‘-모양이다’ is used when your guess comes from something you can see, hear, or observe. It is not a random assumption but an evidence-based interpretation.

6. Common Mistakes and Tips for Using -(으)ㄴ/는 모양이다
⚠️ Mistake 1 — Using the Wrong Tense Form
Incorrect: 사람들이 우산을 쓰는 걸 보니 비가 온 모양이에요. ❌
Correct: 사람들이 우산을 쓰는 걸 보니 비가 오는 모양이에요. ✅
💡 Tip: In present inference, for action verbs use -는 모양이다, not the past form -(으)ㄴ 모양이다
⚠️ Mistake 2: Using 모양이다 for yourself (“I”)
Incorrect: 제가 많이 피곤한 모양이에요. ❌
Correct: 제가 많이 피곤한 것 같아요. ✅
💡 Tip: 모양이다 is used to infer based on outside evidence or observation. Since you don’t need to infer your own state, use 것 같다 or other forms instead.
⚠️ Mistake 3: Confusing 모양이다 with 것 같다 in nuance
Incorrect: 사람들이 우산을 쓰는 걸 보니 비가 오는 것 같아요. ❌ (less precise inference)
Correct: 사람들이 우산을 쓰는 걸 보니 비가 오는 모양이에요. ✅
💡 Tip: Both 모양이다 and 것 같다 mean “it seems,” but 모양이다 is stronger and shows inference based on clear evidence. Use it when your guess comes from what you see or hear.
