The roof of the mouth (6)
I believe the answer is:
palate
'the roof of the mouth' is the definition.
(synonyms)
This is the entire clue.
(Other definitions for palate that I've seen before include "A plate (anag.)" , "where taste is considered" , "Roof of the mouth, seat of taste" , "Sense of taste at roof of mouth" , "One may savour" .)
