What is the irregular verb of feel?

Answer 1

Feel is sometimes called an irregular verb, though it is also called a strong verb.

A regular verb forms its past tense and past participle by adding [-ed] to the stem.

I walk, I walked, I have walked.

A strong verb is different -- it changes to another form.

I feel, I felt, I have felt.

This form comes from older English, and is the same for the verb kneel (knelt). Strong verbs include give (gave) and stick (stuck).
