`  ::I thought it was blatant to everybody that we've been using exonyms to describe the stages of the Greek language (and any language for that matter). If we had wanted to call the articles by the original language names, then we wouldn't have much of a choice: *Ancient and Koine Greek: Ελληνική  *Byzantine and Modern Greek: Ρωμαϊκή And obviously that would be inaccurrate. As Andreas said, 'Ελληνικός' is completely wrong because it's in masculin adjective form, and the noun that it refers to is of feminin gender (γλώσσα=language). ``Ελληνική γλώττα`` (Greek language) is also inaccurrate because it's a very general term written in Attic. Plain ``Ελληνική`` is already in use by the Greek language article, and it can also be confused with Koine Greek. Hellēnōn glōssan, is simply the noun Hellēn put into plural genitive, followed by Ionic glossa in singular accusative, signifying ``Greeks' language``. Hellada glossan (Greece language) means nothing on its own, it probably ties up with a dative in the rest of the sentence. I think the best thing would be the use of a capitalized 'ΕΛΛΗΝΙΚΗ' or the post-classic Greek term ``Αρχαία Ελληνική`` (Ancient Greek), or better yet nothing.  `
