Part of book showing group of clergymen (7)
I believe the answer is:
chapter
'part of book' is the definition.
(many books contain chapters)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for chapter that I've seen before include "Division of written work" , "one section of book" , "Book division - assembly of canons" , "series of events" , "Part of book" .)
