Sneak exiting card game left with golden award (13)
I believe the answer is:
baccalaureate
'award' is the definition.
(baccalaureate is a kind of award)
'sneak exiting card game left with golden' is the wordplay.
I cannot really understand how this works, but
'left' could be 'l' (common abbreviation) and 'l' is located in the answer.
'golden' could be 'aureate' (synonyms) and 'aureate' is found in the answer.
The remaining letters 'bacca' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for baccalaureate that I've seen before include "International alternative to A level" , "Type of degree" , "Educational qualification" , "test result" , "academic qualification" .)
