NISL is described as being related to Irish Sign Language (ISL) at the syntactic level while the lexicon is based on British Sign Language (BSL) and American Sign Language (ASL).^{[citation needed]}

A number of practitioners see Northern Ireland Sign Language as a distinct and separate language from both BSL and ISL though "many 'Anglo-Irish'^{[further explanation needed]} 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.
