Modern Lithuanian has two grammatical numbers: singular and plural, nevertheless literature sources note the existence of the dual number residue in Lithuanian. This phenomenon is prominent in Austronesian languages as stated by Schwartz (1989:237-238) and there are different types of duals. However, in European languages this phenomenon is not as widely spread. This paper overviews the constructions of such phenomenon and presents results of a small research which looked at the frequency of the usage of dual pronouns and demonstratives in the Lithuanian language. Data for the research was taken from the Corpus of Lithuanian Language compiled by Vytautas Magnus University, Kaunas, Lithuania which is accessible online. The main aim is to discuss the place of duals in Lithuanian language and to establish whether it is still frequently used by the Lithuanian language speakers.
