Old English wull "wool, fine soft hair which forms the coat of some animals," from Proto-Germanic *wulno (cognates: Old Norse ull, Old Frisian wolle, Middle Dutch wolle, Dutch wol, Old High German wolla, German wolle, Gothic wulla), from PIE *wele- (1) "wool" (cognates: Sanskrit urna; Avestan varena; Greek lenos "wool;" Latin lana "wool," vellus "fleece;" Old Church Slavonic vluna, Russian vulna, Lithuanian vilna "wool;" Middle Irish olann, Welsh gwlan "wool").

Figurative expression pull the wool over (someone's) eyes is recorded from 1838, American English.
