Are Welsh Place Names Disappearing? What the Evidence Shows
On this page
The best available national study found no evidence that Welsh place names are disappearing nationwide. In the formal street and property naming applications it examined, Welsh names were more common than English ones, and changes from English to Welsh were several times more frequent than changes in the opposite direction.
That does not mean every historic name is secure. Formal records miss informal renaming, online tourism labels and many landscape features. The evidence supports a more interesting conclusion: Welsh names remain resilient, while particular names and places can still be vulnerable.
Why Welsh place names matter
A place name can be a miniature archive. It may describe a river bend, a church, a farm, a woodland, an old owner or the shape of the land. The Geiriadur Prifysgol Cymru shows that aber often refers to a river mouth or confluence, llan commonly signals an early religious enclosure or church settlement, and cwm means a valley.
Those elements are useful clues, not mechanical translations. Names change through speech, spelling and centuries of local use. A convincing interpretation needs early written forms, local pronunciation and knowledge of the landscape. Similar-looking words can have different histories.
The Welsh phrase for place names is enwau lleoedd. They matter because they carry both language and memory. When a historic name is replaced, the loss is not merely decorative. A route into the story of that place may become harder to see.
Names also have a present-day function. They appear on road signs, maps, property listings, websites and spoken directions. That visibility helps make Welsh an ordinary public language. The issue is therefore both historical and practical: which names survive, which forms are standardised and which version people encounter first?

Are Welsh place names disappearing nationwide?
The Welsh Government's nationwide geographical-names study examined formal applications for street and property names between 2018 and 2023. It also surveyed 7,361 properties in seven locations, including Abersoch, Llanberis and Llanidloes.
The formal application data ran against the idea of a simple national replacement of Welsh. There were 338 applications for Welsh street names and 95 for English street names. For property names, there were 1,444 Welsh applications and 1,125 English applications.
Most recorded renaming kept the same language. Where a language change did occur, a change from English to Welsh was three to four times more likely than a change from Welsh to English. That is meaningful evidence, but only within the systems examined.
| Finding | What it supports | What it cannot prove |
|---|---|---|
| Welsh street-name applications outnumbered English ones by 338 to 95 | Welsh was strong in the formal application records studied | That every street name in use is formally registered |
| Welsh property-name applications outnumbered English ones by 1,444 to 1,125 | There was no recorded nationwide rush towards English property names | How names are marketed informally or displayed online |
| Most renaming did not change language | Language replacement was not the norm in the records | That a historically significant individual name was unaffected |
| English-to-Welsh changes were three to four times more common than Welsh-to-English changes | The direction of formal language change favoured Welsh | That every local trend follows the national pattern |
The property survey added useful context. More than 60% of named properties in Abersoch, Llanberis and Llanidloes were Welsh. Yet the sampled names on Booking.com were 63.2% English, compared with 50.4% English in the wider landscape sample. This does not establish a national tourism effect, but it shows why online experience can look more English than the streets and properties around it.
The type of name changes the question
A settlement name, a street name, a house name, a mountain name and a business name do not pass through the same process. Some are official addresses, some are standardised geographical forms and some are informal labels with no application at all. A count drawn from one category should not be presented as the trend for every category.
The distinction also helps when a name has two forms. A bilingual sign may reflect an established Welsh and English pair, while a Welsh-only standard form may be recommended where the evidence supports it. Recording a historical variant is different again: preservation keeps evidence available even when another form is used for modern consistency.
A name should not be translated merely because its elements look familiar. Some English forms have long histories of their own, and some apparent translations are later inventions. The responsible choice is to show the evidence and avoid treating one rule as suitable for every place.
Why concern can still be justified
People do not experience naming change as a spreadsheet. One conspicuous replacement of an old farm or house name can carry more emotional weight than many routine applications. If the lost name describes a local feature or preserves a family history, the significance may be real even when the national direction is reassuring.
There is also a visibility gap. A property may retain its formal Welsh address while being promoted under an English trading name. A path, crag or beach may acquire a popular online label without any official application. Search results and booking sites can repeat that label until it feels established. Formal datasets are poorly suited to capturing such change.
The national study explicitly identified gaps around informal, digital, topographical, tourism and outdoor-recreation names. The right conclusion is therefore not that concern has been disproved. It is that the broad formal trend and the risk to particular names are two different questions.
What formal records still cannot see
A council application can record a change to an address, but it may not capture the nickname used by a holiday business, a label added to a climbing route or a spelling copied across social media. It also says little about which version appears most prominently in a search result.
Future monitoring would be stronger if it connected formal applications with sampled tourism listings, digital maps and important landscape features. Repeating the same samples over time would show direction, while interviews could explain why owners, residents and businesses chose a name. Those sources should remain separate rather than being forced into one headline total.
Housing debates can intensify the issue because naming, ownership and community change may appear together. They should still be analysed separately. Our guide to second homes and Welsh-speaking communities examines the housing evidence without treating a changed name as proof of a property's use.
Who decides which name appears?
There is no single national nameplate controller. Local authorities handle street naming and numbering within their responsibilities. The Welsh Language Commissioner provides standardised Welsh forms for settlements and geographical features. Ordnance Survey is not a naming authority. It uses official and local evidence when maintaining names on its mapping.
These roles solve different problems. Standardisation asks which Welsh spelling should be recommended for consistent official use. Historical protection asks what earlier names tell us and whether they should be recorded or considered when decisions are made. A standard modern form is not necessarily a judgement that every historical variant was wrong.
Local pronunciation remains important. A name that looks puzzling on paper may make sense when spoken by people who know the area. Documentary evidence matters too, especially early maps, tithe records, estate papers and censuses. Strong naming work brings written history, landscape and living speech together.
How names are protected
Wales has a statutory list of historic place names maintained through the national historic-environment framework. It contains hundreds of thousands of names gathered from historic sources. The list is a research and decision-making resource, not a rule that freezes every property name forever.
The Historic Environment (Wales) Act 2023 provides the current consolidated legal framework for the historic environment. The Cymraeg 2050 action plan for 2026 to 2027 also includes work on protecting Welsh place names. The practical test will be whether information reaches the people making real naming and planning decisions.
Digital preservation matters as much as a database. A name is more likely to survive when it is searchable, correctly spelled, connected to a source and used by local institutions. Schools, community councils, historians, walkers and businesses can all reinforce that chain.
A practical preservation ladder
Protection is most effective when it happens before a dispute. First, record the exact historic forms and their sources. Second, capture local pronunciation with the speaker's permission. Third, connect the name to a mapped feature or property. Fourth, use the agreed form consistently on signs, websites and listings. Finally, explain its history in plain language so that residents and visitors understand why it belongs.
This approach does not require every spelling from every century to appear on one sign. It creates a traceable record and makes any standardisation decision easier to understand. Where evidence conflicts, the disagreement itself should be preserved rather than hidden behind a falsely certain translation.
How to read a place name with care
When you encounter an unfamiliar Welsh name, start by preserving it exactly. Check the spelling on an authoritative map, then listen for a local pronunciation. Break the name into possible elements only after that. Our guide to easy Welsh words can help with some sounds, while our explanation of cynefin explores the relationship between language, place and belonging. Place-name history often still requires specialist evidence.
A useful four-question check keeps claims grounded:
- What is the earliest recorded form? Modern spelling alone can conceal the origin.
- Does the meaning fit the landscape? A tempting translation should match the actual place.
- How do local people say it? Pronunciation may preserve information that spelling does not.
- Is the proposed origin certain? Some names have competing explanations, and uncertainty is worth stating.
If a business uses a historic Welsh name, accuracy is a form of respect. Keep the spelling consistent and explain the meaning where it is secure. A secure explanation gives visitors useful context without inventing a picturesque marketing translation.
So, are Welsh place names disappearing? Not as a general national finding in the formal evidence. Welsh naming remains strong in the formal records studied, and recorded language changes more often moved towards Welsh. The unfinished work lies in protecting significant individual names and understanding the parts of modern naming that official systems still cannot see.
