Modern poetry Macron translated (12)
I believe the answer is:
contemporary
'modern' is the definition.
(similar in meaning)
'poetry macron translated' is the wordplay.
'translated' is an anagram indicator.
'poetry'+'macron'='poetrymacron'
'poetrymacron' anagrammed gives 'CONTEMPORARY'.
(Other definitions for contemporary that I've seen before include "Modern in style or design" , "current" .)
