Relish; discernment (5)
I believe the answer is:
taste
This clue is a double definition.
'relish' is the first definition.
(I've seen this in another clue)
'discernment' is the second definition.
(I know that discernment can be written as taste)
(Other definitions for taste that I've seen before include "one of the 4 [SENSE] s" , "Brief sample; discernment" , "Partake of" , "Small portion" , "Little bit" .)
