New prayer for church body (4)
I believe the answer is:
nave
'church body' is the definition.
(I've seen this in other clues)
'new prayer' is the wordplay.
'new' becomes 'n'.
'prayer' becomes 'ave' (I've seen this in other clues).
'n'+'ave'='NAVE'
'for' is the link.
(Other definitions for nave that I've seen before include "Main body of a church" , "The hub of a wheel, or body of church" , "Central area in a church" , "Central place in church" , "Central part of church" .)
