Ebook: Oxford Japanese Grammar & Verbs: clear and simple explanations

The Japanese Grammar and Verbs is part of a series of Oxford
grammars of modern languages. It includes information on a wide
number of structures likely to be encountered in the first few years
of studying Japanese at school or college and contains everything
that is essential up to A level. For those living and working in
Japan, it presents commonly seen and heard material. It is
designed to serve both as a source of information in itself, and as a
supplementary reference for users of textbooks which may not
cover grammar topics adequately.
