Resumen de El aporte de la sociolingüística histórica al estudio del español
This paper deals with theoretical and practical aspects of historical sociolinguistics. After a brief consideration of its goals, methodology, and the sources required for the construction of pertinent corpora, two important aspects of the evolution of Spanish in the Buenos Aires region are considered: the standardization of Spanish from the sixteenth Century up to the twentieth Century, and the evolution of address forms. Concerning thefirst topic, the author shows the decline of a group of phonic features normally considered äs "vulgäres y rusticos" (Lapesa 1980) and associated with the progress of standardization observed by means of the methodological tools of flexible stability and intellectualization. Concerning the second, a wide restructuring of address forms initiated about 1850 and continuing up to this Century is presented.
