🌈 The Big Picture

• Is it based on visible signs? Use something like -(으)ㄴ/는 모양이다. 👀

• Is it a casual inference from evidence? Use -나 보다. 💬

• Is it reflective, formal, or report-like? Use -(으)ㄴ/는가 보다. 🧾

• Is it soft, impressionistic, or literary? Use -(으)ㄴ/는 듯하다. 🌫️

• Is it logically plausible or reasonable? Use -(으)ㄹ 법하다. ⚖️

• Is it broad and conversational? Use -(으)ㄹ 것 같다. 🧠

🎨 The Core Speculation Family

1. -나 보다 / -(으)ㄴ가 보다 — conversational inference 💬

• 회의가 아직 안 끝났나 봐요. — I guess the meeting has not ended yet. 🚪

• 자료가 부족한가 봐요. — I guess the materials are insufficient. 📄

2. -(으)ㄴ/는가 보다 — reflective or analytical inference 🧾

• 자료를 보면 수요가 줄어드는가 봅니다. — Looking at the data, demand appears to be decreasing. 📉

• 정황상 내부 논의가 끝났는가 봅니다. — Judging from the circumstances, it appears the internal discussion has ended. 🗂️

3. -(으)ㄴ/는 모양이다 — appearance or visible signs 👀

• 표정이 어두운 걸 보니 일이 잘 안 된 모양이에요. — Seeing the dark expression, it looks like things did not go well. 😟

4. -(으)ㄴ/는 듯하다 — soft impression, literary seeming 🌫️

• 분위기가 조금 달라진 듯해요. — The atmosphere seems to have changed a little. 🕯️

• 그 설명은 핵심을 비켜 간 듯합니다. — That explanation seems to have missed the main point. 🎯

5. -(으)ㄹ 법하다 — reasonable likelihood ⚖️

🛠️ How They Work in a Sentence

Same clue, different stance

• 문이 닫혀 있어요. 회의가 끝났나 봐요.
The door is closed. I guess the meeting has ended. 🚪
문 = door; 닫혀 있다 = to be closed; 회의 = meeting.

• 문이 닫혀 있는 걸 보니 회의가 끝난 모양이에요.
Seeing that the door is closed, it looks like the meeting has ended. 👀
This makes the visible sign more explicit.

• 정황상 회의가 끝났는가 봅니다.
Judging from the circumstances, it appears the meeting has ended. 🧾
This sounds more report-like and analytical.

Same result, different logic

• 설명이 짧아서 사람들이 오해할 법해요.
The explanation is short, so people could reasonably misunderstand. 🧩
설명 = explanation; 짧다 = to be short; 오해하다 = to misunderstand.

• 사람들이 이미 오해한 듯해요.
People seem to have already misunderstood. 🌫️
This sounds softer and focuses on impression.

• 사람들이 오해한 것 같아요.
I think people misunderstood. 💬
This is broad and conversational.

• ❌ 사실 법해요 → ✅ 사실일 법해요 (noun + 일 법하다).

• ❌ Using 법하다 for pure certainty → ✅ use 틀림없다 when there is no doubt.

• ❌ Using 모양이다 without any sign or appearance → ✅ use it when the situation “looks like” something.
