Impropriety \Im`pro*pri"e*ty\, n.; pl. {Improprieties}. [L.
   improprietas; cf. F. impropri['e]t['e]. See {Improper}.]
   1. The quality of being improper; unfitness or unsuitableness
      to character, time place, or circumstances; as,
      impropriety of behavior or manners.

   2. That which is improper; an unsuitable or improper act, or
      an inaccurate use of language.

            But every language has likewise its improprieties
            and absurdities.                      --Johnson.
