Surface Forms

flea-brained positive

Morphology

flea-brained = brained (semi-transparent) = flea + brain + ed

The immediate base 'brained' is the adjectival form of 'brain' and combines with 'flea' metaphorically; the relation is inferable but somewhat idiomatic.

Etymology

Flea-brained comes from the image of a flea, a very small, jumpy insect, plus brain, so it suggests a 'small' or 'jumpy' mind. That's why flea-brained means having silly ideas or not being serious.
