Crossword Genius

For example, a rounded figure and personality (3)

Ross

I believe the answer is:

ego

I'm a little stuck... Click here to teach me more about this clue!

'personality' is the definition.
(I've seen this in another clue)

'for example a rounded figure' is the wordplay.
'for example' becomes 'e.g.' (short for 'exempli gratia', 'for example' in Latin).
'a rounded figure' becomes 'o' (I can't justify this - if you can you should believe this answer much more).
'eg'+'o'='EGO'

'and' acts as a link.

Can you help me to learn more?

(Other definitions for ego that I've seen before include "One's self-image" , "One's image of oneself" , "Sense of identity" , "Self-confidence" , "In Virgil I" .)
