How and why do languages change? Where does the evidence of language change come from? How do languages begin and end?

This book will show you why it is neither, and that understanding the factors surrounding how language change occurs is essential to understanding why it happens. This updated edition remains non-technical and accessible to readers with no previous knowledge of linguistics.

Human language is a weird communication system: it has more in common with birdsong than with the calls of other primates. Jean Aitchison explores the origins of human language and how it has evolved. She likens the search to a vast prehistoric jigsaw puzzle, in which numerous fragments of evidence must be assembled.

This is an accessible and wide-ranging introduction to the origins and evolution of human language.
