Manage with English symbol (4)
I believe the answer is:
rune
'symbol' is the definition.
(I know that rune is a type of character)
'manage with english' is the wordplay.
'manage' becomes 'run' (both can mean to organise).
'with' is a charade indicator (letters next to each other).
'english' becomes 'e' (abbreviation).
'run'+'e'='RUNE'
(Other definitions for rune that I've seen before include "Spell" , "Mystical symbol" , "Old Scandinavian letter" , "Ancient character" , "Early symbol used in carvings" .)
