Etymology 2

Possibly related to Middle English leren, from Old English lǣran (“to teach, instruct, indoctrinate”), from Proto-West Germanic *laiʀijan, from Proto-Germanic *laizijaną (“to teach”), from *laizō (“lore, teaching", literally, "track, trace”), from Proto-Indo-European *leys- (“to track, furrow”). Cognate with Scots lere, leir, Saterland Frisian leere, West Frisian leare, Dutch leren, German lehren, Danish lære, Swedish lära. See also lear, lore. But normally the Middle English word would give lere, not learn.
