How to use 틀림없다?

"틀림없다" means "there is no doubt" or "it must be true." It is used to express strong certainty about a fact or situation. You typically use it after a noun or verb stem, often in statements where you are confident about something.

How is 싶다 used to express doubt?

"싶다" is often used to express personal thoughts or assumptions, similar to "I think" or "it seems like" in English. While it can indicate some level of certainty, it is generally less strong than "틀림없다" and is often used when making subjective judgments.

Should I use 리가 없다 or 틀림없다?

"리가 없다" is used to strongly deny the possibility of something happening, similar to saying "there's no way" or "it can't be" in English. On the other hand, "틀림없다" expresses strong certainty that something is true. They are opposites in function—one affirms certainty, while the other denies possibility.

Is 싶다 both formal and informal?

Yes, "싶다" can be used in both formal and informal contexts. However, in formal writing or speech, you might prefer "생각된다" or "것 같다" for a more polished tone.

What to use besides 틀림없다 and 리가 없다?

Yes, other expressions like "확실하다" (to be certain), "분명하다" (to be clear/obvious), and "말도 안 된다" (that makes no sense) can also be used to express certainty and doubt, depending on the context.
