Manx language in the context of First-foot

The Celtic languages (/ˈkɛltɪk/ KEL-tik) are a branch of the Indo-European language family, descended from the hypothetical Proto-Celtic language. The term "Celtic" was first used to describe this language group by Edward Lhuyd in 1707, following Paul-Yves Pezron, who made the explicit link between the Celts described by classical writers and the Welsh and Breton languages.

During the first millennium BC, Celtic languages were spoken across much of Europe and central Anatolia. Today, they are restricted to the northwestern fringe of Europe and a few diaspora communities. There are six living languages: the four continuously living languages Breton, Irish, Scottish Gaelic and Welsh, and the two revived languages Cornish and Manx. All are minority languages in their respective countries, though there are continuing efforts at revitalisation. Welsh is an official language in Wales and Irish is an official language across the island of Ireland and of the European Union. Welsh is the only Celtic language not classified as endangered by UNESCO. The Cornish and Manx languages became extinct in modern times but have been revived. Each now has several hundred second-language speakers.

The Gaels (/ɡeɪlz/ GAYLZ; Irish: Na Gaeil [n̪ˠə ˈɡeːlʲ]; Scottish Gaelic: Na Gàidheil [nə ˈkɛː.al]; Manx: Ny Gaeil [nə ˈɡeːl]) are an Insular Celtic ethnic group native to Ireland, Scotland, and the Isle of Man, and historically, Iceland and the Faroe Islands. They are associated with the Gaelic languages: a branch of the Celtic languages comprising Irish, Manx, and Scottish Gaelic.

Gaelic language and culture originated in Ireland, extending to Dál Riata in western Scotland. In antiquity, the Gaels traded with the Roman Empire and also raided Roman Britain. In the Middle Ages, Gaelic culture became dominant throughout the rest of Scotland and the Isle of Man. There was also some Gaelic settlement in Wales, as well as cultural influence through Celtic Christianity. In the Viking Age, small numbers of Vikings raided and settled in Gaelic lands, becoming the Norse-Gaels. In the 9th century, Dál Riata and Pictland merged to form the Gaelic Kingdom of Alba (Scotland). Meanwhile, Gaelic Ireland was made up of several kingdoms, with a High King often claiming lordship over them.

Castletown (Manx: Balley y Chashtal, pronounced [ˈbalʲə ˈxaʃtʃəl]) is a town in the Isle of Man, geographically within the historical parish of Malew but administered separately. Lying at the south of the island, it was the Manx capital until 1869. The centre of town is dominated by Castle Rushen, a well-preserved medieval castle, originally built for a Viking king.

The Irish Sea is a 46,007 km (17,763 sq mi) body of water that separates the islands of Ireland and Great Britain. It is linked to the Celtic Sea in the south by St George's Channel and to the Inner Seas off the West Coast of Scotland in the north by the North Channel. Anglesey, North Wales, is the largest island in the Irish Sea, followed by the Isle of Man. The term Manx Sea may occasionally be encountered (Welsh: Môr Manaw, Irish: Muir Meann Manx: Mooir Vannin, Scottish Gaelic: Muir Mhanainn).

On its shoreline are Scotland to the north, England to the east, Wales to the southeast, Northern Ireland and the Republic of Ireland to the west. The Irish Sea is of significant economic importance to regional trade, shipping and transport, as well as fishing and power generation in the form of wind power and nuclear power plants. Annual traffic between Great Britain and Ireland is over 12 million passengers and 17 million tonnes (17,000,000 long tons; 19,000,000 short tons) of traded goods.

Breton (/ˈbrɛtən/, BRET-ən; French: [bʁətɔ̃]; endonym: brezhoneg [bʁeˈzɔ̃ːnɛk] or [bɾəhɔ̃ˈnek] in Morbihan) is a Southwestern Brittonic language of the Celtic language group spoken in Brittany, part of modern-day France. It is the only Celtic language still in use on the European mainland.

Breton is an Insular Celtic language that was brought from Great Britain to Brittany by migrating Britons during the Early Middle Ages, making Breton most closely related to Cornish, another Southwestern Brittonic language. Welsh and the extinct Cumbric, both Western Brittonic languages, are more distantly related, and the Goidelic languages (Irish, Manx, Scottish Gaelic) have a slight connection due to both of their origins being from Insular Celtic.

The morphology of the Welsh language shows many characteristics perhaps unfamiliar to speakers of English or continental European languages like French or German, but has much in common with the other modern Insular Celtic languages: Irish, Scottish Gaelic, Manx, Cornish, and Breton. Welsh is a moderately inflected language. Verbs conjugate for person, tense and mood with affirmative, interrogative and negative conjugations of some verbs. A majority of prepositions inflect for person and number. There are few case inflections in Literary Welsh, being confined to certain pronouns.

Modern Welsh can be written in two varieties – Colloquial Welsh or Literary Welsh. The grammar described on this article is for Literary Welsh.

Modern Welsh can be written, and spoken, in several levels of formality, for example colloquial or literary, as well as different dialects. The grammar described in this article is for Colloquial Welsh, which is used for speech and informal writing. Literary Welsh is closer to the form of Welsh used in William Morgan's 1588 translation of the Bible and can be seen in formal writing. It does not reflect the spoken language presented here.

The Norse–Gaels (Old Irish: Gall-Goídil; Irish: Gall-Ghaeil; Scottish Gaelic: Gall-Gàidheal; Manx: Goal-Gael, 'foreigner-Gaels') were a people of mixed Gaelic and Norse ancestry and culture. They emerged in the Viking Age, when Vikings who settled in Ireland and in Scotland became Gaelicised and intermarried with Gaels. The Norse–Gaels dominated much of the Irish Sea and Scottish Sea regions from the 9th to 12th centuries. They founded the Kingdom of the Isles (which included the Hebrides and the Isle of Man), the Kingdom of Dublin, the Lordship of Galloway (which is named after them), and briefly ruled the Kingdom of York (939–944 AD). The most powerful Norse–Gaelic dynasty were the Uí Ímair or Ivar dynasty.

Over time, the Norse–Gaels became ever more Gaelicised and disappeared as a distinct group. However, they left a lasting influence, especially in the Isle of Man and Outer Hebrides, where most placenames are of Norse–Gaelic origin. Several Scottish clans have Norse–Gaelic roots, such as Clan MacDonald, Clan MacDougall and Clan MacLeod. The elite mercenary warriors known as the gallowglass (gallóglaigh) emerged from these Norse–Gaelic clans and became an important part of Irish warfare. The Viking longship also influenced the Gaelic birlinn and longa fada, which were used extensively until the 17th century. Norse–Gaelic surnames survive today and include MacIvor, MacAskill, and [Mac]Cotter.

The Isle of Man (Manx: Mannin [ˈmanɪnʲ], also Ellan Vannin [ˈɛlʲan ˈvanɪnʲ]), or Mann (/mæn/ man), is a self-governing British Crown Dependency in the Irish Sea, between Great Britain and Ireland. As head of state, Charles III holds the title Lord of Mann and is represented by a Lieutenant Governor. The government of the United Kingdom is responsible for the Isle of Man's military defence and represents it abroad, but the Isle of Man still has a separate international identity.

Humans have lived on the island since before 6500 BC. Gaelic cultural influence began in the 5th century AD, when Irish missionaries following the teaching of St Patrick began settling the island, and the Manx language, a branch of the Goidelic languages, emerged. In 627, King Edwin of Northumbria conquered the Isle of Man along with most of Mercia. In the 9th century, Norsemen established the thalassocratic Kingdom of the Isles, which included the Hebrides and the Northern Isles, along with the Isle of Man as the southernmost island. Magnus III, King of Norway from 1093 to 1103, reigned as King of Man and the Isles between 1099 and 1103.

Tanistry was a system of inheritance practised by the Gaelic nobilities of Ireland, the Isle of Man, and parts of modern Scotland. It was distinctive in having an elected heir known as the tanist (Irish: tánaiste; Scottish Gaelic: tànaiste; Manx: tanishtey). This system was used to select the Chiefs of the Name (head of a clan) and the rulers of the various Gaelic kingdoms in Ireland and in Scotland.

When the chief or king died they were immediately succeeded by the tanist, who had typically been elected years earlier. A new election was then held to select the next tanist. This differs from other systems of elective inheritance, in that an heir was elected in advance of a vacancy, not after the vacancy arose. Valid candidates for the election were restricted to male members of the title holder's sept (extended family); the exact eligibility criteria differed between Ireland and Scotland. The electorate was identical to the set of valid candidates i.e. potential heirs would select a tanist from among themselves.

Scottish Gaelic (/ˈɡælɪk/ GAL-ik; endonym: Gàidhlig [ˈkaːlɪkʲ] ), also known as Scots Gaelic or simply Gaelic, is a Celtic language native to the Gaels of Scotland. As a member of the Goidelic branch of Celtic, Scottish Gaelic, alongside both Irish and Manx, developed out of Old Irish. It became a distinct spoken language sometime in the 13th century in the Middle Irish period, although a common literary language was shared by the Gaels of both Ireland and Scotland until well into the 17th century. Most of modern Scotland was once Gaelic-speaking, as evidenced especially by Gaelic-language place names.

In the 2011 census of Scotland, 57,375 people (1.1% of the Scottish population, three years and older) reported being able to speak Gaelic, 1,275 fewer than in 2001. The highest percentages of Gaelic speakers were in the Outer Hebrides. Nevertheless, there is a language revival, and the number of speakers of the language under age 20 did not decrease between the 2001 and 2011 censuses. In the 2022 census of Scotland, it was found that 2.5% of the Scottish population had some skills in Gaelic, or 130,161 persons. Of these, 69,701 people reported speaking the language, with a further 46,404 people reporting that they understood the language, but did not speak, read, or write in it.

The Goidelic (/ɡɔɪˈdɛlɪk/ goy-DEL-ik) or Gaelic languages (/ˈɡeɪlɪk/ GALE-ik; Irish: teangacha Gaelacha; Scottish Gaelic: cànanan Goidhealach; Manx: çhengaghyn Gaelgagh) form one of the two groups of Insular Celtic languages, the other being the Brittonic languages.

Goidelic languages historically formed a dialect continuum stretching from Ireland through the Isle of Man to Scotland. There are three modern Goidelic languages: Irish (Gaeilge), Scottish Gaelic (Gàidhlig), and Manx (Gaelg). Manx died out as a first language in the 20th century but has since been revived to some degree.

Middle Irish, also called Middle Gaelic (Irish: An Mheán-Ghaeilge, Scottish Gaelic: Meadhan-Ghàidhlig, Manx: Mean Ghaelg), is the Goidelic language which was spoken in Ireland, most of Scotland and the Isle of Man from c. 900–1200 AD; it is therefore a contemporary of Late Old English and Early Middle English. The modern Goidelic languages—Modern Irish, Scottish Gaelic and Manx Gaelic—are all descendants of Middle Irish.

Old Irish, also called Old Gaelic (endonym: Goídelc; Irish: Sean-Ghaeilge; Scottish Gaelic: Seann-Ghàidhlig; Manx: Shenn Yernish or Shenn Ghaelg), is the oldest form of the Goidelic/Gaelic language for which there are extensive written texts. It was used from c. 600 to c. 900. The main contemporary texts are dated c. 700–850; by 900 the language had already transitioned into early Middle Irish. Some Old Irish texts date from the 10th century, although these are presumably copies of texts written at an earlier time. Old Irish is forebear to Modern Irish, Manx and Scottish Gaelic.

Old Irish is known for having a particularly complex system of morphology and especially of allomorphy (more or less unpredictable variations in stems and suffixes in differing circumstances), as well as a complex sound system involving grammatically significant consonant mutations to the initial consonant of a word. Apparently, neither characteristic was present in the preceding Primitive Irish period, though initial mutations likely existed in a non-grammaticalised form in the prehistoric era.

Celtic studies or Celtology is the academic discipline occupied with the study of any sort of cultural output relating to the Celtic-speaking peoples (i.e. speakers of Celtic languages). This ranges from linguistics, literature and art history, archaeology and history, the focus lying on the study of the various Celtic languages, living and extinct. The primary areas of focus are the six Celtic languages currently in use: Irish, Scottish Gaelic, Manx, Welsh, Cornish, and Breton.

As a university subject, it is taught at a number of universities, most of them in Ireland, the United Kingdom, or France, but also in the United States, Canada, Australia, Germany, Poland, Austria and the Netherlands.

Malew (/məˈluː/ mə-LOO; Manx: Malew) is one of the seventeen parishes of the Isle of Man.

It is located in the south of the Island (part of the traditional South Side division) in the sheading of Rushen.

Castle Rushen (Manx: Cashtal Rosien) is a medieval castle located in the Isle of Man's historic capital, Castletown, in the south of the Island. It towers over the Market Square to the south-east and the harbour to the north-east. The castle is amongst the best examples of medieval castles in Europe and is still in use as a museum and educational centre.
