Modern Celtic languages are a branch of the Celtic language family, which includes Irish, Scottish Gaelic, Welsh, Cornish, and Breton. These languages are primarily spoken in regions of the British Isles and Brittany in France. They have distinct grammatical structures and vocabulary, reflecting their unique cultural histories. Despite their rich heritage, modern Celtic languages face challenges, including declining numbers of speakers and limited use in daily life. Efforts are underway to revitalize these languages through education, media, and community initiatives, aiming to preserve their cultural significance for future generations.
