Interpreting place names
Possibly the most famous quote about Welsh place names is the response given by the early 20th century scholar Sir Ifor Williams when asked to interpret a particular name, “dim ond ffyliaid fyddai’n treio esbonio enwau lleoedd” – only fools would try to explain place names! Whilst that might be putting it a bit too strongly (speaking, as it were, as a professional fool…), Sir Ifor did have a point. To put it another way, you do have to be a bit careful when trying to identify precisely what a particular place name refers to, so in this blog I thought it would be useful to discuss some of the issues involved in the interpretation of Welsh language place names, and to point to some of the resources available to aid in the understanding of them.
The first thing to remember is that the vast majority of names are readily understandable for the fluent Welsh speaker. This however does not particularly help those people who don’t (currently!) speak Welsh. The two most asked questions about Welsh language place names are 1. What does it mean, and 2. How do you say it?
All place names are made up of elements, the individual building blocks that are put together to construct a particular name. These are words like tref, bryn, coed, mawr a bach. On our website we’ve compiled a glossary of the most common of these elements, with a translation into English, so that you can understand them. We’ve also given a few examples of these elements in use in various place names. This is particularly important because, as you may know, the first letters of Welsh words can change in a variety of ways, due to the grammatical rules of the language. This is referred to in English as initial consonant mutation, or treiglo in Welsh, and is characteristic of all the modern Celtic languages. It may sound complicated at first, but it’s actually fairly simple once you get used to it. We’ve also provided an audio file of each element being pronounced, in order to help you learn to say the names properly.
Of course, that still doesn’t help with those names who’s meanings might not be readily apparent. Most often this is down to the natural evolution and slurring of a name over the centuries. Brymbo in Flintshire is a great example of this. The name was originally Bryn y baw, but the two elements bryn and baw (dung,flith) have been pushed together in speech, and then baw has been de-voiced due to the emphasis in the word being placed on the first element. A similar process has occurred with Abermawddach, which slowly became Abermaw and then Y Bermo, anglicised to Barmouth. The only way, in these circumstances, to identify the correct meaning of the place name is to ensure that you have consulted the full range of historical attestations of the name, and particularly the earliest ones. Once you’ve done this you’ll be able to see how the name has developed over the centuries, and hopefully to discover it’s meaning.
Be careful! Some forms might suggest a particular etymology which is then contradicted by earlier forms. A good example of this is Lunnon on the Gower, which is recorded as Llwynon in Edward Lhuyd’s Parochialia in 1699. Unfortunately, earlier spellings, such as Lunan in 1322 do not support this interpretation.

It’s also very important to remember that most place names have fairly pedestrian meanings; they refer to landscape characteristics or things in it. Despite this, people are very fond of ascribing romantic or dramatic meanings to their local place names. Almost every place with coch in its name for instance, will be explained as having come about because there was a battle there, and the gwaed coch of the soldiers who died there stained the place red. The truth is unfortunately rather more prosaic; quite often it’s a reference to the colour and condition of the soil locally.
It's also worth mentioning that the thing the place name refers to may no longer exist. We know for example that Wales has been largely deforested over the centuries, but many names survive that attest to the presence of now disappeared woodland. If you come across a name with coed or prysg in it far away from any modern woodland for example, it is likely to refer to a wood that has been lost over the course of history. Some good examples of these are Cerrig yr Argoed on the uppers slopes of Dyffryn Ogwen, and Argoed Fawr, a farm above Talybont in Ceredigion. These two names give an indication of how far up the hillsides the trees used to reach.

All this explains why we’re constantly adding more and more names to our database, and why we display everything all at once on the map. The more information people have about the development of place names, the more easily they’ll be able to understand them.
