These pairs cover phrases you’ll hear constantly — in dramas, at work, with friends. Notice the pattern: casual forms tend to be shorter and drop the final syllable that polite forms keep.

How the audio works: tap either phrase in a pair and your device’s built-in Korean voice will say it out loud — no app or download needed.

Notice that last pair especially — sometimes the difference between casual and polite is as small as adding a single 요 syllable to the end. It’s a small change with a real social effect, which is part of why this feels so unfamiliar to English speakers at first.

Recognising the Pattern Is Step One

Once you can spot casual vs polite forms in dialogue, using them correctly yourself becomes a lot more natural. Here’s the step-by-step system we recommend for building that skill.
