Atticism

Atticism (meaning "favouring Attica", the region that includes Athens in Greece) was a rhetorical movement that began in the first quarter of the 1st century BC; it may also refer to the wordings and phrasings typical of this movement, in contrast with various contemporary forms of Koine Greek (both literary and vulgar), which continued to evolve in directions guided by the common usages of Hellenistic Greek.
