Dish has a flavour (6)
I believe the answer is:
palate
'flavour' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'dish has a' is the wordplay.
'dish' becomes 'plate' (plate is a kind of dish).
'has' is an insertion indicator.
'plate' placed around 'a' is 'PALATE'.
Can you help me to learn more?
(Other definitions for palate that I've seen before include "where taste is considered" , "having ability to appreciate good food" , "A plate (anag.)" , "One may savour" , "Roof of the mouth, seat of taste" .)
