Korean Pattern ~나 보다: How to Say "it seems / I guess (based on evidence)"

Verb stem + 나 보다 / Adj stem + (으)ㄴ가 보다. Inference from evidence. Different from ~것 같다 (personal guess).

The Rule

~나 보다 = "it seems / I guess (based on evidence)" Verb stem + 나 보다 / Adj stem + (으)ㄴ가 보다. Inference from evidence. Different from ~것 같다 (personal guess). This is one of the essential Korean grammar patterns. Mastering it unlocks the ability to express "it seems / I guess (based on evidence)" naturally in conversation — something you'll need almost every day.

Why English Speakers Get It Wrong

In English, "it seems / I guess (based on evidence)" is expressed with separate words (auxiliary verbs, modals). In Korean, ~나 보다 is a grammatical ENDING attached to the verb stem. You can't just translate word-by-word. The common mistake: trying to combine Korean words the way English does instead of attaching the pattern to the verb stem. Korean grammar works by stacking endings, not by adding separate helper words.

How It Works

Formation: Verb stem + 나 보다 Verb stem + 나 보다 / Adj stem + (으)ㄴ가 보다. Inference from evidence. Different from ~것 같다 (personal guess). Step by step: 1. Take any verb (e.g., 가다 = to go) 2. Remove 다 to get the stem (가) 3. Add the pattern: 가나 보다 This works with virtually any Korean verb.

Real Examples

• 비가 오나 봐요. (biga ona bwayo.) — "It seems like it's raining. (I see wet umbrellas)" • 맛있나 봐요. 사람이 많네요. (matitna bwayo. sarami manneyo.) — "I guess it's good — there are a lot of people."

Common Mistakes

❌ Trying to translate "it seems / I guess (based on evidence)" word-by-word from English ✅ Use the pattern ~나 보다 attached to the verb stem → Korean expresses "it seems / I guess (based on evidence)" as a single grammatical construction, not separate words. ❌ Forgetting vowel harmony or consonant rules ✅ Check if the verb stem ends in a vowel or consonant — the pattern may change form → Pay attention to the verb stem's final sound when attaching the pattern.

Quick Tip

Practice ~나 보다 with 5 verbs you already know. Write them out: • 가다 (go) → 가나 보다 • 먹다 (eat) → 먹나 보다 Repetition with familiar verbs builds the pattern into muscle memory. Once automatic, you can use it with ANY verb.
