Self-centered sort (6)
I believe the answer is:
egoist
'self-centered sort' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for egoist that I've seen before include "Self-seeker" , "Person with very a good opinion of himself" , "Narcissist" , "Selfish type" , "Excessively conceited person" .)
