Taste or touch (5)
I believe the answer is:
sense
This clue is a double definition.
'taste' is the first definition.
(thesaurus)
'touch' is the second definition.
(I have seen 'eg Touch ' mean 'sense' so perhaps 'touch' could also mean 'sense')
(Other definitions for sense that I've seen before include "eg Vision, hearing" , "Hearing maybe" , "Realistic attitude" , "Comprehend" , "experience" .)
