Image (4)
'image' is the definition.
(I know that image can be written as icon)
This is all the clue.
(Other definitions for icon that I've seen before include "found on computer screen" , "portrait" , "Image or representation" , "Someone uncritically admired" , "Sprites" .)
(Other definitions for self that I've seen before include "One's individuality" , "Person's distinct identity" , "one's identity" , "Will the writer?" , "Will the author" .)
