Synchronic sociolinguistics has been particularly convincing in its use
of quantitative models to demonstrates how 'the present might explain
the past'. However, the relevance of sociolinguistics to historical
linguistics 'using the past to explain the present', has been largely
ignored. In this volume Dr Romaine lays the foundation for a field of
research encompassing both historical linguistics and sociolinguistics,
which aims to investigate and account for language variation within a
particular speech community over time. The socio-historical approach is
illustrated here by a detailed analysis of the development of relative
clause formation strategies in Middle Scots. This case study raises
fundamental questions about the epistemological status of
sociolinguistic theory and in particular its claims to an empirical
foundation. Her own preliminary suggestions for a truly integrative
sociolinguistic theory will be of interest to sociolinguists, historical
linguists and general linguists.
