Morphology

flat + arch

This is a straightforward modifier + noun composition: 'flat' describes the shape of an 'arch', so a learner who knows both words can infer an arch with a flat or horizontal profile. While the technical detail about voussoirs is specialized, the core meaning is transparently derived from the constituents and is cross-linguistically obvious.

Etymology

The building term flat arch names a kind of arch that looks flat instead of curved. It is made from a row of stones cut like wedges that press together to 'hold up' the wall, so even without a curve it works like an 'arch' today.
