Any way that’s negative (3)
I believe the answer is:
nay
This might be a double definition.
'any way' is the first definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'negative' is the second definition.
(nay is a kind of negative)
'that's' is the link.
Can you help me to learn more?
(Other definitions for nay that I've seen before include "Negative answer" , "disagreement" , "telling a nicker from a pony?" , "Negative response" , "Archaic negative" .)
