No part in play for angel? (6)
I believe the answer is:
patron
'angel?' is the definition.
(an angel is a financial backer)
'no part in play' is the wordplay.
'in play' indicates anagramming the letters.
'no'+'part'='nopart'
'nopart' with letters rearranged gives 'PATRON'.
'for' is the link.
(Other definitions for patron that I've seen before include "Sponsor or backer as of the arts" , "Regular customer; backer" , "Restaurant customer" , "manager (13) [FRENCH]" , "Pot ran out for protector" .)
