wean: [OE] The etymological notion underlying wean is of ‘becoming accustomed’. The specialization to ‘making accustomed to food other than mother’s milk’ is a secondary development. The word comes from a prehistoric Germanic *wanjan (source also of German gewöhnen ‘accustom’). This was derived from the adjective *wanaz ‘accustomed’, which in turn was formed from the base *wan-, *wen-, *wun-(source also of English winsome, wish, and wont ‘accustomed’ [OE]). => winsome, wish, wont[wean etymology, wean origin, 英语词源]
