Morphology
The meaning 'an arch that forms a half-circle' is directly and transparently derived from combining 'semicircular' (having the form of a semicircle) with 'arch' (arched construction). This is a straightforward compositional noun phrase following regular English compounding and has clear parallels in other languages, so a B1 learner who knows the constituents will understand it.
Etymology
Semicircular arch is named for its shape: semi means 'half' and circular comes from 'circle', so the arch is literally a 'half circle' drawn from one center point. This half‑circle form moves the weight to the sides, which is why semicircular arches are strong and often used for doorways and bridges today.
