Etymology
Old EnglishMiddle EnglishBritish English
The -t ending in 'learnt' (instead of -ed) comes from the Old English strong verb 'leornian', whose past form was 'leornode' — the -t ending became standard in British English during the 16th–17th centuries as part of a wider shift affecting verbs like 'burn' (burnt), 'spell' (spelt), and 'dream' (dreamt). In American English, the regular -ed pattern ('learned') prevailed due to Noah Webster's reforms in the early 1800s.
