Celtic cognates

The six Celtic languages currently spoken are divided into two ranches: Goidelic, and Brythonic. The former branch consists of Irish, Manx and Scottish Gaelic, while the latter branch includes Welsh, Cornish and Breton. While there are many similarities between the languages in each branch, there are fewer similiarities between the two branches as they have had thousands of years to grow apart. However, they do still have quite a few words that are related (cognates).

Please note

I am not a native speaker of any of these languages, but have been studying them, on and off, for quite a few years. I speak Welsh and Irish more or less fluently, can get by in Scottish Gaelic and Manx, and have a basic knowledge of Cornish and Breton.

By putting this information together here, my aim is to improve my knowledge of these languages and to share that knowledge with others. If you have corrections, questions or suggestions, please contact me.
