The Linear B used about 88 syllable signs and determinative logogramms. As it was inherited by Greeks from Linear A, another Cretan script of unknown origin, it did not reflect fully the Hellenic phonetics. For example, no distinction between long and short vowels existed in writing, but we know they were different in Greek even much later. Double consonants also could not be reflected. The script shows practically no r, l. At the end of the syllable we can't see any l, m, n, r, s, and this hardens research a lot. But anyway, the language remains Greek, with its complicated declension and conjugation system, Indo-European numerals like du-wo (two), ti-ri (three), e-ne-wo (nine), etc. And much progress was done in Linear B comparing to Linear A: for instance, Linear A does not distinguish the difference between [p] and [b], but such a distinction existed in Mycenaean Greek.
