This article presents the results of a research project whose aims were the following: to determine the frequency of the use of pronoun forms in polite treatment sumerce, usted and tu, according to differences in gender, age and level of education, among speakers in Tunja; to describe the sociodiscursive variations and to explain the relationship between usage and courtesy. The methodology of the Project for the Sociolinguistic Study of Spanish in Spain and in Latin America (PRESEEA) was used, and a sample of 54 speakers was taken. The results indicate that the most frequently used pronoun in Tunja to express friendliness and affection is sumerce, followed by usted and tu; women and men of different generations and levels of education alternate the use of these three forms in the context of narrative, descriptive, argumentative and explanatory speech.
