Word History

Etymology

Noun (1)

earlier "roommate, person living in the same dwelling," perhaps by shortening & alteration from chamber fellow or chamber mate

Verb (1)

verbal derivative of chum entry 1

Noun (2)

of uncertain origin

Note: The word is apparently first attested along the New England coast. The Dictionary of American Regional English suggests a relation to "obs[olete] Engl[ish] & Scots dial[ect] chum food," but the sole attestation of such a word ("chum food, provision for the belly, Clydes[dale]") is in John Jamieson's Etymological Dictionary of the Scottish Language (1808). Possibly related is chum "a formless mass (of vegetables) from over-boiling," in the Dictionary of Newfoundland English, which points to Ulster Scots champ "potatoes, boiled and mashed," recorded in Joseph Wright's English Dialect Dictionary. This would presumably connect the word to champ entry 1.

Verb (2)

verbal derivative of chum entry 3

Noun (3)

probably borrowed from Chinook Jargon cəm "spotted, striped," from Lower Chinook c̓ə́m "variegated"
