Payment method that could make Rodney more confused
I believe the answer is:
money order
'payment method that could' is the definition.
The definition and answer can be both related to property as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'rodney more confused' is the wordplay.
'confused' indicates an anagram.
'rodney'+'more'='rodneymore'
'rodneymore' anagrammed gives 'MONEY-ORDER'.
'make' is the link.
Can you help me to learn more?
(Other definitions for money order that I've seen before include "Means to pay" , "way to make payment?" .)
