Particles in Korean: 은/는, 이/가, and 을/를

What you’ll practice

Particles can completely change what a sentence emphasizes, so this quiz targets the most common trio: 은/는 (topic), 이/가 (subject), and 을/를 (object). You’ll choose the particle that best matches the intended meaning and context.

Each question is multiple-choice with 4 options and no timer, so you can slow down and reason through nuance instead of rushing. You can also choose your question count and difficulty before starting, making it easy to do a quick drill or a longer study session.

Common pitfalls to watch for

Many learners overuse 은/는 as a default “subject marker,” or swap 이/가 and 은/는 without considering contrast, new information, or emphasis. Another frequent mistake is forgetting that 을/를 marks the object even when English word order makes it feel obvious.

• Confusing topic (은/는) with grammatical subject (이/가)
• Missing contrast use of 은/는 ("as for...", comparisons)
• Using 이/가 when the sentence is about a known topic
• Dropping 을/를 incorrectly in sentences where clarity matters
• Forgetting particle changes after 받침 (은/는, 이/가, 을/를)

How difficulty is balanced

The mixed difficulty setting blends straightforward particle selection with context-heavy sentences where more than one option looks tempting. Easier items reinforce the core rules, while harder ones test emphasis, contrast, and information structure - so your accuracy improves without the quiz feeling repetitive.
