are aramaic and greek only ancient languages or are they both modern and ancient?

Classical Greek evolved over the years so that Modern Greek is now very different.

Aramaic is basically an ancient language - from around the area of Syria - although there are still some speakers scattered around the region today.

Greek obviously is a modern language, but so is Aramaic. There are still a few speakers left in the middle east, although obviously it's not exactly the same language that was spoken at the time of the New Testament.

I cannot speak for Aramaic, but Greek is both modern and ancient.

As an example of how words have changed:

[tim-eh] τιμαι = honour (ancient)

[tim-ee] τιμή = honour (modern).

Furthermore, modern Greek has introduced lower-case letters and spaces between words and has been influence by French and Turkish, mostly. With small influences from other languages, including English.

As far as I know,Greek has 2 variants -- modern & ancient.

Aramaic is a dead language.Nobody speaks it now.

But I'm not sure about the second one,maybe I'm wrong.

Hope it helps you a bit.
