End debit arrangement, owing (8)
I believe the answer is:
indebted
'owing' is the definition.
(thesaurus)
'end debit arrangement' is the wordplay.
'arrangement' is an anagram indicator.
'end'+'debit'='enddebit'
'enddebit' anagrammed gives 'INDEBTED'.
(Other definitions for indebted that I've seen before include "Owing gratitude to another for help" , "Grateful" , "Obligated" , "Owing money, gratitude" , "Under obligation to, for loan or favour" .)
