Hey you guys, why guess? There are perfectly good definitions in
Webster's, along with examples.

I think you have the Inverse and the Contrapositive reversed. I always
have to set myself straight by considering a more obvious conditional,
such as "If it is not a mammal, then it is not a cow."

"I scored the next great triumph for science myself,
to wit, how the milk gets into the cow. Both of us
had marveled over that mystery a long time. We had
followed the cows around for years - that is, in the
daytime - but had never caught them drinking fluid of
that color."
