Bread crusts on dole? That’s rejected by my employer! (6)
I believe the answer is:
editor
'my employer' is the definition.
I can't tell whether this definition defines the answer.
'bread crusts on dole? that's rejected' is the wordplay.
'bread' becomes 'roti' (roti is a type of bread).
'crusts on dole?' becomes 'de' (I can't explain this - if you can you should give a lot more credence to this answer).
'that's rejected' shows that the letters should be reversed in order.
'roti'+'de'='rotide'
'rotide' back-to-front is 'EDITOR'.
'by' is the link.
Can you help me to learn more?
(Other definitions for editor that I've seen before include "One who revises another's writing" , "Rag worker" , "Reviser" , "Redo it and become head of publication" , "Journalist in charge of publication" .)
