smother

From Middle English smothren, smortheren, alteration (due to smother, smorther (“a suffocating vapour, dense smoke”, noun)) of Middle English smoren (“to smother”), from Old English smorian (“to smother, suffocate, choke”), from Proto-West Germanic *smorōn, from Proto-Germanic *smurōną (“to suffocate, strangle”), probably related to *smallijan (“to burn”) or Old English smoca (“smoke”).

Cognate with Middle Low German smoren, smurten (“to choke, suffocate”), West Flemish smoren (“to smoke, reek”), Dutch smoren (“to suffocate, smother", also "to stew, simmer”), German schmoren (“to stew, simmer, braise”).
