As the Cornish language disappeared, so the people of Cornwall underwent a process of English assimilation. However a Celtic revival which started in the early 20th century has revitalised the Cornish language and the Cornish Celtic heritage.

Yes, the people of Cornwall speak English as their primary and daily language. However, many residents speak with a distinct Cornish dialect (Anglo-Cornish), which features unique vocabulary, grammatical structures, and a melodic accent influenced by the ancient Celtic Cornish language. For example, you might hear "Proper job!" for something done well. In 2026, there is also a significant cultural movement to revive Kernewek (the Cornish language). While you will see bilingual road signs and may hear Kernewek spoken in cultural ceremonies or by enthusiasts, it is not used for general commerce or daily life by the majority. To a visitor's ear, the Cornish accent is often described as "rhythmic" and "rhotic" (similar to a West Country burr), but it is perfectly intelligible to any English speaker. The language is a point of immense local pride, reflecting the region's unique identity as one of the six Celtic nations.
