The relative clause marker in Scots English: Diffusion, complexity, and style as dimensions of syntactic change

A historical study of variation in the relative clause marker in Scottish English indicates that sociolinguistic methodology has some important contributions to make to historical linguistics. The use of the frequency with which NPs in certain syntactic positions are relativized as a measure of syntactic complexity reveals that the WH relativization strategy appears to have entered the language in the most complex styles and least frequently relativized syntactic positions, until it eventually spread or diffused throughout the system. The addition of the WH relativization strategy seems to have resulted in a 'squish' of two strategies which are opposed in stylistic meaning rather than in actual qualitative change in the relative system. The process of diffusion can be seen as completed as far as the more formal styles of the modern written language are concerned, but it has not really affected the spoken language, where the native TH strategy prevails.
