Scottish Gaelic ( 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.
