From Middle English fle, from Old English flēah, flēa, from Proto-West Germanic *flauh, from Proto-Germanic *flauhaz (compare West Frisian flie, Low German Flo, Flö, Dutch vlo, German Floh, Icelandic fló), from pre-Germanic *plóukos, *plówkos, from or akin to Proto-Indo-European *plus- (compare Latin pulex, Sanskrit प्लुषि (plúṣi)). The archaic plural fleen is from Middle English fleen, flen, from Old English flēan (“fleas”).
