Morphology

protrusion = protrude (semi-transparent) = pro + trude + ion

The noun is regularly formed from the verb 'protrude', but the concrete sense of a thing that sticks out is slightly more specific than the base verb.

Etymology

Protrusion comes from the Latin parts pro- 'forward' and trudere 'to push'. So a protrusion is something 'pushed forward' — in other words, something that sticks out from a surface, like a small bump that protrudes.
