Friend consumed flavour (6)
I believe the answer is:
palate
'flavour' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'friend consumed' is the wordplay.
'friend' becomes 'pal' (pal can mean a friend).
'consumed' becomes 'ate' (to eat is to consume food).
'pal'+'ate'='PALATE'
Can you help me to learn more?
(Other definitions for palate that I've seen before include "Sense of taste at roof of mouth" , "relish" , "part of trap" , "One may savour" , "A plate (anag.)" .)
