Where it comes from

From Middle English soile, soyle, sule (“ground, earth”), partly from Anglo-Norman soyl (“bottom, ground, pavement”), from Latin solium (“seat, chair; throne”), mistaken for Latin solum (“ground, foundation, earth, sole of the foot”); and partly from Old English sol (“mud, mire, wet sand”), from Proto-Germanic *sulą (“mud, spot”), from Proto-Indo-European *sūl- (“thick liquid”). Cognate with Middle Low German söle (“dirt, mud”), Middle Dutch sol (“dirt, filth”), Middle High German sol, söl (“dirt, mud, mire”), Danish søle (“mud, muck”). Compare French seuil (“level; threshold”) and sol (“soil, earth; ground”). See also sole, soal, solum. For the sole and soil relation, compare typologically Russian по́чва (póčva) akin to подо́шва (podóšva).
