Accountant or librarian? (10)
I believe the answer is:
bookkeeper
I believe this is a double definition.
'accountant' is the first definition.
(I know that bookkeeper is a type of accountant)
'librarian?' is the second definition.
(thesaurus)
'or' acts as a link.
(Other definitions for bookkeeper that I've seen before include "Accounts official" , "Business occupation" , "person responsible for financial oversight" , "who works to maintain balance" , "accountant" .)
