Key location to get a drink that's out of this world (5,3)
I believe the answer is:
This might be a double definition.
'key' is the first definition.
(I know that space bar is a type of key)
'location to get a drink that's out of this world' is the second definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
Can you help me to learn more?
(Other definitions for space bar that I've seen before include "Long key on a typewriter" , "Key feature" , "key, large one" , "Restaurant at the End of the Universe?" , "Keyboard key" .)
