In the first part of the paper the author provides an overview of researh regarding Ruthenian / Rusyn youth speech. The English language has caused several innovations in the speech of young Ruthenians / Rusyns of Serbia. They can be seen at all levels. It is a well-known fact that modern languages today borrow extensively from English and consequently their lexicons are swarming with anglicisms in all thematic registers (especially in the register of computing, for ex. рестартовац компютер, конектовац ше на веб, зиповац файл). A morphological analysis of the English element in the MAK provides us with a basis for emphasizing a certain quantitive and stimulative influence of English on the occurence of indeclinability of nouns in the adjectival function in compounds consisting of two independently used bases. This is, however, a productive characteristic which might cause a change in the morphological and syntactic system of the Ruthenian language (for ex. Kulpin Fest, Vojvodina Calling, Headroom студиo).
