Chills debate outright (4)
I believe the answer is:
ague
This might be a double definition.
'chills' is the first definition.
(I've seen this in another clue)
'debate outright' is the second definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for ague that I've seen before include "Burning fever" , "Fever with shivers" , "met with cheek in Twelfth Night" , "Sweating, shivering, fit (once)" , "Hot and cold fever" .)
