Feeling a nose isn't out of joint (9)
I believe the answer is:
'feeling' is the definition.
(sensation is a kind of feeling)
'a nose isn't out of joint' is the wordplay.
'out of joint' indicates anagramming the letters.
'anoseisnt' anagrammed gives 'SENSATION'.
(Other definitions for sensation that I've seen before include "Scandal" , "Physical feeling or perception" , "Feeling produced by stimulation, or dramatic news (9)" , "Feeling; thrilling person or thing" , "Crowd puller" .)
