Church area where Jack has to doff his cap (4)
I believe the answer is:
nave
'church area' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for nave that I've seen before include "Central place in church" , "Main body of a church" , "Part of a church sounds roguish" , "Part of the church sounds like a rogue" , "Main part of a church" .)
