Abstract The notion of linguistic justice should be related to the concept of linguistic ease, by which we mean the full social and communicative freedom of concern of the speaker in a given social interaction involving the use of language(s) present in the society, according to the social norms of use. To acquire an acceptable degree of linguistic ease, the knowledge of at least one L2 is considered important. But the acquisition of a L2 is interfered by the previous linguistic skills of the learner/speaker who, in many cases, does not have a suitable competence even of the languages of the society in which he/she lives.
