Japanese grammar is an essential part of learning the Japanese language.

It is the set of rules that govern the way words are combined to form sentences in the Japanese language. Japanese grammar is known for its complex system of particles, which are small words that are added to the end of nouns or verbs to indicate the grammatical function of the word in the sentence.
