Morphology

cockbrained + mistake

The adjective 'cockbrained' is an archaic/idiomatic formation whose meaning 'foolish' is not transparently derived from literal constituents 'cock' (a rooster) and 'brained' (related to brain). The compound is rare and not built from a productive, cross-linguistically obvious pattern, so a B1 learner who knows the parts would unlikely infer the idiomatic sense without prior exposure.

Etymology

Cockbrained mistake may come from the picture of a rooster (cock) acting loud and silly instead of thinking clearly. If an idea is 'cockbrained' it is a silly idea that was not well thought, so a cockbrained mistake means a foolish error.
