The paper analyses Rusin phraseological units with a number as their component, which were continuously sampled from lexicographic collections (dictionaries), such as The Rusin-Ukrainian-Russian and Russian-Ukrainian-Rusin Dictionary by D. Pop, The Rusin-Russian Dictionary by I. Kercha, as well as Ukrainian and Russian proverb dictionaries. The sampled phraseological units are distributed into groups depending on the core component – the numeral – and set against the background of a number of examples from Slavic languages. The phraseological units analysed in the paper are for the most part based on the symbolic semantics of numbers, reflecting popular beliefs, Christian faith, and mythopoetic numerology. Rusin phraseological units with numeral odin (‘one’) prevail in terms of quantity, which reflects the general tendency of Slavic phraseology. Relatively numerous are the groups of phraseological units with numerals dva (‘two’) and tri (‘three’). Other numerals are represented in Rusin phraseology to a lesser extent. This paper shows that the Rusin language is an example of a cultural and language transfer, since it was influenced by various languages due to a wide geographical “spread” in Europe. The identification of the national specificity against the background of a universal component helps to objectively and thoroughly reveal the linguistic and cultural potential of both Rusin and closely related Ukrainian and Russian paremiologies.
