Morphology

functional + disorder

The phrase literally combines 'functional' (relating to how something works) and 'disorder' (a medical/mental condition), so a B1 learner who knows both words can infer it refers to a problem with functioning rather than a structural injury. However, the technical nuance — that symptoms occur without an identifiable physiological or anatomical cause — is a specialized medical meaning not fully predictable from the constituents alone. Because the core idea is partly transparent but the clinical implication requires prior exposure, it is best classified as semi-transparent.

Etymology

Functional disorder comes from medicine and paints a simple picture: functional refers to 'function' or 'how the body works' and disorder means it is not working right. So the phrase explains real symptoms when tests show 'no visible damage', because the problem is with function, not a broken part.
