If you're one of the millions of Korean learners who have struggled to understand exactly how the Korean particles 은, 는, 이 and 가 work, this will be a great one-stop guide for you! People who learn Korean as their mother tongue can distinguish their specific roles and various usages at a very young age, but for learners who study Korean as a foreign language, these topic/subject markers can be a bit tricky to understand.

Here's the gist of this video:
- 은 and 는 are "topic markers" and show you what the topic of the sentence is.
- 이 and 가 are "subject markers" and show you the direct subject of the verb that is being used in the sentence.
- 은/는 also shows contrast and change of scene/narrative.
- In compound sentences, such as "The movie I watched was fun.", you can see 은/는 and 이/가 being used together.

But for a better understanding, we recommend that you watch the full video (more than once if necessary) and pay close attention to the detailed examples.
