From Late Middle English *amusen (“to mutter, be astonished, gaze meditatively on”), from Old French amuser (“to stupefy, waste time, be lost in thought”), from a- + muser (“to stare stupidly at, gape, wander, waste time, loiter, think carefully about, attend to”), of uncertain and obscure origin. Cognate with Occitan musa (“idle waiting”), Italian musare (“to gape idly about”). Possibly from Old French *mus (“snout”) from Vulgar Latin *mūsa (“snout”) — compare Medieval Latin mūsum (“muzzle, snout”) –, from Proto-Germanic *mū- (“muzzle, snout”), from Proto-Indo-European *mū- (“lips, muzzle”). Compare North Frisian müs, mös (“mouth”), German Maul (“muzzle, snout”). Alternative etymology connects muser and musa with Frankish *muoza (“careful attention, leisure, idleness”), from Proto-Germanic *mōtǭ (“leave, permission”), from Proto-Indo-European *med- (“to acquire, possess, control”). This would make it a cognate of Dutch musen (“to leisure”), Old High German *muoza (“careful attention, leisure, idleness”) and muozōn (“to be idle, have leisure or opportunity”), German Muße (“leisure”).
