featherbrain
Airheaded, flighty person
A featherbrain is a scatterbrained or frivolous person—someone whose head seems filled with feathers rather than substance.
The word is mildly dismissive rather than harsh: Don't be such a featherbrain; focus!
The adjective featherbrained describes the quality: another featherbrained scheme.
