The Goidelic /ɡɔɪˈdɛlɪk/ or Gaelic languages (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.
