Phrygian is considered by some linguists to have been closely related to Greek. The similarity of some Phrygian words to Greek ones was observed by Plato in his Cratylus (410a). However, Eric P. Hamp suggests that Phrygian was related to Italo-Celtic in a hypothetical "Northwest Indo-European" group.
Dacian / ˈ d eɪ ʃ ə n / is an extinct language, generally believed to be Indo-European, that was spoken in the Carpathian region in antiquity. In the 1st century, it was probably the predominant language of the ancient regions of Dacia and Moesia and possibly of some surrounding regions.
