In this paper, I will make an approximation to the presence of words that come from the English language studying the Extremenian town of Mérida (Badajoz). To do this, from the implementation of the questionnaire for the study of the educated norm (Lope Blanch, 1972) and using as lexical base semantic fields of "the clothes", "the social life and entertainment" and the concepts of the theatre, the press, the film and the television (I have included also a subject area of internet), I will make a quantitative and qualitative analysis of a corpus composed of 25000 words. In the corpus, I include the use of foreign voices and also the presence of Spanish versions to describe some terms of English origin. With this research, I intend to observe the spread of anglicisms in the locality and I want to also check how semantic fields are foreign terms and why the presence of these voices in the current spanish.
