Left work by editor, made strides (5)
I believe the answer is:
loped
'made strides' is the definition.
(to lope is to stride around)
'left work by editor' is the wordplay.
I cannot really understand how this works, but
'left' could be 'l' (common abbreviation) and 'l' is found within the answer.
'work' could be 'op' (abbreviation for opus) and 'op' is found within the answer.
'editor' could be 'ed' and 'ed' is located in the answer.
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 loped that I've seen before include "Ran easily" , "Made strides" , "Ran with long strides" , "Walked with a long bounding stride" , "Walked with long strides" .)
