The system of Blissymbolics has several features which makes it a preferred means of communication for nonspeaking persons, for persons with limited literacy skills, and for persons who are ready and eager to use Bliss to communicate with persons whatever their language background may be.
Blissymbolics is a language with a wide vocabulary, a grammar which allows for sentences in past, future and present tenses, and markers for possession, plurality, questions and commands.
There are many strategies within the system of Blissymbolics which enable the user to create new symbols. It is a totally generative system with each new symbol interpretable by the receiver through analysing the component parts. In the same way that letters represent sounds that are used to create words in print, meaning-based Bliss-characters are sequenced to define the meaning of each compound symbol or Bliss-word.
The full current vocabulary is built from around 1200 such semantic characters. However, since these Bliss-characters are built from a limited number of elements, called key symbols, the learner need only master the meaning of approximately a maximum of 100 to 120 elements.
After all, it is important to remember that Bliss can be introduced and practically used from a very simple and early level, with a wide horizon for language and literacy development at hand.
