Morphology

pavor + nocturnus

The phrase is Latin (pavor = fear, nocturnus = of the night), so a learner who explicitly knew those roots could infer a basic 'night-fear' meaning and relate it to night terrors. However, it is a medicalized Latin term used in English and does not follow ordinary English composition patterns, and the full clinical sense (intense non‑REM panic/screaming) is not fully predictable from the literal parts, so transparency is only partial.

Etymology

Pavor nocturnus comes from Latin words pavor ('fear') and nocturnus ('night'), so it literally means 'night fear'. It describes a sudden, strong panic that happens while someone is sleeping, which is why it now means a very severe night terror.
