Manage to find eastern symbol (4)
I believe the answer is:
rune
'symbol' is the definition.
(rune is a kind of symbol)
'manage to find eastern' is the wordplay.
'manage' becomes 'run' (both can mean to organise).
'to find' means one lot of letters go next to another.
'eastern' becomes 'e'.
'run'+'e'='RUNE'
(Other definitions for rune that I've seen before include "Mystical symbol" , "Ancient symbol" , "Spell" , "Mystic symbol" , "Mysterious character" .)
