Welcome back to Part 2 of the verb 나다—the one verb you must master to sound fluent in Korean. 

Remember, 나다 is about things appearing naturally?
Last time, we talked about senses like smell or sound.
Today, we’re moving to things that pop up on the surface!

Think about things like pimples(뾰루지), acne(여드름), rashes(두드러기/발진), or beards(수염).
These weren’t visible before, but they existed “under the surface” in a different form.

Now, they’ve broken through! This same logic applies to your emotions, and even illnesses. Just like a pimple or a fever was ‘brewing’ inside you before it finally showed up as a symptom.”

Here’s a question students always ask: “When do I HAVE to use the marker ‘-이/-가’?
This is a pro-level tip! Use the markers when:

1. It’s not just a general fact.
2. The sentence is a build-up for what you’re about to say next.

Let’s look at this sentence: “저는 뾰루지가 나요.”

To a Korean ear, this sounds like one of two things: 

First, it can sound like getting pimples is just a regular thing for you—like it’s part of your skin type.

Second, it can sound like you’re comparing yourself to others. In a room full of people talking about skin issues, using “-은/-는” makes it sound like: ‘I don’t know about others, but as for ME, I’m the one getting pimples.’

So, if you just want to say ‘Hey, I got a pimple.’ as a simple fact, you’d just say “여드름 났어요.”

But the moment you add the marker ‘-이/-가,’ you’re creating a build-up.

You’re signaling to the listener: ‘I’m giving you this specific background information because I have something important to say next!

SO, why the case markers? Because of the BUILD-UP! When you connect two sentences, the first part provides the background.

To make that background 100% clear and avoid any misunderstanding, you MUST use the case markers. If you don’t, it’s grammatically incorrect! You’re setting the stage for the main clause (the second part).

Let’s look at these examples and think about the build-up:

1. 화장품을 잘못 써서 뾰루지 났어. (I used the wrong skincare, so a pimple popped up.)
2. 내가 글루텐 알러지가 있어. 그래서 글루텐 먹으면 바로 두드러기 나. (I have a gluten allergy. So if I eat it, I get rashes immediately.)
3. 저는 롤러코스터 못 타요. 겁이 나서 절대 못 타요. (I can’t ride rollercoasters. I get scared, so I absolutely can’t do it.)
4. 일을 너무 많이 해서 몸살 났어요. 저 오늘 쉬어도 돼요? (I worked too much, and now my whole body aches. Can I take the day off today?)

Think about it. The marker is there for a reason! It builds the foundation for your story.
