Morphology

reentrance = entrance (opaque) = re + enter + ance

The structure is formally regular, but this architectural sense is a specialized extension that ordinary learners will not infer from the base parts.

Etymology

Reentrance comes from re- 'again' and entrance 'enter', and it helps to think of a shape that 'enters' back into itself. So a geometric or architectural reentrance is an inward curve or corner that makes a recess in the wall or shape.
