The paper presents the results of research on microtoponymy expressed by litoralonyms and
pelaghialonyms of two neighboring lakes in the Dobrzyńskie Lake District (Eastern extremity of
Dobrzyń nad Wisłą Land): Lakes Szczutowskie and Urszulewskie. Litoralonyms (L) are defined
as names of inhabited or uninhabited points and area of the waterfront; pelaghialonyms (P) instead
are names of lake fishing depths or areas on the surface of the water, recognized and used by local
communities. The names of the L- and P-type meet in many cases, features interchangeable or joint
in their function. They are motivated by topography, forms of the surrounding landscape and the
natural
state of the lake, but especially by a large extent of the human factor, i.e. anthroponyms
associated
with building plots along the shoreline, and the names of the components of rural infrastructure.
