Topic particle

The Korean text pronunciation feature (🔊) is only available for Chrome, Edge, Safari, and Opera browsers.

Noun or Pronoun + /

은 - if a word ends in a consonant, 는 - if ends in a vowel

In the examples from previous lessons, sometimes -이/-가 and sometimes -은/-는 were attached to nouns. It's important not to confuse them with each other, as these particles are not interchangeable and not synonyms. They have completely different functions in a sentence.

Particles -은 / -는, which are also called the topic particles in many Korean textbooks, are helping particles that can serve multiple functions in a sentence. In this lesson, we'll only talk about one function since it's too early to talk about other functions. I'll explain them in this lesson.

1. Use -은 / -는 to set or highlight the main topic.
It can be translated as "as for", "with regard to".

Often, the particles -은 / -는 are attached to the subject of a sentence. In this case, -이 / -가 markers that sentence subject typically has, disappear.
