Korean particles and grammar, side by side.

Every Korean particle, grammar pattern and hanja in one place, with real examples, the mistakes learners actually make, and practice.

고양이쥐봤어요.

Try it. Drop a particle in.

고양이 is a cat. 쥐 is a mouse. 봤어요 means "saw". Until you attach a particle, there is no way to tell who saw whom.

What are Korean particles?

Korean particles (조사, josa) are short endings that attach to a word and tell you its job in the sentence. English shows who did what mostly through word order; Korean shows it with particles, so words can move around and the meaning stays clear.

Some particles mark a role, like the subject, the object or the topic. Others add a meaning, like "too", "only", "even" or "from". Grammar patterns work the same way on verbs: 고 싶다 (go sipda) turns "go" into "want to go".

  • 고양이가goyangigathe cat (does something)subject
  • 고양이를goyangireulthe cat (has something done to it)object
  • 고양이는goyangineunas for the cat…topic
  • 고양이도goyangidothe cat tootoo, also

Start here: the beginner Korean particles

These are the particles and patterns you need to build a basic sentence. Each one has its own lesson with examples, and when you're ready there are 73 more in the library.

Next: comparing, giving reasons, joining ideas

Once a basic sentence feels easy, these are the ones you'll want next.

Built by a learner, free for every learner

KoreanParticles started because there was no single place that explained every particle and grammar point simply. It's a free atlas of Korean grammar, and a tribute to the language. Read why I built it.

Also by me: Korean Wisdom, a Korean proverb on every new tab.
