Morphology
The meaning is directly compositional: 'frontal' (pertaining to the front/forehead) combined with 'sinus' (an air-filled cavity) yields an air-filled cavity in the frontal bone above the eyes. This follows standard noun–modifier composition and has clear parallels in other languages and medical terminology, so a B1 learner who knows both constituents can reliably infer the meaning.
Etymology
Frontal sinus comes from two simple words: frontal meaning 'forehead' and sinus meaning 'hollow' or 'pocket'. That's why the name literally points to the small air space just above the eyes at the front of the skull.
