The Breton and Welsh languages have a common origin but
have evolved over the centuries. They are both Celtic languages.
Invasions, repressions and close proximity to other languages have
caused them to change. The evolution of Welsh and Breton can be divided
into the following stages:
The Celtic origin
Old-Breton and Old-Welsh: from the 5th century
Middle-Breton and Middle -Welsh: from the 11th century
Modern Breton and Modern Welsh: from the end of the 16th
Contemporary Breton and Welsh: since the 20th century
survival of the Welsh and the Breton over centuries is outstanding. We
can not let them die!
Welsh and Breton are to entirely languages but we can find some
similarities in the grammar and vocabulary.
