Realizing Something: -군요 & -는군요
Learn Realizing Something: -군요 & -는군요 with form rules, natural examples, common mistakes, romanization, and six practice questions with answers.
Introduction / Review
Use -군요 or -는군요 to react to a fact you have just realized. It often sounds reflective: “Oh, I see ….” The choice depends on the predicate type, not simply whether its stem has a final consonant.
N = noun; V = action verb; A = descriptive verb. Romanization is a reading aid.
Today’s Grammar / Explanation
- Present adjectives: A-군요, without 으: 좋다 → 좋군요; 작다 → 작군요. Present action verbs: V-는군요: 먹다 → 먹는군요; 일하다 → 일하는군요.
- A final ㄹ in an action verb drops before 는: 살다 → 사는군요. Adjectival ㄹ stays before 군요: 멀다 → 멀군요.
- Nouns: 학생이군요; 의사군요/의사이군요. Past predicates take 았/었군요: 갔군요, 바빴군요. 있다/없다 use 있군요/없군요.

yeogieseo ilhaneungunyo

-(으)ㄴ/는데요
저는 일본에서 왔는데요.-(으)ㄴ/는데요 gives background and waits for a reaction. -군요 is often that reaction.
Look ahead: Lesson 63 →| Pattern | Attaches to | Example |
|---|---|---|
| -군요 | adjectives, 이다, past tense | 비싸군요, 학생이군요, 왔군요 |
| -는군요 | action verbs (present) | 잘 먹는군요 |
| -네요 | anything (noticing) | 비싸네요, 잘 먹네요 |
| -구나 | casual form | 아, 그렇구나 |
Common mistakes
Adjectives take -군요 without 으: 좋다 → 좋군요. Do not write 좋으군요 for this pattern. -네요 and -군요 can overlap; avoid a rigid claim that one always requires seeing and the other always requires hearing.
Action verbs in the present take -는군요.
Adjectives take -군요.
After a noun ending in a consonant, keep 이: 반장이군요.
For something already completed, use the past: 도착했군요.
