- also kelson, 1620s, altered (by influence of keel (n.)) from Middle English kelsyng (late 13c.), which probably is of Scandinavian origin (compare Swedish k?lsvin, Danish and Norwegian kj?lsvin, from root of Old Norse kj?lr; see keel (n.)) + swin "swine," used of timber (see swine). Or else from a similar Low German source.
