(Its leading early proponent, Dionysius of Halicarnassus [c. 60–p. 7 B.C.E.], identified Lysias [c. 445–380 B.C.E.] as “the perfect model of the Attic dialect”, whose virtues he enumerates to be “purity of language, correct dialect, the presentation of ideas by means of standard, not figurative expressions; clarity, brevity, concision, terseness, vivid representation…, the pleasing arrangement of words after the manner of ordinary speech…, charm and a sense of timing which regulates everything else”.) • The stylistic principles of Greek Atticism in application to other languages, especially to Latin. • An expression or idiom characteristic of or peculiar to Attic Greek, especially an elegant and refined, if grammatically irregular, usage. • A refined felicity or well-turned phrase, especially one deemed ungrammatical.
