The worst actor in Hamlet (3)
I believe the answer is:
ham
This could be a double definition.
'the worst actor' is the first definition.
'ham' can be an answer for 'actor' (ham is a kind of actor). I'm not certain of the 'the worst' bit.
'hamlet' is the second definition.
(thesaurus)
'in' acts as a link.
Can you help me to learn more?
(Other definitions for ham that I've seen before include "Meat served in sandwiches" , "Tasty meat for thespian who overacts" , "Meat for the radio amateur" , "Overacting actor" , "Food" .)
