Question

Is the verb "to learn" in the past tense? What is the difference between "learned" and "learnt"? Is "to learn" a regular or an irregular verb?

Answer 1

See explanation.

Explanation:

To learn is an infinitive, therefore it has no tense defined.

The verb is irregular in British English with forms learnt for Past Simple and Past Participle, while in American English it is regular (i.e. Past Simple and Past Participle is learned)
