Yearning for combat sport (3,2,3)
I believe the answer is:
tug of war
This clue could be a double definition.
'yearning for combat' is the first definition.
'tug-of-war' can be an answer for 'combat' (thesaurus). I am not certain of the 'yearning for' bit.
'sport' is the second definition.
(thesaurus)
Can you help me to learn more?
(Other definitions for tug of war that I've seen before include "Long, hard struggle between groups" , "Traditional field contest" , "Pulling contest" , "Battle-ship" , "Sport that uses a rope" .)
