The presented here article analyses the features of a language occurring in the border. The results were achieved by using the ethno-linguistic method, which is based on the systematic analysis of the ritual structure and vocabulary. The object of the analysis was a little fragment of the spiritual culture – the winter period of the ritual year. The structure of the ritual was established according to the methodology as well as the terminology of rituals, which includes several lexical-semantic microfields, was analyzed. The research was carried out nearby Vilnius (region of Vilnius, partly Širvintai and Molėtai) and also in the regions close to Byelorussia (Šalčininkai and Švenčionys).
