Inflated self-image (3)
I believe the answer is:
ego
This clue is a double definition.
'inflated self' is the first definition.
(I've seen this in another clue)
'image' is the second definition.
(I have seen 'Image of oneself ' mean 'ego' so perhaps 'image' could also mean 'ego')
(Other definitions for ego that I've seen before include "Conscious self" , "Vowel to disappear, < say another" , "Aspect of the personality" , "Sense of self, conceit" , "Inflated pride" .)
