Minstrel barred from being heard? (4)
I believe the answer is:
bard
'minstrel' is the definition.
(thesaurus)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for bard that I've seen before include "A lyric poet" , "Poet; sounds like forbidden" , "A drab sort of old poet" , "Traditional poet" , "Celtic poet" .)
