Female making a firm point (3)
I believe the answer is:
cow
'female' is the definition.
(I've seen this before)
'a firm point' is the wordplay.
'a firm' becomes 'co' (a firm is a company).
'point' becomes 'w' (W is an example**).
'co'+'w'='COW'
'making' acts as a link.
(Other definitions for cow that I've seen before include "Subdue in bovine manner?" , "Bovine female" , "Female seal" , "Female domestic animal" , "Female farm animal" .)
