negation
by switching the truth values of the hypothesis and conclusion, it is called the contrapositive of the original statement. The contrapositive of a true conditional statement will also be true, while the contrapositive of a false conditional statement will also be false.
Truth conditional semantics is a theory in linguistics that focuses on the relationship between the meaning of a sentence and its truth value. Examples of truth conditional semantics include analyzing how the truth of a sentence is determined by the truth values of its individual parts, such as words and phrases, and how logical operators like "and," "or," and "not" affect the overall truth value of a sentence.
Truth value
The statement "if not p, then not q" always has the same truth value as the conditional "if p, then q." They are logically equivalent.

According to truth-conditional theories of meaning, the meaning of a sentence is determined by its truth conditions, or the circumstances under which the sentence would be true or false. In other words, the meaning of a sentence is tied to its truth value in different scenarios, and understanding the meaning of a sentence involves understanding what would make it true or false.
