I thought the word “canny” should start with capital “C” because Canny is the inventor of the well-known “Canny edge detector”.
Today I found canny is an adjective and there is another word “uncanny”
Strangely, I have never heard both words as an adjective.
However, “uncanny” doesn’t seem to be the antonym of “canny”. Does it?
