Curious about line judge in complete control (12)
I believe the answer is:
stranglehold
This clue could be a double definition.
'curious about line judge' is the first definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'complete control' is the second definition.
(having a stranglehold means having total control)
'in' acts as a link.
Can you help me to learn more?
(Other definitions for stranglehold that I've seen before include "tight grip!" , "Complete power over a situation" , "Total restriction" , "Inexorable grip" , "Complete control" .)
