I get confused when there's a double negative in a sentence. For example, "No duck doesn't like water."
Normally, I would diagram this:
/D --> W
Because I would negate the second term ("doesn't like water" becomes "does like water") and the sufficient condition would remain the same (no duck).
But when I think about it in English, I realize that the double negative cancels each other out so it's like saying, "All ducks like water" which would be diagrammed:
D --> W
Any suggestions on getting past this hiccup?
Thanks!
Thank you!
