Most Welsh people only speak the language so that the English cannot understand what they are saying, a survey has confirmed.
More than 20,000 Welsh people were questioned after complaints were made about a phrase book.
Several entries in the book titled 'Useful Everyday Welsh' have caused controversy.
One, 'Lettus igoreri da dumbegnlishfukymgogogock' translates as 'I would prefer not to speak to this English chap.
Another statement: 'Imsa stupidycym englishcuntgogock' translated as 'Could you show me the way to the lavatory.'
Following criticism of the book the poll company Mori asked 21,764 Welsh speakers why they used the language.
More than 99 per cent said they routinely switched into Welsh when an English person came into a shop or pub.
A further 96 per cent agreed with the statement that 'Welsh is a dead language and learning it serves no practical purpose.'
Just over 72 per cent said they loathed the way the way Welsh sounded and felt it was a 'stupid language' which is sometimes associated with acts of bestiality involving farmyard animals.
