Morphology

stylomastoid = styloid + mastoid (opaque) = stylo + mastoid

The term is a technical compound of two anatomical terms ('styloid' and 'mastoid') that are unlikely to be known by an average B1 learner, so the composition is not useful for general-learner inference.

Etymology

The word stylomastoid combines stylo- ('pillar' or 'point'), as in stylus, and mastoid ('breast-shaped bump'). So stylomastoid names the place on the skull where a thin, pointed bone part meets a rounded bump, which is why doctors use it for that area.
