Part of a book of verses? (7)
I believe the answer is:
chapter
'part of a book' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for chapter that I've seen before include "Distinctive period of history" , "series of events" , "Division of novel - church body" , "Division of book, usually numbered" , "Sequence - section of book - church body" .)
