Hello! The difference between Celtic and Gaelic is an important one to understand, especially for those with a college level education. Celtic refers to a group of languages that are related to each other and are spoken in parts of Europe, including Ireland, Scotland, Wales, Cornwall, the Isle of Man, and Brittany in France. Gaelic is a specific language within the Celtic language family. It is the native language of Ireland and Scotland and is also known as Irish or Scottish Gaelic. Celtic languages are divided into two branches: Goidelic (Gaelic) and Brythonic (Welsh). The Goidelic branch includes Irish Gaelic, Scottish Gaelic, and Manx (spoken on the Isle of Man). The Brythonic branch includes Welsh, Cornish (spoken in Cornwall), and Breton (spoken in Brittany). Gaelic has been spoken in Ireland since at least the 4th century AD. It was once spoken throughout much of Scotland as well but has since been replaced by English as the primary language there. Today it is still spoken by about 1 million people in Ireland and 60-80 thousand people in Scotland. In terms of grammar and vocabulary, Irish Gaelic is very similar to Scottish Gaelic but there are some differences between them. For example, Irish uses more verbal nouns than Scottish does while Scottish uses more prepositions than Irish does. Additionally, there are some pronunciation differences between the two dialects such as how vowels are pronounced differently in each dialect. Overall, Celtic refers to a group of related languages while Gaelic specifically refers to the Goidelic branch which includes Irish Gaelic and Scottish Gaelic. While they share many similarities they also have some distinct differences such as grammar structure and pronunciation which make them unique from one another.
