Devise fine trophy for orators (5,2)
I believe the answer is:
think up
'devise' is the definition.
(synonyms)
'fine trophy for orators' is the wordplay.
I cannot quite understand how this works, but
'fine' could be 'thin' (similar in meaning) and 'thin' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for think up that I've seen before include "Form in the mind" , "Conceive" .)
