  The Dacians are generally considered to have been Thracian speakers, representing a cultural continuity from earlier Iron Age communities. Some historians and linguists consider Dacian language to be a dialect of or the same language as Thracian. The vocalism and consonantism differentiate the Dacian and Thracian languages. Others consider that Dacian and Illyrian form regional varieties (dialects) of a common language. (Thracians inhabited modern southern Bulgaria and northern Greece. Illyrians lived in modern Albania, Serbia, Montenegro, Bosnia-Herzegovina and Croatia.)
  
  The ancient languages of these people became extinct, and their cultural influence highly reduced, after the repeated invasions of the Balkans by Celts, Huns, Goths, and Sarmatians, accompanied by persistent hellenization, romanisation and later slavicisation. Therefore, in the study of the toponomy of Dacia, one must take account of the fact that some place-names were taken by the Slavs from as yet unromanised Dacians. A number of Dacian words are preserved in ancient sources, amounting to about 1150 anthroponyms and 900 toponyms, and in Discorides some of the rich plant lore of the Dacians is preserved along with the names of 42 medicinal plants.
