This article contains a list of reconstructed words of the ancient Dacian language. They have been restored by some linguists from attested Dacian place and personal names (toponyms and anthroponyms) and from words believed to be Dacian relics in the modern Romanian and Albanian languages. In the case of words reconstructed from onomastic evidence, the original meanings ascribed to the names in question are derived from examination of closely cognate words and placenames in other Indo-European languages, complemented by analysis of the historical evolution of such placenames. However, the results are hypothetical and subject, in many cases, to divergent etymological interpretations. Reconstructions derived from Romanian and Albanian words are based on the unproven theory (with some linguists and historians, this theory has become an assumption) that Dacian constitutes the main linguistic substratum of both languages, or the related theory that Dacian and early Albanian both descend from an immediate common ancestor.
