Cornish is a Southwestern Brittonic language of the Celtic family, primarily spoken in Cornwall, UK. It experienced a decline in speakers between the 13th and 18th centuries and was declared extinct in the late 18th century. However, there's been a revival effort, with a growing number of speakers and those learning the language, according to the BBC and the Cornish Language Fellowship.
The revival focuses on reconstructing and standardising the language, including coining new words for modern concepts, and creating educational material in order to teach Cornish to others. A number of orthographies have been proposed in the past 100 years, but in 2008 a common orthography was adopted. In 2010 a new milestone was reached when UNESCO altered its classification of Cornish, stating that its previous label of "extinct" was no longer accurate.
In 1981, the Breton library Preder edited Passyon agan arluth (Passion of our lord), a 15th-century Cornish poem. The first complete translation of the Bible into Cornish, translated from English, was published in 2011. Another Bible translation project translating from original languages is underway. The New Testament and Psalms were made available online on YouVersion (Bible.com) and Bibles.org in July 2014 by the Bible Society.
