2.1.1. Indo-European does not have an old writing system to be revived with. In the regions where PIE speakers dwelled four thousand years ago, caves and stones probably still keep some ancient pictographic writings, composed of logograms (graphemes) that represent a morpheme or a whole word, as did Egyptian hieroglyphic logographs.

2.1.2. The Indo-European dialects have adopted different alphabets during the last millennia, and all of them should be usable today – although the main alphabet for today’s European Union is clearly the Latin one. This is a summary table of Proto-Indo-European phonemes and their regular corresponding letters in MIE alphabets: Greek, Latin, Cyrillic, Perso-Arabic and (alphasyllabary) Devanāgarī.
