Manage range needing no introduction (4)
I believe the answer is:
cope
'manage' is the definition.
('cope' can be a synonym of 'manage')
'range needing no introduction' is the wordplay.
'range' becomes 'scope' ('scope' can be a synonym of 'range').
'needing no introduction' means to remove the first letter.
'scope' with its first letter taken away is 'COPE'.
(Other definitions for cope that I've seen before include "Join" , "Deal effectively (with a difficulty)" , "Long cloak for a priest" , "Manage - poet, first name 18" , "Priest's ceremonial cloak" .)
