Permitted everyone to be a creditor (7)
I believe the answer is:
allowed
'permitted' is the definition.
('allow' can be a synonym of 'permit')
'everyone to be a creditor' is the wordplay.
'everyone' becomes 'all' (all people).
'to be a creditor' becomes 'owed' (I am not sure about this - if you are sure you should believe this answer much more).
'all'+'owed'='ALLOWED'
Can you help me to learn more?
(Other definitions for allowed that I've seen before include "Gave permission" , "Permitted and granted" , "Owned" , "Acknowledged" , "Legitimate" .)
