The River-Names of Europe — Story, Setting & Ideas

Roots and Resistance to Change

Ferguson argues that river names are among the most stable linguistic artifacts. He contrasts the fate of small streams—brooks, becks, burns—whose ancient names were easily replaced by new settlers, with major rivers like the Danube, which flowed past many communities and thus retained its original appellation. This observation is grounded in a practical logic: a river that came from unknown sources and went to unknown destinations was a shared resource, and changing its name would have caused confusion. The book's method is to identify a root, such as tarddu (Welsh for 'to burst forth'), and then list rivers that derive from it: the Tarth in Scotland, the Tardoire in France, the Tartaro in Italy, and even the ancient Tartessus (Guadalquiver) in Spain. Ferguson is careful to note that some names may mix meanings—for instance, the root till (Sanskrit 'to move') might also involve boundary-marking, as in the Till in Northumberland or the Dill in Nassau.

Patterns of Derivation and Geography

The book's structure is taxonomic: each root is followed by a list of rivers grouped by suffix. For example, from the root taosg (Gaelic 'to pour') come the Tees in England, the Töss in Switzerland, the Tosa in Piedmont, and the Theiss in Hungary. Ferguson adds that the Tees and Tosa are noted for their falls, suggesting the root may carry a sense of cataract. He also includes rivers from outside Europe—the Touse in India, the Teesta—with a cautious 'here?' indicating uncertainty. The lists are dense with historical forms: Sprazah (9th century) in Lower Austria, Alkmana (8th century) now the Altmühl, Delvunda (9th century) now the Delvenau. These dates, taken from Förstemann, anchor the names in medieval records, but Ferguson does not always explain the reasoning behind his groupings, leaving the reader to infer the linguistic connections.

The Limits of Evidence and Inference

Ferguson is candid about the provisional nature of his work. In the preface, he acknowledges that 'some of its opinions might be modified or altered by a more exact knowledge of the characteristics of the various rivers.' The excerpts show him grappling with multiple possible etymologies: the Welsh dylif and dylwch (deluge) might also connect to Anglo-Saxon delfan (to dig). He sometimes hedges with phrases like 'may probably' or 'we may perhaps connect.' The book is a compilation of possibilities rather than a set of certainties, and its value lies in the breadth of its comparisons—linking the Sprint in Westmoreland to the Sprotta in Silesia, or the Test in Hampshire to the Teesta in India. Readers should approach it as a pioneering work of philological geography, not a definitive dictionary.

Structure and Method

Ferguson organizes his material by linguistic roots, not by river systems or countries. Each chapter treats a root like al (to go) or gad (to gush), then lists rivers that derive from it, often with suffixes like -en, -er, or -es. He draws on multiple languages: Sanskrit, Gaelic, Welsh, Anglo-Saxon, Old High German. The result is a web of connections that spans from Scotland to Siberia. For instance, the root gad yields the Gotha in Sweden (noted for its fall at Trollhättan), the Gaddada in Hindostan, and the Giessbach in Switzerland. Ferguson also includes ancient names like Halycus (now Platani) and Alces in Bithynia, showing a wide temporal range.

Ferguson's work is best read as a reference and a provocation. The lists invite the reader to see patterns across languages and landscapes, but the author's own cautions remind us that many of these etymologies are speculative. For anyone interested in the deep history of European geography, this book offers a unique lens—one that treats river names as fossils of ancient speech, waiting to be deciphered.

I keep thinking about that old book on river-names, how a single word like al could quietly carry a whole people's path across centuries. It reminded me of something gentler, The Aboriginal Population of the North Coast of California — Story, Setting & Ideas, where names cling to places like moss on stone. Both left me feeling the land holds more memory than we ever voice out loud.
