Many ways to show feeling (5)
I believe the answer is:
sense
'feeling' is the definition.
(feeling can mean a sensation)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for sense that I've seen before include "Sat lazily; hung loosely" , "reasonable" , "experience" , "Gumption -- feeling" , "Become aware of" .)
