Morphology

third + ventricle

The meaning is directly and compositionally derived from 'third' (the ordinal number three) + 'ventricle' (a brain cavity), so it denotes the third such brain cavity in sequence. This is a transparent, technical anatomical label that follows straightforward compositional logic (and similar labels exist in other languages), so a B1 learner who knows both constituents would understand it.

Etymology

Third ventricle is named for a small, narrow chamber in the middle of the brain where clear fluid flows. Think of third as the middle one and ventricle as a little room, so the phrase means the 'narrow, fluid-filled space' that connects other parts of the brain.
