Morphology

round + the + bend

The sense 'crazy' cannot be predictably derived from the literal meanings of 'round' (to go around) and 'bend' (a curve); the phrase denotes a mental state rather than a physical location. This is an informal, language-specific idiom/metaphor (common in British English) that B1 learners who only know the constituents are unlikely to infer without prior exposure.

Etymology

The idiom round the bend may come from the picture of someone going round a sharp bend in the road and moving out of sight or away from the usual path. So, if someone is round the bend, they are seen as 'not thinking or behaving normally', in other words 'crazy'.
