This paper focuses on the English dialect in South Yorkshire, examining both traditional and more mainstream aspects over a period of thirty years. The hypothesis behind this study is that the degree or broadness of dialect decreases throughout the years, tending towards a more levelled, less regionally marked English. The corpus consists of scenes taken from three films directed by Ken Loach, they are: Kes (1969), Looks and Smiles (1981) and The Navigators (2001). It seems important to study traditional and to discover which changes can be observed over this period of time.
