Morphology

tentorium = tent (semi-transparent) = tent + orium

Formally built from 'tent' + Latin-derived suffix '-orium', so the 'tent-like' shape is inferable, but the specific anatomical meaning is technical and not directly derivable by a B1 learner.

Etymology

Tentorium comes from a Latin word for tent and is related to English words like tent and tension, from the root tend- meaning 'to stretch'. So a tentorium is a tent-like fold of the brain's covering that stretches over and supports the back part of the brain.
