Women change, becoming male (6)
I believe the answer is:
walter
'male' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see a link between them that I don't see?
'women change' is the wordplay.
'women' becomes 'w' (standard abbreviation).
'change' becomes 'alter' (synonyms).
'w'+'alter'='WALTER'
'becoming' is the link.
Can you help me to learn more?
(Other definitions for walter that I've seen before include "Sir - - Raleigh" , "- Mitty, Thurber's fantasist" , "Elizabethan navigator" , "Sir - Scott; - de la Mare" , "Bruno --;-- Mitty" .)
