A sense of spectacle (5)
I believe the answer is:
sight
This clue is a double definition.
'a sense' is the first definition.
(sight or vision is a sense)
'spectacle' is the second definition.
(spectacle can mean a sight or display)
'of' is the link.
(Other definitions for sight that I've seen before include "Power of vision" , "something ugly" , "Spectacle; aiming aid" , "Sense" , "View" .)
