    Academic text (1992)

Morphology

triceps + brachii

The term is compositionally interpretable: 'triceps' denotes a three-headed muscle and 'brachii' is the Latin genitive relating to the arm, so together they mean the three-headed muscle of the upper arm. However, because 'brachii' is a specialized Latin anatomical element and the form is technical rather than a regular English noun phrase, an average B1 learner (even if they know the parts) may not reliably parse the genitive relation or recognize the Latin element, making the transparency only partial.

Etymology

Triceps brachii: The name triceps brachii comes from Latin: triceps means 'three-headed' and brachii means 'of the arm'. Picture a muscle with three parts on the back of the upper arm that pull together to straighten the elbow, so the name shows why it 'extends the forearm'.
