Determined to make a contribution to the match (3)
I believe the answer is:
set
'determined' is the definition.
(similar in meaning)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for set that I've seen before include "Complete collection" , "Gel; start (a fire)" , "Fix; lay" , "Gel; group" , "several games" .)
