Sandwich filling for actor (3)
I believe the answer is:
ham
This could be a double definition.
'sandwich filling' is the first definition.
'ham' can be an answer for 'sandwich' (thesaurus). I am not certain of the 'filling' bit.
'actor' is the second definition.
(I know that ham is a type of actor)
'for' acts as a link.
Can you help me to learn more?
(Other definitions for ham that I've seen before include "Licensed amateur radio operator" , "Tasty meat for thespian who overacts" , "This actor overacts" , "Meat for actor who overdoes it" , "Meat served in sandwiches" .)
