Japanese grammar is the system of rules that governs how words and sentences are structured in the Japanese language. It is characterized by its use of particles, which are small words that indicate the grammatical function of a word in a sentence. For example, the particle は (wa) marks the topic, while を (o) indicates the direct object. In Japanese, the typical sentence structure follows a Subject-Object-Verb (SOV) order. This means that the verb usually comes at the end of the sentence. Additionally, Japanese often omits subjects and objects when they are understood from context, making it a context-driven language.
