False means untrue. If something is false, it means it is not real. A falsehood is anything said that is not true. A falsehood can also be a series of lies, told to "prove" something that is false itself.
In logic, "false" is one of the truth values (with the other one being 'true'). This is written as [math]\bot[/math], F or 0.
