From Middle English miller, meller, millere, from earlier mylner, mylnere, milnere, from Old English *myllere, *mylnere, perhaps an assimilation or corruption of Old English mylnweard (“mill-keeper”), or from late Proto-Germanic *muljāriaz, *mulinārijaz (“miller”), equivalent to mill + -er; cf. also Late Latin molīnārius. Cognate with Saterland Frisian Muller (“miller”), Dutch mulder, molenaar (“miller”), Low German Möller (“miller”), German Müller (“miller”), Danish møller (“miller”), Swedish mjölnare (“miller”), Icelandic mylnari (“miller”).
