Etymology
From Middle English who, hwo, huo, wha, hwoa, hwa, from Old English hwā (dative hwām, genitive hwæs), from Proto-West Germanic *hwaʀ, from Proto-Germanic *hwaz, from Proto-Indo-European *kʷos, *kʷís. The sound change /hw/ > /h/ (without a corresponding change in spelling) was due to wh-cluster reduction after an irregular change of /ɑː/ to /oː/ in Middle English (instead of the expected /ɔː/) and further to /uː/ regularly in Early Modern English. A similar change occurred in two. Compare how, which underwent wh-reduction earlier (in Old English), and thus is spelt with h. Compare Scots wha, West Frisian wa, Dutch wie, Low German we, German wer, Swedish vem, Danish hvem, Norwegian Bokmål hvem, Norwegian Nynorsk kven, Icelandic hver.
