Prince Andrew possibly owing around a thousand (4)
I believe the answer is:
duke
'prince andrew' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'owing around a thousand' is the wordplay.
'owing' becomes 'due' (similar in meaning).
'around' indicates putting letters inside.
'a thousand' becomes 'K' (K can mean thousand, e.g. 10k).
'due' enclosing 'k' is 'DUKE'.
'possibly' acts as a link.
Can you help me to learn more?
(Other definitions for duke that I've seen before include "Lord" , "- - Ellington (jazz musician)" , "Highest rank of British peer" , "Highest-ranking nobleman" , "Nickname of John Wayne" .)
