The notion of social networks alludes to a free exchange platform where Internet users exchange at ridiculous cost without geographical and ethnic barriers. For this fast mode of communication, text is the main means used to convey a message. The present study makes a descriptive and explanatory analysis of some enunciative sequences of the text and shows that it is particular text because of the combined use of the alphabetic and numerical systems. In this variety of writing, the creation of lexical units and syntagmatic sequences are multiple and respect no grammatical rule. Thus, we note the construction of syntagms by the use of the syllabogram, the logogram, the truncation by apocope and by apheresis without excluding the multiple omissions of vowel and consonant whose texting is enamelled. Moreover, the whimsical and playful dimension linked to the production of utterances whose form varies according to the creative genius of each writer makes it difficult to decode the messages conveyed. At a time when the use of NICT essential in the field of communication, the study suggests that linguists lead in-depth reflections to sit a text grammar whose rules will serve to put all users at the same level of competence in encoding and the decoding of utterances.
