which

which: [OE] Etymologically, which means ‘what like, of what form or sort?’ The word was formed in the prehistoric Germanic period from the interrogative base *khwa-, *khwe- (source of English what, who, etc) and *līka- ‘body, form’ (source of English like and also incorporated into English each and such). Its Germanic relatives include German welch and Dutch welk ‘which’.

which (pron.)

Old English hwilc (West Saxon, Anglian), hw?lc (Northumbrian) "which," short for hwi-lic "of what form," from Proto-Germanic *hwa-lik- (cognates: 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 *hwi- "who" (see who) + *likan "body, form" (cognates: 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.
