A number of practitioners see Northern Ireland Sign Language as a distinct and separate language from both BSL and ISL though "many 'Anglo-Irish' Northern Irish signers argue against the use of the acronym NISL and believe that while their variety is distinct, it is still a part of British Sign Language."
As of March 2004[update] the British Government recognises only British Sign Language and Irish Sign Language as the official sign languages used in Northern Ireland.
^a Sign-language names reflect the region of origin. Natural sign languages are not related to the spoken language used in the same region. For example, French Sign Language originated in France, but is not related to French.
