'epic' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?

'ego is out to steal foreign money' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'to steal' is an insertion indicator.
'foreign money' becomes 'rand' (currency of South Africa).
'ego'+'is'='egois'
'egois' with letters rearranged gives 'giose'.
'giose' enclosing 'rand' is 'GRANDIOSE'.
