확신하다 vs 의심하다 – To Be Sure vs To Doubt in Korean

Learning Korean can be a fascinating journey, especially when you delve into the nuances of verbs that convey emotions and states of mind. Two such verbs are 확신하다 (to be sure) and 의심하다 (to doubt). Understanding the differences and applications of these verbs can significantly enhance your ability to express certainty and skepticism in Korean.

확신하다 is a verb that means “to be sure” or “to be certain.” This verb is used when you are confident about a fact, an event, or a situation. For example, if you are certain that it will rain tomorrow, you might say, “내일 비가 올 것을 확신해요,” which translates to “I am sure that it will rain tomorrow.”

On the other hand, 의심하다 means “to doubt” or “to suspect.” This verb is used when you have reservations or uncertainties about something. For instance, if you doubt someone’s story, you could say, “그 이야기를 의심해요,” which means “I doubt that story.”

To better understand how to use these verbs, let’s explore their usage in different contexts.

First, let’s look at 확신하다 in more detail:

1. **Expressing Certainty**:
When you are absolutely certain about something, 확신하다 is the verb to use. For example:

Next, let’s delve into the usage of 의심하다:
