Morphology

subdural = dural (semi-transparent) = sub + dural

Formed by the productive prefix 'sub-' meaning 'below' plus 'dural' meaning 'relating to the dura mater'; the medical base is specialized, so the term may be unfamiliar to general learners.

Etymology

The word subdural has two parts: sub- meaning 'under', like in subway or submarine, and dura meaning 'tough' or 'hard', as in durable and in dura mater, the brain's tough outer layer. So subdural means 'under the tough layer', which is why doctors use it for blood or fluid that gathers beneath the brain's outer covering.
