KO'd, punching through about twice -- try another way (7)
I believe the answer is:
reroute
'ko'd punching through about twice try' is the definition.
I can't judge whether this defines the answer.
'another way' is the wordplay.
'another' becomes 're' (I've seen this in other clues).
'way' becomes 'route' (route is a kind of way**).
're'+'route'='REROUTE'
Can you help me to learn more?
(Other definitions for reroute that I've seen before include "Send elsewhere" , "Divert" , "Send another way" , "Change directions" , "Send in alternative direction" .)
