For example ring me (3)
I believe the answer is:
ego
'me' is the definition.
(thesaurus)
'for example ring' is the wordplay.
'for example' becomes 'eg' ('e.g.' can be a synonym of 'for example').
'ring' becomes 'o'.
'eg'+'o'='EGO'
(Other definitions for ego that I've seen before include "Aspect of the personality" , "One's image of oneself" , "One's sense of self-importance" , "Personal pride" , "number one" .)
