Fellow actor? (8)
I believe the answer is:
playmate
This clue could be a double definition.
'fellow' is the first definition.
(I know that Playmate is a type of fellow)
'actor?' is the second definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's an association between them I don't understand?
Can you help me to learn more?
(Other definitions for playmate that I've seen before include "Child's friend" , "Childhood companion" , "Companion for fun" , "Recreational friend" , "Game participant" .)
