Etymology: From Middle English ȝameren, ȝaumeren, yemeren, ȝomeren, from Old English ġeōmrian (“to lament”), from Proto-West Germanic *jāmarōn, from Proto-Germanic *jēmarōną (“to show misery or sadness”), from Proto-Germanic *jēmaraz (“miserable, sorrowful, sad”), from Proto-Indo-European *yem- (“to hold, match, defeat”). Reinforced by cognate Middle Dutch jammeren (modern Dutch jammeren), from the same ultimate origin.
