Bird with an eminent person (5)
I believe the answer is:
titan
'eminent person' is the definition.
'titan' can be an answer for 'person' (titan is a kind of person). I am not certain of the 'eminent' bit.
'bird with an' is the wordplay.
'bird' becomes 'tit' (tit is a kind of bird).
'with' is a charade indicator (letters next to each other).
'tit'+'an'='TITAN'
Can you help me to learn more?
(Other definitions for titan that I've seen before include "Largest satellite of Saturn" , "Person of great importance" , "Taint in old Greek god" , "One of the mythological Greek giants who ruled the world" , "Moon of Saturn visited by the Huygens probe" .)
