Vital facts to understand about the Welsh language

Are Welsh and Gaelic the same language?

No, Welsh and Gaelic are not the same language. Even to say Gaelic is one “language” isn’t quite correct. The Gaelic or Goidelic languages are actually a dialect continuum of three modern languages – Irish, Scottish Gaelic, and Manx.

All three modern Gaelic languages and Welsh are classed as living Celtic languages. However, Welsh is from a different branch of the Celtic language tree, what are known as Brythonic (British Celtic) languages. This means it has more in common with Breton or Cornish than Irish, Manx, or Scottish Gaelic.

A speaker of Welsh or any of the Brythonic languages will almost always be completely unintelligible to a speaker of any of the three modern Gaelic languages, and vice versa.

What other language is Welsh most like?

Welsh is what’s called a Brythonic language. Sometimes written as “Brittonic”, these languages descend from the Common Brittonic language that was spoken all over the island of Great Britain in the Iron Age and was taken to Brittany by Britons who emigrated there in the 5th and 6th centuries.

The only surviving modern Brittonic or Brythonic languages are Welsh, Cornish, and Breton. While it is true to say these three languages are closely related (they are usually termed p-Celtic languages), they are not really mutually intelligible unless some effort is made on the part of the speakers.

Do the Welsh have different languages?

There are two official languages in Wales – Welsh (Cymraeg) and English. English is the main official language, while Welsh has more limited official uses but is required in certain situations by law.

There are several dialects of Welsh, but there is only one Welsh language. It was estimated in 2021 that almost 30% of people in Wales could speak Welsh (that’s around 884 000 people).

This is thanks to extensive protests and efforts made to preserve and spread the language after many years of decline. By 2050, the Welsh government now has plans to triple this number of speakers. These efforts combined mean that Welsh is the only Celtic language not considered “endangered” by UNESCO.

There are several thousand people who speak a dialect of Welsh in Patagonia, Argentina. You will also find many Welsh speakers in the rest of the UK, the US, and Australia.

How many Welsh languages are there?

There is only one Welsh language. Confusingly, it has been referred to by several different terms throughout history. The English once called it “British” or “Cymric” as well as “Cambrian” or “Cambric”. In Welsh, the language is called Cymraeg.

It is worth noting that while most people would say there are northern (Gogledd) and southern (De) versions of the language, there are technically five dialects of Welsh. These are the Gwynedd dialect (Y Wyndodeg), the Powys dialect (Y Bowyseg), the Dyfed dialect (Y Ddyfedeg), the dialect of Gwent and Morgannwg (Y Wenhwyseg), and Patagonian Welsh.
