who: [OE] Who goes right back to Indo-European *qwos, *qwes (source also of Russian kto ‘who’), whose neuter form *qwod gave English what. Its prehistoric Germanic descendant was *khwaz, *khwez, which has evolved into German wer, Dutch wie, Danish hvo, and English who. Whom comes from the Old English dative form hwǣm.
who (pron.)
Old English hwa "who," sometimes "what; anyone, someone; each; whosoever," from Proto-Germanic *hwas (cognates: Old Saxon hwe, Danish hvo, Swedish vem, Old Frisian hwa, Dutch wie, Old High German hwer, German wer, Gothic hvo (fem.) "who"), from PIE *kwo-, stem of relative and interrogative pronouns (cognates: Sanskrit kah "who, which;" Avestan ko, Hittite kuish "who;" Latin quis/quid "in what respect, to what extent; how, why," qua "where, which way," qui/quae/quod "who, which;" Lithuanian kas "who;" Old Church Slavonic kuto, Russian kto "who;" Old Irish ce, Welsh pwy "who").
