Central area of a church (4)
I believe the answer is:
nave
'central area of a church' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for nave that I've seen before include "Part of the church sounds like a rogue" , "The hub of a wheel, or body of church" , "Central space in church" , "Take no risks" , "Middle of wheel" .)
