Female, an ardent supporter (3)
I believe the answer is:
fan
'ardent supporter' is the definition.
'fan' can be an answer for 'supporter' (fan is a kind of supporter). I'm unsure of the 'ardent' bit.
'female an' is the wordplay.
'female' becomes 'f' (common abbreviation).
'f'+'an'='FAN'
Can you help me to learn more?
(Other definitions for fan that I've seen before include "Cooling device or disciple of performer" , "Device to cool the face" , "Aficionado" , "Keen follower; cooler" , "Devotee; ventilator" .)
