Defining character of a person (8)

I believe the answer is:

identity

(Other definitions for identity that I've seen before include "Sameness; selfhood" , "Individuality providing recognition" , "Condition of being a specified person" , "Uniqueness" , "One's individuality" .)

I've seen this clue in The Guardian.
