Taste and smell (6)
I believe the answer is:
senses
'taste and smell' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for senses that I've seen before include "The body has five of them" , "Faculties for experiencing the world" , "Sight, touch etc." , "Feels intuitively" , "We have five, though some claim six" .)
