Story books plugged by a keeper of books (10)
I believe the answer is:
accountant
'keeper of books' 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?
'story books plugged by a' is the wordplay.
'story' becomes 'account' (synonyms).
'books' becomes 'NT' (New Testament).
'plugged by' is an insertion indicator (plug can mean to block up a gap).
'account'+'nt'='accountnt'
'accountnt' placed around 'a' is 'ACCOUNTANT'.
Can you help me to learn more?
(Other definitions for accountant that I've seen before include "auditor" , "One keeping track of money" , "One dealing with finances" , "Financial expert" , "financial controller" .)
