past tense is kept.

Why? The word “yesterday” indicates the past, so kept is required.

Correct: I have kept the receipt.
Why? The present perfect tense requires the past participle, kept.
Mistake 4: Using “Kept” After Did
