BANZSL, or British, Australian and New Zealand Sign Language, is the language of which British Sign Language (BSL), Auslan and New Zealand Sign Language (NZSL) may be considered dialects. These three languages may technically be considered dialects of a single language (BANZSL) due to their use of the same grammar, manual alphabet, and the high degree of lexical overlap. The term BANZSL was coined by Trevor Johnston and Adam Schembri.
