Question

which is the correct past tense of leap leapt or leaped?

Answer 1

This may surprise you, but both “leapt” and “leaped” are acceptable past-tense and past-participial forms of the verb “leap.” It's fine to use either one. According to Garner's Modern American Usage, traditionalists prefer “leapt,” so if you want to keep the grammar curmudgeons happy, stick with that.

Answer 2

Both are correct but mostly leapt used as past tense
