Brussels rent that is reduced for playwright (9)
I believe the answer is:
euripides
'for playwright' is the definition.
(I've seen this before)
'brussels rent that is reduced' is the wordplay.
'brussels' becomes 'EU' (European Parliament is based in Brussels).
'rent' becomes 'rip' (rent can mean a tear in something).
'that is' becomes 'id est' ('that is' in Latin).
'reduced' means to remove the last letter.
'idest' with its last letter taken off is 'ides'.
'eu'+'rip'+'ides'='EURIPIDES'
(Other definitions for euripides that I've seen before include "old playwright" , "Athenian playwright" , "Classical Greek dramatist" , "Greek dramatist - rise up, die (anag)" , "He made drama" .)
