What is the difference between learned and learnt?
Ostap77 is correct. In AmE learned is both the simple past and the past participle of learn. While learnt is a proper alternative for the past participle, we rarely hear it spoken.
Also (in Br English at least) 'learned' can be used as a two-syllable adjective that means 'educated' - 'a learnÚd person' (the second syllable often has a written accent).
hmmm.... thx for the answers. But what is AmE? Is it American spelling? So in summary...learned = American, learnt = British?
Your summary is an over-simplification that many people believe. As a British person who uses both 'learnt' and 'learned' I disagree. People have written something closer to the whole story in the foregoing posts.
We say learnt here.
I have always understood that there is a subtle difference:
"learned" is the past of the action of learning (e.g. Fred learned how to ride a bike)
"learnt" is the state that something (rather than someone) has been learned e.g. Mathematics was learnt.
The example with burned and burnt may be easier to explain:
The paper burned (i.e. it was on fire)
That piece of paper is burnt (i.e. the action of it being burned has caused it to be in a burnt state).
Happy to be told otherwise
