Determined to get everything needed (3)
I believe the answer is:
set
'determined' is the definition.
(I know that determined can be written as set)
I cannot 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 "carriage" , "group usually found together" , "become firm" , "Put down the tennis group" , "Solidify like jelly" .)
