Morphology

oral + cavity

The term is a straightforward adjective + noun composition: 'oral' (pertaining to the mouth) + 'cavity' (a hollow), so the meaning 'a hollow/space in the mouth' is directly derivable from the constituents. This is a common anatomical construction with clear cross-linguistic parallels, so a B1 learner who knows both words would understand the MWE.

Etymology

Oral cavity names the empty space inside the mouth: oral means 'of the mouth' and cavity means 'a space' or hollow. That's why the phrase points to the opening and inner area where we take food and make speech sounds.
