Role in Henry V sounds like something anyone could play (3)
I believe the answer is:
nym
If this is the answer, I'm afraid I cannot explain it.
Can you help me to learn more?
(Other definitions for nym that I've seen before include "Follower of Falstaff" , "Pistol's companion (Henry V, MWOW)" , "Falstaff crony (Hen.V)" , "A servant of Falstaff" , "Criminal crony of Falstaff" .)
