Principles of Linguistic Change, Volume 1

This book develops the general principles of linguistic change that form the foundations of historical linguistics, dialectology and sociolinguistics. 

• Demonstrates the social as well as cognitive relevance of linguistic research
• Shows that rapid linguistic change is in progress in the cities of America and England so that urban dialects are becoming more and more differentiated
• Discusses factors that govern the internal development of linguistic structures: the mechanisms of change, the constraints on change, and the ways in which change is embedded in the larger linguistic system
