gum (1)

"resin," c.1300, from O.Fr. gomme, from L.L. gumma, from L. gummi, from Gk. kommi "gum," from Egyptian kemai. The verb, in the transferred fig. sense of "spoil, ruin" (usually with up) is first recorded 1901, probably from the notion of machinery becoming clogged. As a shortened form of chewing gum, first attested 1842 in Amer.Eng.; gumshoe "plainclothes detective" is from 1906, from the rubber-soled shoes they wore (which were so called from 1863). Gum-tree (1676) was so called for the resin it exudes.
