Morphology

straight + arch

The phrase 'straight arch' is directly compositional: the adjective 'straight' modifies 'arch', so a learner who knows both words can infer it refers to an arch with straight (horizontal) elements rather than a curved one. While the definition includes technical details (e.g. voussoirs), the core meaning is transparent and follows a common adjective+noun pattern that is easily understandable.

Etymology

Straight arch comes from the simple image of an arch with a flat, straight top made from many stones cut like wedges. Those stones press together like a row of teeth to hold the weight, so the name points to a 'flat' top rather than a 'curved' one.
