Common Brittonic

[10][11][12] Evidence from early and modern Welsh shows that Common Brittonic was significantly influenced by Latin during the Roman period, especially in terms related to the church and Christianity.

An inscription on a metal pendant (discovered there in 1979) seems to contain an ancient Brittonic curse:[19] "Adixoui Deuina Deieda Andagin Uindiorix cuamenai".

[3] The question of the extent to which this language was distinguished, and the date of divergence, from the rest of Brittonic, was historically disputed.

[3] Pritenic (also Pretanic and Prittenic) is a term coined in 1955 by Kenneth H. Jackson to describe a hypothetical Roman-era (1st to 5th centuries) predecessor to the Pictish language.

[3] Common Brittonic vied with Latin after the Roman conquest of Britain in 43 AD, at least in major settlements.

[3] The modern forms of Breton and Welsh are the only direct descendants of Common Brittonic to have survived fully into the 21st century.

[25] Cumbric and Pictish are extinct and today spoken only in the form of loanwords in English, Scots, and Scottish Gaelic.

Examples are: Basic words tor, combe, bere, and hele from Brittonic are common in Devon place-names.
