I thought it was blatant to everybody that weve 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 wouldnt have much of a choice Ancient and Koine Greek   Byzantine and Modern Greek  And obviously that would be inaccurrate As Andreas said  is completely wrong because its in masculin adjective form and the noun that it refers to is of feminin gender language   Greek language is also inaccurrate because its a very general term written in Attic Plain  is already in use by the Greek language article and it can also be confused with Koine Greek Hellnn glssan is simply the noun Helln 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  or the postclassic Greek term   Ancient Greek or better yet nothing
