Woman being different, I gathered (5)
I believe the answer is:
elsie
'woman' is the definition.
'different i gathered' is the wordplay.
'different' becomes 'else' (synonyms).
'gathered' is an insertion indicator.
'else' enclosing 'i' is 'ELSIE'.
'being' acts as a link.
(Other definitions for elsie that I've seen before include "Name for girl" , "Female name; rhymes with London football team" , "Girl's name" , "Lady" , "woman" .)
