This is a small description of the evolution of the Basque language in Lumbier-Irunberri (Navarre). It has two parts: the first one it is a diachronic explanation of the evidences about the presence of the language, and its disappearing. In the second part we have explained how the Basque language has been recuperated and it is being normalized, instead of the obstacles. Finally, we have drawn some conclusions before suggesting some worklines. We would prove that this village has never lost absolutely the contact with the laguage, although it has not been spoken for aproximately two centuries.
