Right do well after Surrey's opener dropped (6)
I believe the answer is:
proper
'right' is the definition.
('proper' can be similar in meaning to 'right')
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for proper that I've seen before include "Correct, decent" , "Genuine; correct" , "Real; genuine" , "Seemly" , "Conventional" .)
