My man, the French tragic dramatist (9)
I believe the answer is:
corneille
'tragic dramatist' is the definition.
'corneille' can be an answer for 'dramatist' (I've seen this before). I am not certain of the 'tragic' bit.
'my man the french' is the wordplay.
'my' becomes 'cor' (both are expressions of surprise).
'man' becomes 'neil' (man's name).
'the french' becomes 'le' ('the' in French).
'cor'+'neil'+'le'='CORNEILLE'
Can you help me to learn more?
(Other definitions for corneille that I've seen before include "Dramatist" , "Pierre ---, Fr. tragedian" , "French author" , "French writer" .)
