European with energy and self-confidence (3)
I believe the answer is:
ego
'self-confidence' is the definition.
(I've seen this in another clue)
'european with energy' is the wordplay.
'european' becomes 'E' (abbreviation e.g. EU).
'with' is a charade indicator (letters next to each other).
'energy' becomes 'go' (I've seen this in other clues).
'e'+'go'='EGO'
'and' is the link.
(Other definitions for ego that I've seen before include "Sense of self, conceit" , "Selfishness" , "Person's sense of self" , "Self-esteem, sense of self" , "Inner self" .)
