Run the second edition (6)
I believe the answer is:
sprint
'run' is the definition.
(I know that sprint is a more specific form of the action run)
'second edition' is the wordplay.
I cannot really see how this works, but
'second' could be 's' (common abbreviation) and 's' is located in the answer.
The remaining letters 'print' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'the' acts as a link.
Can you help me to learn more?
(Other definitions for sprint that I've seen before include "Run quickly" , "To make fast progress" , "Short race at full speed" , "quick run" , "Quick dash" .)
