Cure is found by worker for whom I have great affection (8)
I believe the answer is:
antidote
'cure' is the definition.
(I know that antidote is a type of cure)
'by worker for whom i have great affection' is the wordplay.
I cannot really understand how this works, but
'worker' could be 'ant' (worker is a type of ant) and 'ant' is found in the answer.
'i' is within the answer.
'affection' could be 'dote' (I have seen 'Lavish affection' mean 'dote' so perhaps 'affection' could also mean 'dote') and 'dote' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'is found' is the link.
Can you help me to learn more?
(Other definitions for antidote that I've seen before include "Cure for poison" , "simple remedy" , "Counterpoison" , "Counteracting medicine" , "Donate it to anti-poison agent" .)
