Morphology
chordoma = chord (opaque) = chord + oma
Though analyzable as 'chord' + '-oma', the term is a specialist medical name for a tumor from notochordal tissue and is not predictable by general learners from the common sense of 'chord'.
Etymology
Chordoma comes from a root meaning 'string' inside the body: chord means 'string' or 'cord', just like the common word cord, and the ending -oma means 'tumor'. So a chordoma is a tumor that grows from that 'cord' along the spine or base of the skull.
