Morphology

pterygoid + muscle

The term is compositional: 'pterygoid' names a specific muscle and 'muscle' denotes the tissue that produces movement, so together they refer to that particular muscle involved in jaw movement. Although technical, this follows standard noun‑noun anatomical naming patterns common cross‑linguistically, so a learner who knows both constituents can infer the meaning.

Etymology

Pterygoid muscle comes from an old Greek word meaning 'wing'. The pterygoid part points to that 'wing-like' shape near the jaw, so the name helps you remember these muscles help move the lower jaw.
