Today we’ll see some Korean grammar patterns which are used to form sentences to talk about an opinion or conclusion formed on the basis of incomplete information.
Conjecture means to form an opinion or supposition about something on the basis of incomplete information.
V ~(으)/ㄹ거예요
Used to express the speaker's supposition based on a personal experience or something seen or heard that provides a basis for the belief.
This pattern can be used to make future tense sentences. Also, when used for supposition it cannot be used in question form.
For Example:
- 이 옷을 입으면 더울 거예요. - If you wear these clothes, you'll feel hot.
- 티셔츠 입을 거예요. - I'm going to wear a t-shirt.
V ~(으)ㄹ 까요
This grammar is used while asking for someone’s opinion, suggesting to do something together or, used for questions, thoughts or guesses.
For Example:
- 오늘 점심에 뭐 먹을까요? - What shall we eat for lunch today?
- 오늘 밤에 저녁 나가서 먹을까요? - Should we go out for dinner tonight?
A ~아/어/여 보이다
This expression is used to indicate that one feels or guesses something by the appearance of something mentioned in the preceding statement.
It is used in the situation where someone is expressing their feeling on the outward appearance of a person, event or thing. The word 보이다 indicates that something looks/seems like (something).
For Example:
- She looks sad/depressed. 슬퍼 보이다. / 우울해 보이다.
- You look tired. / You looked tired. 피곤해 보이다. / 피곤해 보였다.
V/A ~(으)ㄴ/는/(으)ㄹ 것 같다
It used to express predictions when something seems to be like in a way which might be occurring, may have occurred or will occur in future.
For Example:
- I think it's raining : 비 오는 것 같아요.
- I think it rained today : 오늘 비 온 것 같아요 /오늘 비 왔을 것 같아요.
- I think it will rain today : 오늘 비 올 것 같아요.
A/V-(으)ㄴ/는 모양이다
An expression used to guess that something is in progress or in a certain state, considering another fact or situation.
This grammar pattern is used to infer or guess a situation after observation. About things that you can see or hear.

비가 올 모양이다.
- Seung-gyu has been tired these days, but he seems to be having a hard time at work.
승규가 요즘 계속 피곤해 하던데 일이 힘든 모양이에요.
V/A ~(으)ㄴ/는/(으)ㄹ 줄 알다/모르다

- 이렇게 먹는 줄 몰랐어요. I didn't know you could eat like this.
A/V ~ㄹ/을 리가 없다
An expression used to indicate that the speaker is certain that the content of the preceding statement has an explanation or could possibly be true.
It is used to indicate disbelief or doubt. It has the same meaning as "It's impossible to………"
For Example:
- There's no way he got sick. - 그 사람이 병에 걸렸을 리가 없어요.
- Tests can't be easy. - 시험이 쉬울 리가 없어요.
A/V/N ~(으)ㄹ 걸요
An expression used to indicate that the content of the preceding statement is the speaker's opinion or guess.
It is used as a sentence's final ending that reveals a fact about the future or a supposition of the speaker.
It is equivalent to saying- "probably, I think, I bet".
For Example:
- He'll only go to the movies.

- Jisoo is still going to school.

A/V/N ~듯이
It is a connective ending used when the following statement is almost the same as the preceding statement.
It can also be understood as (second clause) like; as if; as though; as (first clause).
It is often used idiomatically and also when confirming the fact that is known by both the speakers.
For Example:
- Do as your brother does.
네 형이 하듯이 해라.
- Tears pour down like rain.

Usage of 겠
