Globe falls off strobe light? You'll have to go to the bar to sort out that problem! (6)
I believe the answer is:
thirst
This might be a double definition.
'globe falls off strobe light? you'll have to go to the bar to sort out that' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'problem' is the second definition.
The answer and definition can be both states of affairs as well as being singular nouns.
Maybe you can see a link between them that I don't see?
Can you help me to learn more?
(Other definitions for thirst that I've seen before include "The inducement for 5 Down" , "Hunger" , "A craving for drink or knowledge" , "Quaff to slake it" , "A need (for liquid)" .)
