Name hospital hiding large sum paid to church (5)
I believe the answer is:
tithe
'large sum paid to church' is the definition.
I can't judge whether this definition defines the answer.
'name hospital hiding' is the wordplay.
'name' becomes 'tite' (I can't justify this - if you can you should believe this answer much more).
'hospital' becomes 'H' (abbreviation for hospital).
'hiding' is an insertion indicator.
'tite' enclosing 'h' is 'TITHE'.
Can you help me to learn more?
(Other definitions for tithe that I've seen before include "10% tax" , "Ancient tax" , "Tax once levied" , "Tax paid to church" , "One-tenth; church tax" .)
