Point of issue (4)
I believe the answer is:
exit
This might be a double definition.
'point of' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'issue' is the second definition.
(I know that issue can be written as exit)
Can you help me to learn more?
(Other definitions for exit that I've seen before include "Way to go!" , "Sudden rush of pleasure" , "Move out" , "Way out sign" , "Relinquish the lead" .)
