Morphology

tuberosity = tuberous (semi-transparent) = tuber + ous + ity

Built from the adjective 'tuberous' + '-ity' (noun-forming); the morphological steps are regular but the anatomical meaning is specialized and an orthographic contraction (tuberous → tuberosity) can obscure the relation for learners.

Etymology

Tuberosity comes from the Latin tuber, meaning 'lump' or 'swelling', and you can think of a potato 'tuber' as a round lump. That's why a tuberosity is a rounded bump on a bone where a muscle or ligament attaches.
