Blissymbolics is a semantic graphical language that is currently composed of more than 5000 authorized symbols - Bliss-characters and Bliss-words. It is a generative language that allows its users to create new Bliss-words as needed. It is used by individuals with severe speech and physical impairments around the world, but also by others for language learning and support, or just for the fascination and joy of this unique language representation.
Blissymbolics Communication International is a non-profit, charitable organization that holds the perpetual, worldwide rights for the use and publication of Blissymbols. BCI provides leadership in the development of the system of Blissymbolics. Blissymbolics is offered for all to use under a choice of two generous licensing schemes - either a free, copyleft license, or a proprietary license agreement.
