Comedian missing two days in combat (5)
I believe the answer is:
kendo
'combat' is the definition.
(I've seen this before)
'comedian missing two days' is the wordplay.
I cannot really see how this works, but
'days' could be 'd' (abbreviation for days) and 'd' is located in the answer.
The remaining letters 'keno' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for kendo that I've seen before include "Japanese form of fencing" , "Fighting in Japan" , "Jap. fencing with staves" , "Japanese martial art using split bamboo swords" , "Martial art involving stick fighting" .)
