Morphology

posterior + nasal + aperture

The phrase is transparently compositional: 'posterior' (rear) + 'nasal' (relating to the nose) + 'aperture' (opening) yields the clear sense 'rear opening of the nasal cavity.' This anatomical description follows straightforward word-combination patterns found across languages, so a B1 learner who knows the constituent words can reliably infer the meaning.

Etymology

Posterior nasal aperture comes from older words: posterior meaning 'back', nasal meaning 'nose', and aperture meaning 'opening'. It paints the image of one of the two small openings at the back of the nose that lead into the throat, so the name simply means a 'back opening of the nose'.
