He shelves work done by others (9)
I believe the answer is:
librarian
'he shelves work done by others' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'he' is the wordplay.
I cannot really see how this works, but
'he' could be 'ian' and 'ian' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for librarian that I've seen before include "Custodian of a collection of books" , "employee in Reading office?" , "Browsers need her" , "job!" , "Book keeper" .)
