Morphology

dumb + mistake

The meaning 'a foolish or unwise error' is directly and transparently derived from combining 'dumb' (foolish/lacking judgment) with 'mistake' (an error). This adjective+noun composition is a common, predictable pattern (and mirrored in many languages), so a B1 learner who knows both words would readily infer the MWE's meaning.

Etymology

Dumb mistake joins dumb, meaning 'stupid' or 'not thinking', and mistake to create a clear image: a choice so careless it looks like the person did not think at all. That's why it means 'a foolish or careless error'.
