Book location in the library? Shh! One left out (2,3,5)
I believe the answer is:
on the shelf
'book location in the library?' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'shh one left out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'shh'+'one'+'left'='shhoneleft'
'shhoneleft' anagrammed gives 'ON THE SHELF'.
Can you help me to learn more?
(Other definitions for on the shelf that I've seen before include "Where you might find Emma" , "destined never to meet her beau?" , "Book here, perhaps" , "Despairing of a husband" .)
