It focuses on lexical formation processes such as abbreviations, truncations, neologisms, and borrowings, and their function in digital communication. The descriptive and analytical approach, based on a corpus of comments, reveals a dynamic, coded, and spontaneous language, representative of a connected youth. These practices illustrate a conscious adaptation to the constraints of speed, while conveying a strong sense of identity. In the Algerian context marked by multilingualism and intercultural exchanges, these uses could reflect the emergence of a linguistic variety specific to young Internet users.frlexical creativityAlgerian studentsFacebookabbreviationsneologismsdigital communicationmultilingualismcoded languagelinguistic identitylinguistic variety.Thesis
