solecism

noun

Etymology: Borrowed from Middle French solecisme, soloëcisme (French solécisme) or its etymon Latin soloecismus, from Ancient Greek σολοικισμός (soloikismós), from σόλοικος (sóloikos, “speaking incorrectly”), from Σόλοι (Sóloi), an ancient Athenian colony in Cilicia whose inhabitants spoke a dialect regarded by Athenians as a corrupted and barbarous form of Attic Greek. Compare Atticism.

2. An error or improper usage.

   “The "simple" metaphor, such as the instance given, becomes the "continued" metaphor when the analogy or similitude is worked out in a series of phrases and expressions based on the primary metaphor; it is in such "continued metaphors" that the solecism of "mixed" metaphors is likely to occur.”

Clifton, Sept. 28th., "Best young woman!" repeated Mr. Lovel; "'pon honour, Jack, you have made a most unfortunate speech; however, if Lady Louisa can pardon you,-and her Ladyship is all goodness,-I am sure nobody else can; for you have committed an outrageous solecism in good manners."”

   “Under this plea, felons of the worst kind might claim, till this time, to be taken out of the hands of the law judges, and to be tried at the bishops’ tribunals; and at these tribunals, such a monstrous solecism had Catholicism become, the payment of money was ever welcomed as the ready expiation of crime.”
