Chinese written language is a logographic system in which a unique symbol, character, is used to represent lexical morphemes and each character maps to one morpheme rather than to an individual phonemic unit of the spoken language.

The Clavis Sinica learning system is designed to assist current learners of Chinese to have a smoother study experience and act as an introductory lesson for prospective students.

  Just as in English, words in Chinese are the basic element for a sentence. Words (with no space in between) plus punctuation form a normal sentence in Chinese. In English, the length of words varies from one letter to over ten letters; there is not a clue to trace the meanings' relevance to the length of the words.

  As a wonderful production, Chinese character was brought to us through the 5000-year long history and culture of China. Nowadays, many people are learning Chinese character all over the world.
