There are several manual alphabets in use around the world that employ two hands to represent the letters of an alphabet, I have chosen to learn the BANZSL or British, Australian and New Zealand Sign Language. The BANZSL group of sign language has been used in British Sign Language and Auslan since at least the 19th century, and in New Zealand Sign Language since the 1970s. Variations of this alphabet are also used in dialects of Indo-Pakistani Sign Language.
I decided to incorporate this into my 32 Things as it felt in line with learning the Phonetic Alphabet. Learning the alphabet is just a start, I would like to learn other gestures and words as I have always been interested in it.
