Banned a poet, reportedly (6)
I believe the answer is:
barred
'banned' is the definition.
(thesaurus)
'a poet reportedly' is the wordplay.
'a poet' becomes 'bard' (bard is a kind of poet).
'reportedly' indicates a 'sounds like' (homophone) clue.
'bard' sounds like 'BARRED'.
(Other definitions for barred that I've seen before include "Prohibited" , "Wouldn't allow" , "Refused access to, say pub" , "Refused entry to local pub" , "Precluded, obstructed" .)
