Native Nuance & Mistakes
A common mistake is stating a guess as a fact. -(으)ㄹ 것 같다 is crucial for sounding natural and polite when you are not completely sure.
Guess vs. Fact
Context: When you see someone you don't know, guessing their job with "저 사람은 의사예요" (That person is a doctor) is a strong statement of fact. If you're wrong, it's awkward. Using "저 사람은 의사인 것 같아요" (I think that person is a doctor) is a soft guess, which is much more natural and safer.
Example: (Seeing someone in a white coat at a hospital) -> "의사인 것 같아요." is more natural than "의사예요."
Softening Your Opinion
Context: Even when you have a strong opinion, using -(으)ㄹ 것 같다 can make you sound less assertive and more collaborative. For example, when suggesting a plan, "이 방법이 좋을 것 같아요" (I think this method will be good) sounds more open to discussion than "이 방법이 좋아요" (This method is good).
Do: 저 사람은 학생일 것 같아요 (O) / Don't: 저 사람은 학생이에요 (X)
