This book "asserts that the origin and spread of languages must be examined primarily through the time-tested techniques of linguistic analysis, rather than those of evolutionary biology" and "defends traditional practices in historical linguistics while remaining open to new techniques, including computational methods" and "will appeal to readers interested in world history and world geography."
This is the eleventh volume in Professor M.A.K. Halliday's Collected Works. First published as a ten volume set from 2002 to 2007, they have shown the sizeable and growing international interest across a number of disciplines in the systemic functional linguistics framework.
Halliday's powerful theoretical approach to the study of language has contributed significantly not only to advances in our knowledge of how language works but also how linguistic insights may be practically applied across a wide spectrum of social concerns.
