Notice place (4)
I believe the answer is:
spot
I believe this is a double definition.
'notice' is the first definition.
(spot can mean to notice or observe)
'place' is the second definition.
(synonyms)
(Other definitions for spot that I've seen before include "Notice; sign of acne" , "point on snooker table" , "Blob" , "moral flaw" , "Sight - site" .)
