Told jokes with one's mouth covered? (6)
I believe the answer is:
gagged
'told' is the definition.
The answer and definition can be both to do with communicating as well as being past participle verbs.
Perhaps there's an association between them I don't understand?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for gagged that I've seen before include "Silenced" , "Muffled or retched" , "Not allowed to speak out" , "Struggled for breath or prevented from speaking out" .)
