 This usage of 있다 in Korean is an _adjective._ This is hard for a learner to wrap their head around. At this point, this is important to you for one reason.
 
-You learned in [Lesson 1](https://www.howtostudykorean.com/unit1/unit-1-lessons-1-8/unit-1-lesson-1/) that sentences with adjectives cannot act on an object. Thus, you cannot have a word with the particle ~을/를 attached to it if the predicating word in a sentence is an adjective (because ~을/를 indicates an object in a sentence).

-In the [previous lesson](https://www.howtostudykorean.com/unit1/unit-1-lessons-1-8/unit-1-lesson-1/), you learned how to use the particles ~은/는 and ~을/를 to denote the purpose of certain words in a Korean sentence. The particle ~에 is also used to denote certain words in a sentence. Specifically, ~에 denotes a place or time.

-If you haven’t reached [Lesson 17](https://www.howtostudykorean.com/unit1/unit-1-lessons-17-25-2/lesson-17/) (and especially if you haven’t even moved on to [Lesson 3](./03-verbs.md)) you won’t understand what is being described in that lesson. Being able to fully understand the difference between ~이/가 and ~는/은 is important, but not as important (at the moment) as understanding other aspects of Korean grammar. I can’t stress this enough – your understanding of the difference between the two will progress with your Korean development in general.

 The good thing is, even if you make a mistake with the usages of ~이/가 and ~는/은 (either because you are confused or because you haven’t reached the later lessons yet), 99.9% of the time, the listener will be able to understand exactly what you are trying to express. Likewise, if you listen to somebody speaking, you will be able to understand what they are trying to say regardless of if you have learned the more complex usages of ~이/가 and ~는/은. The difference between these two particles is about nuance and does not dramatically change the meaning of the sentence.
 
 Making a mistake between other particles, however, _would_ cause other people to misunderstand you. For example, using ~를/을 instead of ~는/은 would (most likely) make your sentence incomprehensible.
