Be more clever than a chump at Oxford University? (6)
I believe the answer is:
outwit
'be more clever' is the definition.
I can't judge whether this definition defines the answer.
'a chump at oxford university?' is the wordplay.
'a chump' becomes 'twit' (I can't justify this - if you can you should give a lot more credence to this answer).
'at' is a charade indicator (letters next to each other) (I've seen this in other clues).
'oxford university?' becomes 'OU'.
'twit' put after 'ou' is 'OUTWIT'.
'than' acts as a link.
Can you help me to learn more?
(Other definitions for outwit that I've seen before include "Get the better of by being smarter" , "Intellectually get the better of" , "To fox" , "Outfox" , "Surpass in ingenuity" .)
