Finally doesn't finish a volume (5)
I believe the answer is:
atlas
'a volume' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'finally doesn't finish' is the wordplay.
'finally' becomes 'at last' (synonyms).
'doesn't finish' means to remove the last letter.
'atlast' with its final letter taken away is 'ATLAS'.
Can you help me to learn more?
(Other definitions for atlas that I've seen before include "Sky carrier - map book" , "African mountain range" , "Book of geography" , "One hugely burdened" , "N African mountains - seemaps book" .)
