Women excluded from golf club side (4)
I believe the answer is:
edge
'side' is the definition.
(edge is a kind of side)
'women excluded from golf club' is the wordplay.
'women' becomes 'w'.
'excluded from' indicates named letters should be taken away.
'golf club' becomes 'wedge' (I've seen this before).
'wedge' with 'w' taken away is 'EDGE'.
(Other definitions for edge that I've seen before include "Side, brink" , "incisiveness" , "Brim" , "Keenness" , "Inch; border" .)
