Through England, De facto and de jure and UNESCO

The Welsh Language (Wales) Measure 2011 gave the Welsh language official status in Wales. Welsh and English are de jure official languages of the Senedd (the Welsh parliament). According to the 2021 census, 538,300 usual residents in Wales aged three or over (17.8% of the population) were able to speak Welsh, while just over a quarter (25.1%) reported having some Welsh language skills.

Other surveys have produced higher figures: a survey in 2022–2023 found that 34% of people aged 16 or over could speak Welsh (of whom 18 per cent said they could speak Welsh, and 16 per cent said they had some Welsh speaking ability). In March 2026, other survey data estimated that 843,700 people (27.3%) aged three or over in Wales could speak Welsh.

Almost half of all Welsh speakers consider themselves fluent, while 20% are able to speak a fair amount. 56% of Welsh speakers speak the language daily, and 19% speak the language weekly. Since 1951, the number of Welsh speakers living in Wales has gone up, though the percentage of Welsh speakers with respect to the entire population of Wales has decreased every census year, with the exception of the 1991 and the 2001 UK Census.

The Welsh Government plans to increase the number of Welsh-language speakers to one million, and to double the daily use of the language, by 2050. Since 1980, the number of children attending Welsh-medium schools has increased, while the number going to Welsh bilingual and dual-medium schools has decreased. Welsh is considered the least endangered Celtic language by UNESCO.

History

The language of the Welsh developed from the language of Britons. The emergence of Welsh was not instantaneous and clearly identifiable. Instead, the shift occurred over a long period, with some historians claiming that it had happened by as late as the 9th century, with a watershed moment being that proposed by linguist Kenneth H. Jackson, the Battle of Dyrham, a military battle between the West Saxons and the Britons in 577 AD, which split the South Western British from direct overland contact with the Welsh.

Four periods are identified in the history of Welsh, with rather indistinct boundaries: Primitive Welsh, Old Welsh, Middle Welsh, and Modern Welsh. The period immediately following the language's emergence is sometimes referred to as Primitive Welsh, followed by the Old Welsh period – which is generally considered to stretch from the beginning of the 9th century to sometime during the 12th century. The Middle Welsh period is considered to have lasted from then until the 14th century, when the Modern Welsh period began, which in turn is divided into Early and Late Modern Welsh.

Late Modern Welsh, which is still the form spoken today started with William Morgan's 1588 translation of the Bible, and is still readable to most Welsh readers today. This Bible was the first Welsh translation of the whole Bible, and due to the Protestant Reformation in Wales emphasising literacy and vernacular reading of the Bible this standardised the language across Wales.

The first Welsh dictionary was the Antiquae linguae Britannicae as a Welsh-Latin dictionary published in 1632 by John Davies, who was an assistant in translating the 1588 Bible. The first Welsh-English dictionary was published in fifteen parts between 1770 and 1794 by John Walters based on the work of William Gambold.

The word Welsh is a descendant, via Old English wealh, wielisc, of the Proto-Germanic word *Walhaz, which was derived from the name of the Celtic people known to the Romans as Volcae and which came to refer to speakers of Celtic languages, and then indiscriminately to the people of the Western Roman Empire. In Old English the term went through semantic narrowing, coming to refer to either Britons in particular or, in some contexts, slaves. The plural form Wēalas evolved into the name for their territory, Wales.

The modern names for various Romance-speaking people in Continental Europe (e.g. Walloons, Valaisans, Vlachs/Wallachians, and Włosi, the Polish name for Italians) have a similar etymology. The Welsh term for the language, Cymraeg, descends from the Brythonic word combrogi, meaning 'compatriots' or 'fellow countrymen'.

Origins

Welsh evolved from Common Brittonic, the Celtic language spoken by the ancient Celtic Britons. Classified as Insular Celtic, the British language probably arrived in Britain during the Bronze Age or Iron Age and was probably spoken throughout the island south of the Firth of Forth. During the Early Middle Ages the British language began to fragment due to increased dialect differentiation, thus evolving into Welsh and the other Brittonic languages. It is not clear when Welsh became distinct.

Linguist Kenneth H. Jackson has suggested that the evolution in syllabic structure and sound pattern was complete by around 550 AD, and labelled the period between then and about 800 AD "Primitive Welsh". This Primitive Welsh may have been spoken in both Wales and the Hen Ogledd ('Old North') – the Brittonic-speaking areas of what are now northern England and southern Scotland – and therefore may have been the ancestor of Cumbric as well as Welsh. Jackson, however, believed that the two varieties were already distinct by that time.

The earliest Welsh poetry – that attributed to the Cynfeirdd or "Early Poets" – is generally considered to date to the Primitive Welsh period. However, much of this poetry was supposedly composed in the Hen Ogledd, raising further questions about the dating of the material and language in which it was originally composed. This discretion stems from the fact that Cumbric was widely believed to have been the language used in Hen Ogledd. An 8th-century inscription in Tywyn shows the language already dropping inflections in the declension of nouns.

Janet Davies proposed that the origins of the Welsh language were much less definite; in The Welsh Language: A History, she proposes that Welsh may have been around even earlier than 600 AD. This is evidenced by the dropping of final syllables from Brittonic: *bardos 'poet' became bardd, and *abona 'river' became afon. Though both Davies and Jackson cite minor changes in syllable structure and sounds as evidence for the creation of Old Welsh, Davies suggests it may be more appropriate to refer to this derivative language as Lingua Britannica rather than characterising it as a new language altogether.

Primitive Welsh

The argued dates for the period of "Primitive Welsh" are widely debated, with somehistorians' suggestions differing by hundreds of years.

Old Welsh

The next main period is Old Welsh (Hen Gymraeg, 9th to 11th centuries); poetry from both Wales and Scotland has been preserved in this form of the language. As Germanic and Gaelic colonisation of Britain proceeded, the Brittonic speakers in Wales were split off from those in northern England, speaking Cumbric, and those in the southwest, speaking what would become Cornish, so the languages diverged. Both the works of Aneirin (Canu Aneirin, c. 600) and the Book of Taliesin (Canu Taliesin) were written during this era.

Middle Welsh

Middle Welsh (Cymraeg Canol) is the label attached to the Welsh of the 12th to 14th centuries, of which much more remains than for any earlier period. This is the language of nearly all surviving early manuscripts of the Mabinogion, although the tales themselves are certainly much older. It is also the language of the existing Welsh law manuscripts. Middle Welsh is reasonably intelligible to a modern-day Welsh speaker.

Modern Welsh

The Bible translations into Welsh helped maintain the use of Welsh in daily life, and standardised spelling. The New Testament was translated by William Salesbury in 1567, and the complete Bible by William Morgan in 1588. Modern Welsh is subdivided into Early Modern Welsh and Late Modern Welsh. Early Modern Welsh ran from the 15th century through to the end of the 16th century, and the Late Modern Welsh period roughly dates from the 16th century onwards. Contemporary Welsh differs greatly from the Welsh of the 16th century, but they are similar enough for a fluent Welsh speaker to have little trouble understanding it.

During the Modern Welsh period, there has been a decline in the popularity of the Welsh language: the number of Welsh speakers declined to the point at which there was concern that the language would become extinct. During industrialisation in the late 19th century, immigrants from England led to the decline in Welsh speakers particularly in the South Wales Valleys. Welsh government processes and legislation have worked to increase the proliferation of the Welsh language, for example through education.
