mummer

Origin

From Middle English mummer, mommer, equivalent to mum + -er, perhaps conflating with Old French momeor (“jester, entertainer”), from mommer (“to wear a mask”), from momon (“mask”). Compare German Mumme (“mask”), 16th Century German mummen (“to disguise oneself”), Middle Dutch mommen, mummen (“to go about in a mask, to disguise”), Middle Low Saxon mommen (“to wear a mask, to disguise”), Dutch mom (“mask”) and mimmen (“to mask”) as well as Spanish momo (“grimace”). Perhaps both of the conflated terms are from the same ultimate root, as note Middle Low Saxon mummen (“to speak indistinctly, to disguise oneself”), Dutch mommen (“to speak indistinctly”), German mummen (“to speak indistinctly”), English mump (“to grimace, mumble”).
