Shark, clever, cleaned out newspaper boss (8)
I believe the answer is:
'shark' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'clever cleaned out newspaper boss' is the wordplay.
'cleaned out' suggests removing the centre.
'newspaper boss' becomes 'editor' (newspaper editor).
'clever' with its centre taken out is 'cr'.
Can you help me to learn more?
(Other definitions for creditor that I've seen before include "Moneylender" , "to whom something is due" , "He should be paid" , "Person owed money by director" , "Person to whom money isowed" .)
