Ebook: Lexikon proto‑borealicum et alia lexica etymologica minora

The first part is represented by a tentative lexicon of the Indo-European, Uralic and Altaic common heritage, based on the list of Nikolaj Dmitrievič Andreev, with other comments and additions.
The other smaller dictionaries refer to the basic 100 Slavic roots, the proofs of a velar spirant or laryngeal in Proto-Romanian as a substratum (Thracian) heritage and a glossary of some basic Lithuanian mythological terms (in Romanian)
