Book author’s dedication? (4)
I believe the answer is:
tome
This clue could be a double definition.
'book' is the first definition.
(a tome is a book)
'author's dedication?' is the second definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps there's an association between them I don't understand?
Can you help me to learn more?
(Other definitions for tome that I've seen before include "dictionary?" , "Hefty volume" , "War and Peace, say" , "Large scholarly volume" , "A hefty book" .)
