Abstract This paper discusses the gender changes that can take place in neuter nouns in Slovene dialects on the basis of number (singular, plural and dual). Using linguistic geography methods and material collected for the ongoing ‘Slovene Linguistic Atlas’ (SLA), the forms of a selected neuter noun are presented on three linguistic maps, which show the geographical spread of the gender changes. The paper also draws a comparison with earlier syntheses of these phenomena in Slovene.
