Like its Slavic counterpart (2008), the Etymological Dictionary of the Baltic Inherited Lexicon aims at combining recent insights from comparative Indo-European linguistics with modern Balto-Slavic accentology. While the Lithuanian lexicon serves as a starting-point, the dictionary contains a number of etyma that are unique to Latvian or Old Prussian. Unlike in most other Baltic etymological studies, both Latvian and Lithuanian accentual data feature prominently. The author's renewed attempt to reconstruct part of the Balto-Slavic lexicon has resulted in numerous additions and corrections.

The introductory chapter explains the structure of the dictionary and clarifies its theoretical framework. In addition, it provides a concise introduction to Baltic historical linguistics. The volume concludes with an extensive bibliography and a word index.
