The usual approach to expanding vocabulary is to use a topic /situation based technique. This works well if the topics/situations are ones that the student may use, or is interested in them. However it is by its nature random in the choice of words it introduces and furthermore the problem of how the student can quickly learn how to write all these different characters is never seriously addressed. There are however, other approaches that could be used, that could offer the student a better investment on the time they spend, but up to now they have not been explored by Teachers, This book introduces one such approach, by looking at and understanding repetition in Mandarin Chinese. This book will not be looking at repetition as in ?? ?? or in phrases such as ???? etc What we will be focusing on is repetition of meaning in a word that uses two different characters in Chinese. We think this could open up new ways of thinking about the language for students studying Chinese.
