The particle -을/를 is one of the most basic particles in Korean grammar a Korean language learner has to master. If you do not know how to use it and what it signifies, understanding even basic Korean sentences becomes almost impossible. So let’s make sure you truly understand this particle
The particle -을/를 is known as the object particle because it indicates the direct object in a Korean. That is why many verbs will require you to use this particle. However, in spoken Korean, people tend to omit the particle. Typically, the context is enough to make clear what the direct object in a sentence is. But, when it isn’t you have to use it.
가: 뭐 하고 싶에요?
나: 수영하러 바다에 가고 싶어요.
A: What do you want to do?
B: I want to go to the beach to swim.
How To Use
The particle -을/를, like the other two basic particles -은/는 and -이/가, follows the ‘batchim/no batchim’ rule in Korean. This means that you use -을 when a noun ends in a batchim (ends in a consonant). But, when it ends in no batchim (a vowel), you use -를. After that, there is little else to do.
