Tenor in touch, perhaps (5)
I believe the answer is:
sense
I believe this clue is a double definition.
'tenor' is the first definition.
(thesaurus)
'touch perhaps' is the second definition.
(touch is a kind of sense)
'in' is the link.
(Other definitions for sense that I've seen before include "Feeling - reason" , "Understand" , "A particular meaning" , "Suspect" , "Divine" .)
