The language of young people is constantly evolving, and its forms emerge within various linguistic communities, thus enriching the general colloquial language. Slangs are often created and used as a revolt against norms of the surrounding society. As Jean-Pierre Goudaillier highlights: “slang practices are in no way limited in time and space, since a language always had and always includes its own ways of avoiding the so-called academic form” (Goudaillier [1997] 2001: 10). In the language of young people, some lexical fields are richer in synonyms than others, e.g. drugs, women, alcohol, and money. The objective of our research is to identify lexical forms, expressions and elements of discourse used for the four chosen themes, relying on two different corpuses, the nineties series “Les lascars,” and an Internet podcast, “Norman fait des vidéos.” We will compare the use, frequency, and diversity of the forms in the corpuses.
