Morphology

crackbrained = crackbrain (opaque) = crack + brain + ed

The term 'crackbrain' is not a standard English word, and the meaning of 'crackbrained' is not directly derivable from its components.

Etymology

The word crackbrained comes from the parts crack ('cracked' or 'broken') and brain ('mind' or 'head'), painting a picture of a 'broken mind'. So to call an idea or person crackbrained is to say they are foolish or not sensible.
