Surface Forms

traffic jam singular
traffic jams plural

Morphology

traffic + jam

The meaning is directly derivable from combining 'traffic' (flow of vehicles) with 'jam' (a crowding or blockage); a B1 learner who knows both senses would infer a situation where vehicles are stuck or moving slowly. This compositional pattern is common and found in many languages, making the expression immediately comprehensible in context.

Etymology

Traffic jam may come from the picture of cars all squeezed together like jam in a jar: traffic means moving vehicles and jam once meant a tight crowd or blockage. So, it now means many vehicles are 'stuck' or 'moving very slowly'.
