Shakespeare reportedly not allowed (6)
I believe the answer is:
barred
'not allowed' is the definition.
The answer and definition can be both to do with communicating as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'shakespeare reportedly' is the wordplay.
'shakespeare' becomes 'bard' (Shakespeare is known as the Bard).
'reportedly' indicates a 'sounds like' (homophone) clue.
'bard' sounds like 'BARRED'.
Can you help me to learn more?
(Other definitions for barred that I've seen before include "Excluded, blocked" , "Prohibited" , "Refused access to, say pub" , "Wouldn't allow" , "Precluded, obstructed" .)
