ENSztabinki Lake is situated in the middle of the Sejny Lake District (Northeastern Poland), in the old territory of the Yatvingian tribes. Yatv. *Stabing(i)s is a topographic name formed from Yatv. appellativum *stabis, OP stabis 'stone' E 32, to which a hydronymic suffix -ing- was attached. Originally, the formation was used in the adjectival attributive sense of 'stony, full of stones'. The etymology is well-grounded in the semantics of formation conformable to landscape features, if one takes into consideration the occurrences of the form in place names in the former Old Prussian region, as well as in a form of the Lithuanian name of the lake as Stabingis. Written forms derived from the name of the lake are recorded as early as the 16th century, e.g., in 1522 Stobinski (dwor), in 1560 Stabinska // Stebinska (ulica), and others. The examples illustrate past phonetic and morphological processes which resulted in the adaptation of the name to the Slavic morpho-phonetic environment (its transformation into a Polish form). The etymological analysis of the name has been supplemented with a comprehensive description of the microtoponymy of the Lake and its vicinity. The place names reflect the history of settlement and ethnic changes in the region. Evidence has been found that, in the course of last 500 years, at least five distinct ethnic groups (Yatvingians, Lithuanians, Byelorussians, Poles, and Great Russians - Old Believers) must have been involved in the history of the areas around the Lake.
