Morphology

jam + session

The components 'jam' (a musical/poppish tune or musical activity) and 'session' (a meeting/time period) point toward a musical meeting, so a learner who knows both words can partially infer that it involves music. However, the specific idea of an informal, improvisational gathering of musicians is a conventionalized use of 'jam' and not fully predictable from the literal constituents (and 'jam' has other common senses), so full comprehension at B1 is not guaranteed without prior exposure.

Etymology

Jam session comes from early jazz clubs where musicians would jam—play together without planning—and a session is a meeting, so the phrase named those informal music get-togethers. One popular image is players mixing their ideas like fruit in a jar of jam, which helps explain why it now means a relaxed meeting to 'improvise' music.
