What is the past tense of the verb “To learn”?

The past tense of 'To learn' is 'learnt'

"Learned." Now how am I supposed to avoid a one word answer? I have to keep typing for no reason now.

maybe is "learned"

Learnt and learned and US English is crazy enough to consider learnt a spelling error.
As per the dictionary (merriam-webster) 'Learnt' is the Chiefly British past tense and past participle of learn.

I learned (lol) in school that if the verb i want to put in past tense in not on the nice list my English teacher told us..then you put a nice "ed" at the end of that verb...and TAADAHH you've got yourself past tense!(The best part came with this "english is such a melodious language,please try to keep that in mind and DON'T MESS IT!"...my teacher's motto)...And becouse i don't recall the verb "to learn" on that list....I say it's "learned"

I was taught that 'learned' was correct but have recently been told that it's learnt, personally I prefer learned so that's the one I'll use.

I like and tend to use "learnt" in speech and writing BUT I've been corrected about a gazillion times by people who think "learned" is the only correct past tense. I still like "learnt". In fact the more they correct me, the more I like "learnt".

I think there are two candidates because one of them is the American English version. In England, we use I learnt, and in America, they use I learned. I guess 'learnt' is one of those quirky English words put there to confuse those from other countries who are learning our language. lol.

I can't explain the reason, but I can tell you one thing... my American English spellcheck marked learnt as wrongly spelt. ha ha ha. It's a bit like the passed tense of I mean, I suppose... we don't say I meaned, but I meant. Maybe that goes some way to explaining the reason why we don't use learned... a lazy way of speaking or writing, do you think?:-)

Brightest Blessings.

Learned
