Where Do Place Names Come From? Reading a Map as a Document

Toponyms cluster into a small number of types that recur across unrelated languages:

• •Physical description, naming a hill, ford, marsh, bend or confluence, which is the largest category and the most stable because the feature outlasts everything
• •Vegetation and animals, recording what grew or lived there, which supplies evidence about past ecology
• •Ownership, attaching a personal name to a settlement, which in England produces the enormous number of places combining a name with an ending meaning farm or homestead
• •Function, naming a market, a mill, a crossing, a toll point or a religious site
• •Relative position, giving the many names meaning north, upper, little and new, usually in relation to an older settlement nearby
• •Transferred names, carried by settlers and applied to a new place, which is why the map of North America and Australia is full of European names with New in front
• •Commemoration, honouring a person or event, which is the most recent type and the most frequently changed

British place names are unusually well studied and show the layering clearly. A few river names are pre-Celtic and cannot be explained from any known language, which makes them probably the oldest words still in use in the country. Celtic elements survive widely, particularly in the west and in river and hill names, including the element that becomes Avon, which simply means river, so Avon river is a tautology. Roman contributions are fewer than expected, with the element from castrum, meaning fort, surviving as chester, caster and cester. Anglo-Saxon endings dominate the east and midlands, including ton for farmstead, ham for homestead, ley for clearing, ford, bury and worth. Scandinavian settlement is visible in the north and east through by for village, thorpe for outlying settlement, thwaite for clearing and toft for plot, and the distribution of those endings maps the area of Danish control closely enough to be used as evidence for it. Norman French contributed relatively few names and many additions, which is why so many places have a double-barrelled name where the second part is a Norman lord's family.

Names accumulate mistakes and the mistakes stick. Tautological names arise when a later people adopt a name they no longer understand and add their own word for the same feature, producing hills whose names mean hill hill hill in three successive languages, of which Torpenhow in Cumbria is a much-cited example. Folk etymology reshapes an opaque name into something that sounds meaningful, so an unfamiliar element is reinterpreted as a familiar word and the spelling follows. Mistranscription by clerks unfamiliar with local speech has fixed spellings that never matched pronunciation, which is part of why British place names are pronounced so unpredictably. Colonial mapping recorded names filtered through an unfamiliar phonology, and in several documented cases recorded an indigenous phrase meaning something like I do not understand you as the name of a place or animal, though the best-known versions of that story have not survived checking.

Because a name asserts whose place it is, renaming is a standard instrument of power and a standard act of reclamation. Colonial administrations replaced indigenous names systematically, and decolonisation reversed many, which is why numerous African and Asian cities and countries carry different names now than on mid-century maps. Regimes rename cities after leaders and successors rename them back, with Saint Petersburg, Petrograd, Leningrad and Saint Petersburg again being the standard example. Dual naming has become a common compromise, restoring an indigenous name alongside or instead of an imposed one, as with Uluru, Denali and Aotearoa. Disputed names are a live diplomatic issue, and international bodies maintain standardisation programmes attempting to reduce ambiguity for navigation and emergency services while avoiding endorsement of contested claims. Even within a country, street naming committees make decisions that are understood as statements about who is commemorated, which is why they generate disproportionate argument.

Place names describe terrain, vegetation, ownership, function, position and transfer, with physical descriptions the oldest and most durable because the feature outlives its namers. British names layer pre-Celtic river names under Celtic, Roman, Anglo-Saxon, Scandinavian and Norman elements, and the distribution of Scandinavian endings maps Danish settlement. Tautological names, folk etymology and clerical mistranscription fossilise errors, and renaming remains a direct instrument of political claim.
