Celtic was the original language in the West Country, specifically in Devon. It is said that the Celtic language was spoken in this area until the middle ages13, but some traces can still be found in the current dialects.
Except for the Cornish dialect, the West Country dialects have a slower rhythm to speech because of the vowel length and, like in Dutch, some letters in words can be replaced with closely related letters: /s/ for /z/ and /f/ for /v/.
