Trask's Historical Linguistics / 4th edition

An approachable and engaging introduction to Historical Linguistics with up-to-date pedagogy including exercises, further reading and online support material.

Historical Linguistics is a core part of most linguistics programmes. With the more experienced linguistics student in mind, this book covers many subjects in considerable depth while not sacrificing an appreciation of the whole.

Includes examples and datasets from a wide variety of languages and language families, whereas most historical linguistics textbooks tend to just focus on the language family the author works on.
