Accepted as being to the good (4)
I believe the answer is:
took
'accepted' is the definition.
(take can mean to accept something)
'being to the good' is the wordplay.
'being to' becomes 'to'.
'the good' becomes 'ok' ().
'to'+'ok'='TOOK'
'as' acts as a link.
(Other definitions for took that I've seen before include "Gained; stole; made (notes)" , "Purloined" , "Went through" , "Helped oneself to" , "Accepted; guided" .)
