Something owed (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
debt
'something owed' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for debt that I've seen before include "Money or favour owed" , "state of obligation" , "Financial problem?" , "outstanding" , "Amount owed" .)
