- who
[who 词源字典] - 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.
