Morphology

cockbrained + idea

The adjective 'cockbrained' is a metaphorical composition of 'cock' + 'brained' that could suggest a foolish or ill‑judged mind, so a learner who knows the constituents might infer a sense of foolishness. However the term is archaic/rare and the metaphorical mapping (why a 'cock' implies foolishness) is not a productive, cross‑linguistic pattern, so its precise sense is not reliably predictable for a B1 learner without prior exposure.

Etymology

The phrase cockbrained idea may come from the image of a rooster (a cock) tilting its head, so the brained part suggests a twisted or wrong head. So a cockbrained idea means a 'foolish' or silly plan.
