Patron’s complaint involving new player (12)
I believe the answer is:
benefactress
'patron's' is the definition.
(thesaurus)
'complaint involving new player' is the wordplay.
I cannot quite see how this works, but
'new' could be 'n' (abbreviation as in New Testament NT) and 'n' is located in the answer.
'complaint' could be 'beef' (beef can mean a complaint or objection) and 'beef' is found in the remaining letters.
'player' could be 'actress' (actress is a kind of player) and 'actress' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for benefactress that I've seen before include "Donor, patron" , "One gives" , "Generous woman" , "She provides financial support" , "one who does good" .)
