Nothing in translation of the Bard is coarse (5)
I believe the answer is:
broad
'coarse' is the definition.
(thesaurus)
'nothing in translation of the bard' is the wordplay.
'nothing' becomes 'O' (looks like zero - 0).
'in' indicates putting letters inside.
'translation of' indicates anagramming the letters (translate can mean to transform).
'bard' anagrammed gives 'brad'.
'o' put within 'brad' is 'BROAD'.
'is' acts as a link.
(Other definitions for broad that I've seen before include "Board (anag.)" , "Wide; general" , "River expansion" , "Without detail; wide" , "Open" .)
