One is owed 100 rupees by magazine boss (8)
I believe the answer is:
creditor
'one is owed' is the definition.
I can't tell whether this defines the answer.
'100 rupees by magazine boss' is the wordplay.
'100' becomes 'C' (Roman numeral).
'rupees' becomes 'r' (abbreviation for rupees).
'by' is a charade indicator (letters next to each other).
'magazine boss' becomes 'editor' (I've seen this in another clue).
'c'+'r'+'editor'='CREDITOR'
Can you help me to learn more?
(Other definitions for creditor that I've seen before include "one to whom money is due" , "One who's owed money" , "recipient of money" , "to whom something is due" , "Person to whom debt is owed" .)
