Division of church in ten parts roughly (8)
I believe the answer is:
transept
'division of church' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'ten parts roughly' is the wordplay.
'roughly' indicates an anagram.
'ten'+'parts'='tenparts'
'tenparts' with letters rearranged gives 'TRANSEPT'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for transept that I've seen before include "Wing of cross-shaped church" , "always running north to south" , "Crossing part of a church" , "Side part of a church" , "Part of church intersecting nave" .)
