Morphology

triceps = tri + ceps

The prefix 'tri-' clearly signals 'three', but the combining form '-ceps' is a Latin-derived, non-standalone element meaning 'head' and is not a familiar English word, so learners can only partially infer 'three-headed muscle'.

Etymology

Triceps breaks into tri- meaning 'three' and -ceps from caput meaning 'head', the same pattern you see in biceps and quadriceps. So triceps literally means 'three-headed', which fits because the muscle has three parts that help straighten the arm.
