Thracian

Thracian ( THRAY-shən) is an extinct and poorly attested language, spoken in ancient times in Southeast Europe by the Thracians. The linguistic affinities of the Thracian language are poorly understood, but it is generally agreed that it was an Indo-European language.

The modern understanding of Thracian is built on a massive corpus of personal names (onomastics), place names, and a few deeply obscure inscriptions that have defied clear interpretation.
