Japanese Grammar (日本語 文法)

Now that we have learned how to write Japanese, we can begin going over the basic grammatical structure of the language. This section primarily covers all the parts of speech: nouns, adjectives, verbs, and adverbs. It will also describe how to integrate the various parts of speech into a coherent sentence by using particles. By the end of this section, you should have an understanding of how basic sentences are constructed.
