Expect chap will get work (4)
I believe the answer is:
hope
'expect' is the definition.
(synonyms)
'chap will get work' is the wordplay.
'chap will' becomes 'he' (I can't justify this - if you can you should believe this answer much more).
'get' is an insertion indicator.
'work' becomes 'op' (abbreviation for opus).
'he' going around 'op' is 'HOPE'.
Can you help me to learn more?
(Other definitions for hope that I've seen before include "Longing" , "The Cape of Good -" , "Companion to faith and charity" , "'. . . . springs eternal in the human breast'" , "One who wrote about prisoner" .)
