The Crab and Its Mother

똑바로 앞으로 걸어야지.

You should walk straight forward.

Real Pattern

This is a classic way to tell someone the 'right' or 'proper' way to do something. The -어야지 ending carries a sense of mild chiding, advice, or stating an obvious rule, like a parent talking to a child or someone reminding themselves of what they need to do.

Pattern Application

글씨를 똑바로 써야지. 그래야 다른 사람이 읽을 수 있어. — You should write straight. That way other people can read it.

늦었어! 이제 그만 자고 일어나야지. — It's late! You should stop sleeping and get up now.

음식은 남기면 안 돼. 골고루 다 먹어야지. — You shouldn't leave food behind. You're supposed to eat a balanced meal.

Tip

While -(아/어)야지 can be used to talk to yourself ("I should get going..."), when said to others, it can sound a bit like nagging or talking down to them. It's most natural in close relationships, like family.

똑바로 앞으로 걸어야지

정말로 몰라서 묻는 거였어요.

I was asking because I truly didn't know.

Real Pattern

Use this phrase to clarify that your question is genuine and not a trick, a test, or a challenge. It emphasizes sincerity and pure curiosity. In conversation, you'd typically say 정말로 몰라서 묻는 거예요 (present tense).

Pattern Application

이거 어떻게 사용하는 거예요? 정말로 몰라서 묻는 거예요. — How do you use this? I'm asking because I really don't know.

A: 왜 그런 당연한 걸 물어봐? B: 비꼬는 거 아니야. 진짜 몰라서 묻는 거야. — A: Why are you asking something so obvious? B: I'm not being sarcastic. I'm asking because I genuinely don't know.

Tip

This phrase is useful for learners who worry their questions might sound too simple or obvious. It's a polite way to signal, "Please don't judge my question; I'm here to learn."

정말로 몰라서 묻는 거였어요

그거야 쉽지.

Oh, that's easy, of course.

Real Pattern

This phrase expresses confidence, sometimes overconfidence, about a task. The -(이)야 particle adds emphasis, like saying "As for that, it's easy." It can sound confident and capable, or a bit boastful, depending on the context and tone.

Pattern Application

A: 이 수학 문제 풀 수 있어? B: 그거야 쉽지. 5분이면 돼. — A: Can you solve this math problem? B: Oh, that's easy. It'll only take 5 minutes.

컴퓨터 고치는 거? 그거야 쉽지. 내가 전문가잖아. — Fixing the computer? That's a piece of cake. I'm the expert, after all.

Tip

Be careful with your tone. Said humbly, it's reassuring. Said with a smirk, it can come across as arrogant, just like the mother crab before she tried to walk straight.

그거야 쉽지

어찌 된 일일까요?

What could have happened? / How did this come to be?

Real Pattern

This is a classic phrase used to express surprise, confusion, or disbelief when faced with an unexpected outcome. It's often used in storytelling to create suspense, but you can also use it in daily life when something goes wrong unexpectedly.

Pattern Application

어제까지 잘 되던 컴퓨터가 안 켜져요. 어찌 된 일일까요? — The computer was working fine until yesterday, but now it won't turn on. What could have happened?

분명히 여기에 지갑을 뒀는데 없어졌어요. 어찌 된 일이죠? — I'm sure I put my wallet here, but it's gone. How can this be?

Tip

In conversation, 어찌 된 일이죠? or 이게 어찌 된 일이야? (more casual) are more common than the storybook-like -일까요? ending.

어찌 된 일일까요?

얼굴이 빨개졌지요.

Her face turned red.

Real Pattern

This is a very common idiom for being embarrassed, ashamed, or shy. Just like in English, a red face (빨간 얼굴) is directly linked to the feeling of embarrassment. You can use it to describe yourself or someone else.

Pattern Application

많은 사람들 앞에서 실수해서 얼굴이 빨개졌어요. — I made a mistake in front of a lot of people, so my face turned red.

그 사람이 제 칭찬을 하자 부끄러워서 얼굴이 빨개졌어요. — When that person complimented me, I got shy and my face flushed.

Tip

This phrase specifically points to embarrassment or shyness. For a face that's red from anger, you would more likely say 얼굴이 붉으락푸르락 해졌다.
