词源

Late Middle English kelswayn, from Low German kielswîn, kielswīn, from kiel (“keel of a ship”) (from Old Norse kjǫlr) + swin (“swine”), used as the name of a timber (however, compare sill). Compare with Dutch kolzwijn, kolsem, Low German, kielswîn, German Kielschwein, Danish kølsvin, kölsvin, all with the same meaning.
