Fair entertainment? (3)
I believe the answer is:
fun
This clue could be a double definition.
'fair' is the first definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe there's an association between them I don't understand?
'entertainment?' is the second definition.
(fun is something entertaining)
Can you help me to learn more?
(Other definitions for fun that I've seen before include "Enjoyment" , "'Merriment, playfulness (3)'" , "Jollification" , "Entertaining" , "Light-hearted pleasure" .)
