Origin of falsityMiddle English falsete from Old French from Classical Latin falsitas
- The quality or condition of being false.
- Something false; a lie.
Instances may be quoted in abundance from old authors to show that the first three words are often strictly synonymous; but the modern tendency has been decidedly in favor of separating them, falsehood standing for the concrete thing, an intentional lie; falseness, for the quality of being guiltily false or treacherous: as, he is justly despised for his falseness to his oath; and falsity, for the quality of being false without blame: as, the falsity of reasoning. — the Century Dictionary, 1911.
Corresponding to false + -ity. From Middle French fausseté, from Late Latin falsitas.
