The base word in "invalid" is "valid," which means something that is acceptable or true. When you add the prefix "in-" to "valid," it changes the meaning to "not valid" or "not acceptable."
The term validity is the action of validating something. When something is valid, it is real, legitimate, or a true true statement about a topic or subject.
"Legitimate" can function as both an adjective and a noun. As an adjective, it describes something that is lawful, authentic, or valid. As a noun, it refers to a person who is born of married parents or to something that is accepted as true or valid.
To prove something from the impossibility of the contrary means to demonstrate that a statement or proposition must be true by showing that its negation leads to a logical contradiction or an absurdity. This method, often referred to as proof by contradiction, relies on the principle that if the opposite of a claim cannot be true, then the original claim must be valid. Essentially, it reinforces the original assertion by eliminating the possibility of any alternative scenario.
Valid means that something is logically sound or based on acceptable reasoning, while accurate means that something is correct or true to a certain degree of precision. Validity relates to the strength of an argument or statement, while accuracy relates to how close a measurement or statement is to the truth.
It means that something which was valid (or true) before a change remains true after a change. For example, the area of a shape is preserved under translation or rotation.
Facts cannot be valid. They can only be true or false. Arguments, on the other hand, can be valid. A valid argument in one which must have a true conclusion provided that the premises are true (no guarantee of that though).
