Notice venue (4)
I believe the answer is:
spot
This might be a double definition.
'notice' is the first definition.
(spot can mean to notice or observe)
'venue' is the second definition.
The answer and definition can be both locations as well as being singular nouns.
Perhaps there's a link between them I don't understand?
Can you help me to learn more?
(Other definitions for spot that I've seen before include "jam > stain" , "Notice; skin blemish" , "See; round mark" , "precise location" , "Discern - mark" .)
