The author analyzes Ľudovít V. Rizner´s Dialektický slovník bošácky, points to the circumstances behind its origin and its use in Slovak dialectology. The goal of this paper is to show Rizner´s writings, to this day unused, concerning extralinguistical information and broader contextual characteristics of explained phenomena. These unpublished lexicographical texts offer wide possibilities for broad ethno-liguistical research.
