Meaning

  1. Late LatinfemininesingularAttic Greek (prestige dialect of Ancient Greek)
    Quinque sunt linguae Graecorum, Ias Doris Atthis Aeolis coene.late 4th century CE, Diomedes Grammaticus, Artis Grammaticae libri III 440.5
    Atthis, quae brevitati studet, admittit soloecismos, quos cum docti fecerint, non soloecismi sed schemata logu appellantur, ut est n u d a g e n u et u r b e m q u a m s t a t u o v e s t r a e s t.Attic, which favours concision, allows solecisms [which], when learned men have committed them, are called not solecisms but figures of speech, as for instance “nuda genu” [Vergilius, Aeneis 1.320] and “urbem quam statuo vestra est” [opere citato 1.573]. For in those places [Virgil] ought to have said “nudum genu habens” and “urbs quam statuo vestra est”. But in service to the [rhetorical] figure, that which is called Hellenism has reduced the three parts of speech to the two of usage on account of Atticism.late 4th century CE, Diomedes Grammaticus, Artis Grammaticae libri III 440.16–23
