For the unfamiliar, Linear A was an ancient script that is associated with the Minoan civilization of the island of Crete, around 1500 - 1800 BC. The later Linear B system encodes archaic Greek, and is very similar to Linear A in glyph form. The Minoan language written with Linear A is probably unrelated to any other language.<p>Phonetic values are necessarily from Linear B or otherwise guesses - it's very likely there was a great deal of overlap, that the symbol representing, for example, the syllable "ni" in Greek, represented a syllable that sounded a lot like "ni" in Minoan. (Linear B is quite unsuited to writing Greek sounds, an indicator that it was borrowed from a very different language.) But since the language of Linear A remains undeciphered, that is really just an educated guess at best.
