Simplified etymology

Jam, the fruit preserve, has been used since the 18th century and probably takes its name from the verb jam, “to cram” or “to squeeze,” although that verb’s origin is uncertain. Jams of logs being floated down rivers are recorded from the beginning of the 19th century, and references to carriage jams appear by the 1850s.

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.
