swine: [OE] Swine is the ancestral English term for the ‘pig’, and it remained the main word until pig began to take over from it in the early modern English period. It came from a prehistoric Germanic *swīnam, which also produced German schwein, Dutch swijn, and Swedish and Danish svin. And this in turn went back to Indo-European *su-, source also of English hyena and sow. => hyena, sow[swine etymology, swine origin, 英语词源]
