Touch in a sense (5)
I believe the answer is:
sight
I believe this clue is a double definition.
'touch' is the first definition.
(thesaurus)
'a sense' is the second definition.
(sight is a kind of sense)
'in' is the link.
(Other definitions for sight that I've seen before include "Vista" , "Glimpse" , "Sense" , "good deal" , "View" .)
