leaped
I've never understood why writers of the regency period (especially) use the word leaped rather than leapt, and yet use the word learnt instead of learned. I feel more comfortable with it being leapt and learned. Learnt sounds so ignorant.https://writingexplained.org/learnt-vs-learned-difference
Here is a helpful trick to rememberlearnedvs.learnt, and it is a pretty simple one. You should probably never uselearnt. It is only common in British English as a past tense verb, and even in that context, it is overshadowed bylearned.
