The garment being worn has taste! (5)
I believe the answer is:
macon
'taste' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'the garment being worn' is the wordplay.
'the garment' becomes 'mac' (mac is a kind of garment).
'being worn' becomes 'on'.
'mac'+'on'='MACON'
'has' acts as a link.
Can you help me to learn more?
(Other definitions for macon that I've seen before include "Wandering (knight)" , "Variety of Burgundy" , "Dry white Burgundy wine" , "French wine district" , "Drink" .)
