Predicament consuming terribly wary dramatist (10)
I believe the answer is:
playwright
'dramatist' is the definition.
('playwright' can be a synonym of 'dramatist')
'predicament consuming terribly wary' is the wordplay.
'predicament' becomes 'plight' ('plight' can be a synonym of 'predicament').
'consuming' indicates putting letters inside.
'terribly' is an anagram indicator.
'wary' with letters rearranged gives 'aywr'.
'plight' placed around 'aywr' is 'PLAYWRIGHT'.
(Other definitions for playwright that I've seen before include "16 dn of dramas" , "Will, say" , "Coward, possibly" , "Author of dramas" , "Dramatist" .)
