Plume of my aunt perhaps following exploit (7)
I believe the answer is:
feather
'plume' is the definition.
(I know that plume can be written as feather)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for feather that I've seen before include "'Birds of a . . . . . . . flock together'" , "Rotate (propeller) blades (to reduce thrust)" , "thing of little importance" , "dance step" , "In your cap, it's an accomplishment" .)
