Self-image (3)
I believe the answer is:
ego
I believe this is a double definition.
'self' is the first definition.
(synonyms)
'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 "Part of the mind" , "number one" , "Aspect of the personality" , "See 21 Down" , "(Person's) sense of self-esteem" .)
