Book excerpt: The Handbook of African Linguistics provides a holistic coverage of the key themes, subfields, approaches and practical application to the vast areas subsumable under African linguistics that will serve researchers working across the wide continuum in the field. Established and emerging scholars of African languages who are active and current in their fields are brought together, each making use of data from a linguistic group in Africa to explicate a chosen theme within their area of expertise, and illustrate the practice of the discipline in the continent.
