Morphology

speed + bump

The figurative meaning 'a problem or obstacle that slows progress' follows directly from combining 'speed' (how fast something moves) with 'bump' (a raised obstruction that slows vehicles): the literal image maps clearly onto a minor impediment to progress. This road‑bump metaphor is common cross‑linguistically and follows a simple compositional/metaphorical pattern, so a B1 learner who knows the constituents can readily infer the meaning.

Etymology

Speed bump comes from the real raised hump on a road. The word bump is the small rise your car feels and speed is what it reduces, so drivers must 'slow down' when they pass it.
