Originality (7)
I believe the answer is:
novelty
'originality' is the definition.
(I know that novelty is a type of originality)
This is all the clue.
(Other definitions for novelty that I've seen before include "Freshness" , "Small, cheap ornament" , "Originality" , "Small, inexpensive, unusual article" , "Something new and strange" .)
