History

Etymology

Two main origins: * Occupational surname for a physician, from Old English lǣċe (“doctor, physician”). * Topographic surname for someone who lived by a boggy stream, from Old English læcc (“boggy stream”) (related to Proto-Germanic *lekaną), or from several English placenames related to this (compare Leake).

From Middle English leche (“leachate; sluggish stream”), from Old English *lǣċ, *lǣċe (“muddy stream”), from Proto-Germanic *lēkijō (“a leak, drain, flow”) (compare Proto-Germanic *lekaną (“to leak, drain”)), from Proto-Indo-European *leǵ- (“to leak”). Cognate with Old English leċċan (“to water, moisten”), Old English lacu (“stream, pool, pond”). More at leak, lake.

From Middle English *lechen, *lecchen, from Old English leċċan, from Proto-Germanic *lakjaną, from Proto-Indo-European *leǵ- (“to leak”).
