You do not need to speak fluent Korean to start building a life here. But a small amount of useful Korean changes everyday interactions immediately.
My advice is to learn phrases connected to situations you actually encounter. A sentence you use three times this week will stay with you much longer than a vocabulary list you never need.
Start with the phrases that make interactions smoother
안녕하세요 (annyeonghaseyo) — Hello.
감사합니다 (gamsahamnida) — Thank you.
죄송합니다 (joesonghamnida) — I’m sorry / excuse me.
괜찮아요 (gwaenchanayo) — It’s okay.
These are simple, but they do a lot of work. Using a polite greeting before launching into English or a translation app makes an interaction feel much warmer.
At shops and restaurants
이거 주세요 (igeo juseyo) — Please give me this.
얼마예요? (eolmayeyo?) — How much is it?
카드 돼요? (kadeu dwaeyo?) — Can I pay by card?
포장해 주세요 (pojanghae juseyo) — Please pack it to go.
여기서 먹을게요 (yeogiseo meogeulgeyo) — I’ll eat here.
When you do not understand
잘 모르겠어요 (jal moreugesseoyo) — I’m not sure / I don’t understand well.
다시 말씀해 주세요 (dasi malsseumhae juseyo) — Please say that again.
천천히 말씀해 주세요 (cheoncheonhi malsseumhae juseyo) — Please speak slowly.
한국어를 잘 못해요 (hangugeoreul jal mothaeyo) — I don’t speak Korean well.
You do not need to apologize repeatedly for your Korean. State what you need, use your translation app if necessary and keep going.
Getting around
여기 어디예요? (yeogi eodiyeyo?) — Where is this?
화장실 어디예요? (hwajangsil eodiyeyo?) — Where is the restroom?
여기 세워 주세요 (yeogi sewo juseyo) — Please stop here.
For actual navigation, use Naver Map or KakaoMap rather than relying only on spoken directions.
At work
확인해 보겠습니다 (hwaginhae bogetseumnida) — I’ll check.
다시 확인해 주세요 (dasi hwaginhae juseyo) — Please check again.
언제까지 필요하세요? (eonjekkaji piryo haseyo?) — When do you need it by?
문제가 있습니다 (munjega itseumnida) — There is a problem.
Workplace Korean depends heavily on your industry, so build your own vocabulary list from words you hear repeatedly. For context around communication and hierarchy, see the Korean workplace culture guide.
Learn Hangul early
Romanization is useful for getting started, but do not depend on it for long. Hangul is logical enough to learn at a basic reading level surprisingly quickly. Once you can sound out signs and names, the country becomes easier to navigate.
Use Korean before you feel ready
Waiting until your grammar is perfect is a good way to never speak. Use one phrase today, another tomorrow, and let real life provide the repetition.
Most people care far more that you are trying to communicate respectfully than whether every ending is perfect.
