Manage to get point of letter (4)
I believe the answer is:
rune
'letter' is the definition.
(I know that rune is a type of letter)
'manage to get point' is the wordplay.
'manage' becomes 'run' (both can mean to organise).
'to get' says to put letters next to each other.
'point' becomes 'e' (compass point).
'run'+'e'='RUNE'
'of' is the link.
(Other definitions for rune that I've seen before include "Ancient symbol" , "Old Scandinavian letter" , "Old alphabet letter" , "Mystic symbol" , "Ancient character" .)
