Feeling of excitement (6)
I believe the answer is:
thrill
'feeling of excitement' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for thrill that I've seen before include "Almost pleasurable sensation of fright" , "Excited feeling" , "Tingling feeling of excitement" , "Intense feeling of delight or excitement" , "bring a tingle of excitement" .)
