TY - JOUR N2 - This article is a contribution to the historical lexicology of the Proto‑Slavic language. It analyzes the etymologies of 110 Proto‑Slavic lexemes in the field of topography and hydrography and classifies them into chronological layers. It draws a distinction between lexemes inherited from the Proto‑Indo‑European language and the Balto‑Slavic community and the numerous lexemes that were innovated during different periods of the Proto‑Slavic history. Some of these lexemes, created on the basis of Indo‑European roots and lexemes, must have arisen in the early period of the Proto‑Slavic language, though many more lexemes have a Slavic motivation. They developed in a later period of the Proto‑Slavic history or possibly at the time when the Proto‑Slavic language began to split into dialects. Lexemes without certain etymology have been addressed in the article separately.
