Something amusing for Maggie's hat, a feather fan (8)
I believe the answer is:
twitcher
'amusing for maggie's hat a feather fan' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'something' is the wordplay.
I cannot quite understand how this works, but
'something' could be 'er' (I've seen this in other clues) and 'er' is located in the answer.
The remaining letters 'twitch' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for twitcher that I've seen before include "Bird watcher" , "Rare bird spotter" , "Name for a keen bird-watcher" , "Spasmodic" , "Nervous person" .)
