Member welcomed by man -- top, say? (7)
I believe the answer is:
garment
'top say?' is the definition.
(I know that top is a type of garment)
'member welcomed by man' is the wordplay.
'member' becomes 'arm' (member can mean a limb).
'welcomed by' indicates putting letters inside (letters welcomed inside).
'man' becomes 'gent' (gent is a kind of man).
'arm' put into 'gent' is 'GARMENT'.
(Other definitions for garment that I've seen before include "Singular outfit" , "An article of clothing (7)" , "Something put on" , "Grant me (anag.)" , "coat maybe" .)
