Morphology

segmental + arch

The head noun 'arch' and the adjective 'segmental' (derived from 'segment') give a compositional cue: the arch is related to a segment rather than a full semicircle. However, the precise architectural sense — that the curve is specifically less than a semicircle — is somewhat technical and could be misinterpreted by learners as merely 'made of segments' or 'having parts', so the meaning is partially but not fully predictable for a B1 learner.

Etymology

The noun segmental arch is an arch and the word segmental points to a small 'segment' of a circle, so its curve is less than a half circle. Builders used this lower, flatter curve to make openings that still carry weight, so today segmental arch means an arch with a low, efficient curve.
