Oriental fighting to finish in knockout (5)
I believe the answer is:
kendo
'oriental fighting' is the definition.
'kendo' can be an answer for 'fighting' (I have seen 'Asian fighting' mean 'kendo' so perhaps 'fighting' could also mean 'kendo'). I am unsure of the 'oriental' bit.
'finish in knockout' is the wordplay.
'finish' becomes 'end' (come to an end).
'in' is an insertion indicator.
'knockout' becomes 'ko' (abbreviation).
'end' going into 'ko' is 'KENDO'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for kendo that I've seen before include "Fighting in Japan" , "Martial art involving stick fighting" , "wooden fencing?" , "discipline" , "Asian fighting" .)
