From Middle English lernen (“to learn", also, "to teach"”), from Old English leornian (“to learn", rarely also, "to teach”), from Proto-West Germanic *liʀnōn, from Proto-Germanic *lizaną, from Proto-Indo-European *(le-)lóys-e, stative from the root *leys- (“track, furrow, trace, trail”). The spelling with ⟨ea⟩ is of Early Modern English origin and reflects a lengthening of /ɛ~e/ to /eː/ before /rn/ in Late Old English or Early Middle English, then later lowering to /ɛː/; the modern pronunciation reflects still later reshortening. Cognate with Old Frisian lernia, lerna (“to learn”), Middle Low German lernen (“to learn", also, "to teach”), Middle Dutch leernen (“to learn", also, "to teach”) (whence Dutch lernen (“to study scripture”)), German lernen (“to learn”). See also lore and lear.
