Artist's entrance (7)
I believe the answer is:
ingress
This might be a double definition.
'artist's' is the first definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'entrance' is the second definition.
(I know that entrance can be written as ingress)
Can you help me to learn more?
(Other definitions for ingress that I've seen before include "Way in" , "going in" , "The act of entering" , "Ribbon-like pasta" , "right of entry" .)
