This work is written within two actively developing areas of linguistics: sociolinguistics and media linguistics (term by T.G. Dobroklonskaya) (Доброклонская, 2008). The article is devoted to the study of a complex linguistic and sociocultural phenomenon – the modern Spanish youth language. The youth language is considered in this work as one of the social dialects, which generally corresponds to the concepts and approaches of modern linguists. The "youth language" is interpreted by the authors of the article as a concept that includes not only linguistic phenomena, but also a number of sociological, ideological, semiotic aspects of youth communication (Yakubova et al., 2016). The work uses the concept of "youth language" (equated to the Spanish terms argot juvenil, jerga juvenil and lenguaje juvenil) to denote the linguistic aspects of communication, namely speech manifestations and language codes inherent in the youth environment. The article attempts to conduct a multifaceted study of the modern language of Spanish youth on the basis of the television series "El desorden que dejas" (2020).
