Cornish road signs could soon be printed in both English and Cornish as part of a bid to promote the region's traditional language.
Cornwall Council will adopt a new Cornish Language policy, which will demand that street signs are written in both languages.
The changes will only apply to new or replacement signs.
Around 300 people are believed to be fluent in Cornish, while a few thousand can recognise a few words.
However, councillor Dick Cole said the decision could boost the Cornish economy.
"Cornwall's uniqueness is its Celtic heritage and we have to promote that to attract more overseas visitors," he said.
The decision has not been given a universal welcome, though.
Councillor Morwenna Williams said: 'This will not be welcomed in my part of the county. Some people in Cornwall will find this ridiculous and unnecessary.'
