Morphology
trumpet + arch
The compound signals a relation between 'trumpet' and 'arch' so a learner who knows both words can plausibly infer an arch that resembles or relates to a trumpet-shaped form. However, the precise technical sense (a conical squinch used to support a dome over a square room) is specialized and not fully predictable from the common meanings, so full comprehension requires exposure or domain knowledge.
Etymology
Trumpet arch gets its name from the shape: the corner element flares out like a musical trumpet while forming an arch in the corner. This flared piece helps 'support a dome' and lets builders move from a square room to a round dome, so the name links the shape to its job.
