British Sign Language

Although the United Kingdom and the United States share English as the predominant oral language, British Sign Language is quite distinct from American Sign Language (ASL) - having only 31% signs identical, or 44% cognate. BSL is also distinct from Irish Sign Language (ISL) (ISG in the ISO system) which is more closely related to French Sign Language (LSF) and ASL.
