Work repelled poet having no English (4)
I believe the answer is:
toil
'work' is the definition.
(toiling is a kind of working)
'repelled poet having no english' is the wordplay.
'repelled' shows that the letters should be reversed in order.
'poet' becomes 'Eliot' (TS Eliot).
'having no' is a deletion indicator.
'english' becomes 'E' (abbreviation).
'eliot' with 'e' taken out is 'liot'.
'liot' back-to-front is 'TOIL'.
(Other definitions for toil that I've seen before include "Work incessantly" , "Manual labour" , "Work hard and long" , "Work hard, labour" , "Drudgery" .)
