Old English hwilc (West Saxon) "which," short for hwi-lic "of what form," from Proto-Germanic *khwilikaz (cf. Old Saxon hwilik , Old Norse hvelikr , Swedish vilken , Old Frisian hwelik , Middle Dutch wilk , Dutch welk , Old High German hwelich , German welch , Gothic hvileiks "which"), from *khwi- "who" (see who ) + *likan "body, form" (cf. Old English lic "body;" see like (adj.)). In Middle English used as a relative pronoun where Modern English would use who , as still in the Lord's Prayer. Old English also had parallel forms hwelc and hwylc , which disappeared 15c.
