Morphology

musculus + abductor + pollicis

The elements 'musculus' and 'abductor' transparently indicate a muscle that abducts (moves a part away), so a learner knowing those parts could infer this is a muscle that moves something laterally. However, 'pollicis' is a Latin anatomical term (not found in the provided dictionary entry) and does not obviously mean 'thumb' to a B1 learner, so the exact referent is not predictable without anatomical or Latin knowledge.

Etymology

Musculus abductor pollicis comes from old Latin words: musculus meaning 'muscle', abductor meaning 'to move away', and pollicis meaning 'thumb'. It names the muscle that pulls the thumb away from the palm, so the name tells you what the muscle does.
