The false term is both a noun and an adjective. What is wrong is neither true nor authentic. As such, we will bring about the terms associated with it: the falsity and falsification. False means the lack of truth or authenticity. A falsehood may be a lie, which is a statement which occult or procrastinating the reality of a partial or total way. For example: a child breaks a vase without that anyone not noticing; When his mother asked him if anyone knows who broke it, he replied that not. In this case, the child told a falsehood because he lied.
In the sense of authenticity, the false (or falsity) is typically coupled with an imitation claiming to pass by the original object. Some typical examples are false money and clothes which copy major brands: "the fake of the ticket is verified by ultraviolet rays," "I realized it was the false Cook by reading the label of the jacket.
Furthermore, the falsity is associated with hypocrisy, which occurs when a person is pretending to have qualities or feelings contrary to those that she's for real. Falsehood concerning non-conformity between ideas and the words or actions: "the falsity of Ferdinand is not believable: he told me that he wanted me more than anything in the world while I saw him embrace Magali the other day.
Under the law, the false (in the sense of falsification) is an offence which consists in the alteration or simulation of truth having significant effects. That said, falsifying money tickets or marks (seals, stamps, signatures, etc.) is an offence punishable by law.
Finally, for philosophy, falsity is the opposite of the truth (the false is the opposite of the real) without this situation implies something objective or subject to the contingency.
