Nearest point within a wardrobe (7)
I believe the answer is:
closest
'nearest' is the definition.
('close' can be a synonym of 'near')
'point within a wardrobe' is the wordplay.
'point' becomes 'S' (South).
'within' indicates putting letters inside.
'a wardrobe' becomes 'closet' ('closet' can be a synonym of 'wardrobe').
's' going into 'closet' is 'CLOSEST'.
(Other definitions for closest that I've seen before include "Most stuffy" , "Superlatively dense" , "Most secretive" , "Nearest or meanest" , "Most intimate" .)
