Grammar Rule in 30 Seconds
The particle を (wo) marks the direct object of an action, showing exactly what is being acted upon.
- Use を after the direct object: {本|ほん}を{読|よ}む (Read a book).
- It only marks objects of transitive verbs: {水|みず}を{飲|の}む (Drink water).
- Never use を with intransitive verbs like 'go' or 'exist': {学校|がっこう}へ{行|い}く (Go to school).
Overview
o in modern Japanese, though romanized as wo) is one of the most fundamental particles in Japanese. It marks the direct object of a verb — the thing that receives the action. If someone eats sushi, sushi is the object being eaten, so it gets を.book gets を. This particle appears in almost every sentence that has a transitive verb (a verb that takes an object). Without を, listeners would not know what is being acted upon.I eat sushi — sushi comes after the verb). In Japanese, the particle を does this job regardless of word order, though the standard order is Subject + Object + Verb (SOV). You will also see を used with verbs of motion to indicate a path or route traversed: 公園を歩く (walk through the park), 橋を渡る (cross the bridge).path usage is important and often surprises learners. Note that を is ONLY written with the hiragana を — it is never used as a regular syllable in words, only as a particle. Learning to use を naturally is a major milestone in Japanese because it unlocks the ability to form complete, meaningful sentences with transitive verbs.Meanings
