‘Learnt’ or ‘learned’?

These are alternative forms of the past tense and past participle of the verb learn. Both are acceptable, but learned is often used in both British English and American English, while learnt is much more common in British English than in American English.

So that’s it.

It’s correct: “learnt”, although not common usage.

Caught your post just as I was preparing to post on the same thing. Learnt is not a word, it is slang. Wonder if it was a direct quote from Riannah (or however you spell that made-up name)
