I beat you, Leto... Nederlands (Dutch), Deutsch (German), Francais (french), I am also learning Espanol (Spanish). I have had 4 years of ancient Greek (Hellenika) in school, so, although I may sound like Shakespeare, people speaking modern Greek may be able to understand it...
Some sim ple (I have no idea how to use Greek symbols here, but phonetic:) hoi barbaroi ou gignoskousi tèn Hellenikèn
It means: The strangers do not understand Greek.
Dein Deutsch ist nicht slecht, Leto! Wie hast du das gelernt?
