New or reinstalled proprietor? (5)
I believe the answer is:
owner
'proprietor?' is the definition.
(I know that proprietor can be written as owner)
'new or reinstalled' is the wordplay.
'new or' anagrams to 'OWNER'.
However, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for owner that I've seen before include "The one in lawful possession" , "Legal possessor" , "The person in legal possession" , "Man of property" , "Title-holder" .)
