Recognition for good exam result (6)
I believe the answer is:
credit
'recognition' is the definition.
(synonyms)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for credit that I've seen before include "Reputation (for solvency)" , "Time to pay, or due recognition" , "Belief; tick" , "Honour or reliability - believe" , "Believe the time allowed for payment" .)
