Gàidhlig, also known as Scottish Gaelic, has its origins in the Goidelic branch of the Celtic languages. The Celtic languages belong to the larger Indo-European language family.
The Goidelic languages, which include Gàidhlig, Irish Gaelic, and Manx Gaelic, developed from Old Irish, a language that was spoken in Ireland and parts of Scotland between the 6th and 10th centuries. It is believed that Goidelic speakers migrated from Ireland to Scotland, bringing their language with them.
Goidelic languages share a common ancestry with other Celtic languages, such as Brythonic (which includes Welsh, Cornish, and Breton). Together, Goidelic and Brythonic make up the two primary branches of the Insular Celtic languages.
As the Goidelic languages evolved separately in Ireland and Scotland, they developed distinct dialects and regional variations. Gàidhlig, in particular, developed its own unique characteristics and vocabulary, influenced by the history, culture, and geography of the Scottish Highlands and islands.
Over time, Gàidhlig has evolved and absorbed influences from various sources, including Norse, Latin, and English. Despite these influences, the language has maintained its distinct Celtic character and continues to be an important part of Scotland’s cultural and linguistic heritage.
