Flighty fellows? (6)
I believe the answer is:
airmen
'flighty fellows?' is the definition.
The answer and definition can be both people as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'flighty fellows?' is the wordplay.
'flighty' becomes 'air' (I can't justify this - if you can you should give a lot more credence to this answer).
'fellows?' becomes 'men' (fellow can mean a man).
'air'+'men'='AIRMEN'
Can you help me to learn more?
(Other definitions for airmen that I've seen before include "Red Arrows" , "Those flying" , "Male aviators" , "they take off from the ground" , "Chaps needing to take off" .)
