jamming
B2Informal (music, tech, general), but also standard in transportation contexts (e.g., traffic jam).
Definition
Meaning
The act of pressing or crowding something into a space tightly; or playing music informally and improvisationally.
In technology, it means causing interference with signals. Informally, it can mean doing something skillfully or with great enjoyment ('jamming on a project').

Semantic Notes
Highly polysemous. The core is forceful insertion/blockage. The music sense is a metaphorical extension of things fitting together tightly and rhythmically. The 'doing something well' sense is slang.

FAQ
Frequently Asked Questions
No. While a common informal use, its primary meanings involve blocking or crowding. The music sense is a specific, metaphorical extension.
'Jamming' often implies a forceful insertion that causes the blockage (e.g., jamming a stick into a wheel), while 'blocking' is more general, meaning to obstruct a path or process.
It depends. For technical contexts (e.g., 'electronic jamming') it is formal. For music or general 'blocking', it's neutral to informal. Prefer 'obstructing' or 'congesting' in very formal prose.
Etymologically, both come from the verb 'to jam' meaning to press tightly. Fruit jam is made by pressing/crushing fruit. A traffic jam is vehicles pressed tightly together.
