The objective of the present work is to show the most significant actions and results of the Cuban linguistic policy, which is directed towards increasing the standards of the culture and the linguistic knowledge of all the citizens by legitimating the high norms of the Cuban variant of the Spanish in its lexical, phonic and grammatical levels. It also aims to keep its union with the Spanish world respecting and acknowledging the diversity. Furthermore, it states the acknowledgement and respect to other languages which coexist with Spanish in the Cuban territory, through the assumption of linguistic strategies which favor everyone.
