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."
We can all recognize fluency and practise to be fluent, but do not understand what linguistic and paralinguistic operations are involved. This book tries to solve this puzzle. It begins by exploring perceptions of fluency to understand their common denominators. It goes on to pinpoint the specific features which promote fluency while emphasising its relative and interactional nature. These analyses produce both a methodological framework and a pedagogical strategy, illustrated by sample classroom activities.
