baste: There are two separate verbs baste in English, one meaning ‘sew loosely’ [14], the other ‘moisten roasting meat with fat’ [15]. The first comes from Old French bastir, which was acquired from a hypothetical Germanic *bastjan ‘join together with bast’. This was a derivative of *bastaz, from which English gets bast ‘plant fibre’ [OE]. The origin of the second is far more obscure. It may come from an earlier base, with the past form based being interpreted as the present tense or infinitive. [baste etymology, baste origin, 英语词源]
