A female - feeble or on fire? (6)
I believe the answer is:
aflame
'on fire?' is the definition.
('aflame' can be a synonym of 'on fire')
'a female feeble' is the wordplay.
'a female' becomes 'af' (I've seen this in other clues).
'feeble' becomes 'lame' ('lame' can be a synonym of 'feeble').
'af'+'lame'='AFLAME'
'or' is the link.
(Other definitions for aflame that I've seen before include "Ardent" , "Deeply aroused" , "On fire" , "Ma, flea could be burning" , "very hot" .)
