Wish fellow would get work (4)
I believe the answer is:
hope
'wish' is the definition.
(I know that hope is a more specific form of the action the wish)
'fellow would get work' is the wordplay.
I cannot quite understand how this works, but
'work' could be 'op' (abbreviation for opus) and 'op' is found within the answer.
'fellow' could be 'he' ('he' refers to a man) and 'he' is present in the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for hope that I've seen before include "Trust" , "One who wrote about prisoner" , "writer" , "Companion to faith and charity" , "virtue he needs?" .)
