Chapter 6. How are linguistic changes in the 20th century to be studied?

Abstract

This paper analyzes the diffusion of linguistic change through a case study focusing on the adoption of tío as a vocative and discourse marker in the 1970s and 1980s. Two strands of research are used to explain this case: Firstly, Labov’s (2010) theory of diffusion in linguistic change is used to provide essential insights about the groups of speakers who initiate and promote such changes. Second, philological information is considered, encompassing factors beyond groups of speakers: the linguistic features of the constructions involved in a change, the historical context in which the change occurred, the associated social practices, the influence of specific locations (cities, neighborhoods), and also the impact of influential individuals in promoting one linguistic solution over another. It is only when both sets of information are brought together that the necessary and sufficient information about linguistic change can be achieved. The 20th century proves particularly suitable for conducting this type of research.
