First attested in the early 18th c. as a verb meaning “to press, be pressed, be wedged in”. Compare dialectal jammock (“to press, squeeze, crush into a soft mass, chew food"; also "a soft, pulpy substance”). Perhaps from Middle English chammen, champen ("to bite upon something, gnash the teeth"; whence modern champ, chomp), of uncertain origin; probably originally onomatopoeic. The "performance" sense is first attested with regards to jazz in 1929, and its origin, though uncertain, is likely metaphorical, "something sweet made by the combination of many things", with influence from jamboree.

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
