Celtic languages

The celtic languages are a group of languages descended from proto-celtic (and a branch of the indo-Europoean language family).

The celtic languages are divided into two groups: brittonic and Goidelic. Britonnic (or British Celtic languages) are all descended from the root language Common Britonnic spoken in Britain and Brittany.
