Morphology

amniotic + cavity

The meaning 'the fluid-filled space surrounding the developing embryo' is directly derivable from 'amniotic' (relating to the amnion/fetal membranes) combined with 'cavity' (a hollow or space). This is a compositional adjective+noun biomedical term following standard word-formation patterns, so a B1 learner who knows both constituents would readily infer the MWE's meaning.

Etymology

Amniotic cavity combines amniotic (the sac around the baby) and cavity (a hollow space). It is the watery 'room' inside this sac where the developing baby floats and is protected.
