Playwright represented in our Museum of Literature before (7)
I believe the answer is:
moliere
'playwright' is the definition.
(I know that Moliere is a playwright)
'represented in our museum of literature before' is the wordplay.
I cannot quite see how this works, but
'of' could be 'o' and 'o' is found in the answer.
'before' could be 'ere' (poetic term) and 'ere' is found in the answer.
The remaining letters 'mli' 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 moliere that I've seen before include "French writer" , "C17 French playwright (Le Misanthrope)" , "17th century French playwright" , "Fr. dramatist (Tartuffe)" , "French playwright (Tartuffe)" .)
