Morphology
airbrain + idea
The form 'airbrain' is not a conventional dictionary headword, though English has related idioms like 'airheaded'/'airhead' where 'air' implies emptiness and 'brain' relates to thinking. A B1 learner who knows 'air' and 'brain' might partly infer 'a silly or empty-minded idea' but this inference depends on familiarity with the idiomatic use of 'air-', so the meaning is only partly predictable.
Etymology
Airbrain idea may come from the picture of someone's head filled with air instead of a real brain, so their thoughts are light and float away like a balloon. That's why an airbrain idea means 'a silly or impractical thought'.
