Golf clubs lacking weight to give advantages (5)
I believe the answer is:
edges
'advantages' is the definition.
(edge is a kind of advantage)
'golf clubs lacking weight' is the wordplay.
'golf clubs' becomes 'wedges' (wedge is a type of golf club).
'lacking' suggests deleting specific letters.
'weight' becomes 'w'.
'wedges' with 'w' taken out is 'EDGES'.
'to give' acts as a link.
(Other definitions for edges that I've seen before include "Slowly moves" , "Outer limits" , "Boundaries of a surface" , "Des, e.g. (anag.)" , "They're used for cutting" .)
