Supporter with complaint about new player (10)
I believe the answer is:
benefactor
'supporter' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'complaint about new player' is the wordplay.
'complaint' becomes 'beef' (beef can mean a complaint or objection).
'about' indicates putting letters inside.
'new' becomes 'n' (abbreviation as in New Testament NT).
'player' becomes 'actor' (synonyms).
'beef' going around 'n' is 'benef'.
'benef'+'actor'='BENEFACTOR'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for benefactor that I've seen before include "Person giving to a good cause" , "One giving money to person/cause" , "One giving to worthy cause" , "Patronising sort" , "One financially supporting a worthy cause" .)
