What are place names? From where do they originate? How are they structured? What do they signify? How important are they in our life? This groundbreaking book explores these compelling questions and more by providing a thorough introduction to the assumptions, theories, terminology, and methods in toponymy and toponomastics – the studies of place names, or toponyms. It is the first comprehensive resource on the topic in a single volume, and explores the history and development of toponyms, focusing on the conceptual and methodological issues pertinent to the study of place names around the world. It presents a wide range of examples and case studies illustrating the structure, function, and importance of toponyms from ancient times to the present day. Wide ranging yet accessible, it is an indispensable source of knowledge for students and scholars in linguistics, toponymy and toponomastics, onomastics, etymology, and historical linguistics.
