what is counterexample

A counterexample satisfies the hypothesis but denies the conclusion.

If today is the day that starts with the letter T,     then yesterday must have been Monday.

Today is Thursday (starts with a T),  then yesterday must have been Monday. That is false.

So, Thursday is the counterexample. @andy123123
