The toponym Cornouaille was established in the early Middle Ages in the southwest of the Breton peninsula. Prior to this, following the withdrawal of Rome from Britain, British migrants from what is now
Devon had established the region of
Domnonea (in Breton) or
Domnonée (in French) in the north of the peninsula, taken from the Latin
Dumnonia. The first mention in surviving records of a
Cornouaille-related name was made between 852 and 857, when
Anaweten, bishop of
Saint-Corentin at
Quimper Cathedral, took over the
Cornugallensis under the order of
Nominoe,
Duke of Brittany and
Tad ar Vro. The names Cornwall and Cornouaille, like the surname Cornwallis, are from
Corn-wealas. The first element is from the name of a Brythonic tribe Latinized as
Cornovii, meaning 'peninsula people', from the Celtic
kernou, 'horn, headland', from
PIE *ker- 'uppermost part of the body, head, horn, top, summit'. The second element is the
Anglo-Saxon suffix
-wealas, from
walh, a word used by the Germanic speakers for 'a non-Germanic foreigner', especially Celtic speakers but also sometimes used for
Romance-language speakers.
Walh is an element found in the words and names
walnut,
Walloon,
Wales,
Wallasey,
Waleswood,
Wallachia,
Wallace,
Walcheren, and
Walsh. A
Corn-/Kern- name was used in reference to resettlement by a second wave of Celts from Great Britain in formerly Dumnonian-seized lands. This is related to the distinction made in French between
Grande-Bretagne (Great Britain) and
Bretagne (Brittany) – Brittany having originally been thought of as a British colony (and the second such in the same area). Cornouaille is known in
Breton as Kernev or
Bro-Gernev, and in
Latin as
Cornugallia or
Cornubia. In Cornish,
Kernev is written
Kernow, but the name is pronounced the same in both languages. ==History==
