Book anaesthetists (7)
I believe the answer is:
numbers
This clue could be a double definition.
'book' is the first definition.
(book of the Bible)
'anaesthetists' is the second definition.
Although both the answer and definition are plural nouns, I don't understand how one could define the other.
Can you help me to learn more?
(Other definitions for numbers that I've seen before include "Amounts; counts" , "Figures, digits" , "Amounts; songs, etc" , "Fourth book of the Old Testament" , "quantity" .)
