The last page of the novel found on the shelf in the library (4,3)
I believe the answer is:
book end
'shelf in the library' is the definition.
The definition suggests a singular noun which matches the answer.
'the last page of the novel found on' is the wordplay.
'the last' becomes 'end' (I've seen this in another clue).
'page of the novel' becomes 'book' (I can't explain this - if you can you should believe this answer much more).
'found on' says to put letters next to each other.
'end' after 'book' is 'BOOK-END'.
'the' is the link.
Can you help me to learn more?
(Another definition for book end that I've seen is " Library shelf support".)
