Korean puts the feeling at the very end of the sentence. 요 makes it polite. 네요 says oh, I've just noticed. 죠 says right?. 잖아요 says you already know this. 거든요 says here's something you don't know. Same sentence, five different social situations.
There is a stage where your Korean is correct and still lands flat. You say 맛있어요 and it sounds like a review. A Korean friend says 맛있네요 and it sounds like delight. Nothing in the dictionary explains the difference, because the difference is not in the words — it is in the syllable stuck on the end.
Start hereBefore anything else: 요 is the boundary between polite 존댓말 and casual 반말. Remove it and you are speaking to a close friend. Keep it and you are safe with anyone.
The friendliest ending in Korean. It marks a discovery happening right now, often with admiration.
Seeks agreement about something you both already believe. It softens a statement into a shared one.
Supplies a reason or piece of information the listener does not have. Very common when explaining or excusing yourself.
Points at shared knowledge. Between friends it is warm and conversational — and aimed at the wrong person it is the most dangerous ending on this page.
Reports something you personally witnessed and found out. It carries the flavour of it turned out that…
Leaves the sentence slightly open, which in Korean is polite rather than indecisive. It is how you disagree, hesitate or set something up gently.
Realisation, mostly to yourself. 구나 is casual; 군요 is its polite twin.

Why these are learned by ear
Every ending above fails a flashcard, because none of them has a fixed English translation. 네요 is “oh” in one sentence and “wow” in the next and nothing at all in the third. They are absorbed by hearing them attached to whole lines, often enough that the feeling arrives before the analysis.
Endings are caught, not studied
Hanguljo's conversation track is built from real dialogues by TOPIK level with native audio and play-along highlighting, and its shadowing mode has you speak each line back with your own microphone until the ending lands where a Korean speaker would put it. Foundation lessons fix the pronunciation underneath, the 7-stage SRS engine returns each grammar point right before you would forget it, and the TOPIK 1–6 lessons carry the vocabulary, grammar and particles that fill these shapes. The on-device OCR looks up anything you meet in the wild.

Frequently asked questions
What does 네요 mean?
Something you have just noticed and are mildly impressed or surprised by. 맛있네요 is a discovery; 맛있어요 is a verdict.
What is the difference between 거든요 and 잖아요?
거든요 gives information the listener does not have; 잖아요 points at information they already do. Mixing them up is what makes 잖아요 sound accusatory.
Is 잖아요 rude?
Not among friends, where it is warm and constant. Toward a stranger, a customer or someone senior it can read as obviously, I told you. Use 거든요 there instead.
What does 더라고요 mean?
It reports something you personally witnessed and discovered: 생각보다 비싸더라고요. Not for second-hand facts.
What happens if you remove 요?
The sentence becomes 반말, casual speech. That one syllable is the whole boundary in the everyday 해요 style.
