Definition of ‘Because’ in Korean
In Korean, expressing “because” involves using various grammatical structures that connect two clauses, indicating a cause-and-effect relationship. These structures function as conjunctions or sentence connectors, explaining the reason or cause behind a particular action or state.
The choice of which structure to use often depends on the nuance you want to convey, the formality of the situation, and the relationship between the speaker and the listener. Unlike English, Korean grammar often places the cause before the effect in a sentence.
The primary functions of “because” in Korean are to provide reasons, justifications, or explanations for events, actions, or states. It allows speakers to create logical connections between ideas, making their communication more clear and persuasive.
These structures are essential for expressing opinions, giving advice, and describing events in a coherent manner. Mastering these connectors will significantly improve your ability to construct complex and meaningful sentences in Korean.
Structural Breakdown
The structure for expressing “because” in Korean typically involves attaching a specific suffix or phrase to the verb stem or adjective stem of the clause that represents the cause. This modified clause is then followed by the clause that represents the effect.
Understanding the basic structure is essential for correctly using these expressions.
The general structure can be represented as follows:
[Cause Clause + Connector] + [Effect Clause]
For example, using the connector -(아/어)서:
비가 오다 (bi ga oda – it rains) + -(아/어)서 → 비가 와서 (bi ga waseo – because it rains)
비가 와서 집에 있어요 (bi ga waseo jibe isseoyo – Because it’s raining, I’m at home.)
The specific connector used will influence the conjugation rules and the overall nuance of the sentence. It’s important to pay attention to the verb or adjective stem ending to conjugate correctly.
The following sections will delve into the specific structures and their conjugation rules in detail.
Types and Categories of ‘Because’ in Korean
There are several ways to express “because” in Korean, each with its own nuances and usage contexts. The most common connectors include -(아/어)서, -(으)니까, 기 때문에, 때문에, and -(는/은)데.
Each of these will be explained in detail below.
-(아/어)서
-(아/어)서 is one of the most common and versatile ways to express “because” in Korean. It is attached to the verb or adjective stem and indicates a sequence of events or a cause-and-effect relationship.
The choice between -아서 and -어서 depends on the last vowel of the verb/adjective stem.
- If the last vowel is ㅏ or ㅗ, use -아서.
- If the last vowel is anything other than ㅏ or ㅗ, use -어서.
- If the verb stem ends in 하다, it changes to 해서.
-(으)니까
-(으)니까 is another common way to say “because” in Korean. It implies a reason, justification, or discovery of a new fact that leads to a certain action or decision.
The choice between -으니까 and -니까 depends on whether the verb/adjective stem ends in a consonant or a vowel.
- If the verb/adjective stem ends in a consonant, use -으니까.
- If the verb/adjective stem ends in a vowel, use -니까.
- Exception: 있다 becomes 있으니까.
기 때문에
기 때문에 is a more formal and emphatic way of saying “because” in Korean. It is attached to the verb or adjective stem and indicates a strong reason or justification.
It’s often used in written Korean or formal speaking situations.
To use 기 때문에, simply attach it to the verb/adjective stem in its dictionary form.
때문에
때문에 is a noun meaning “because of” or “due to.” It is used with nouns to indicate that the noun is the reason for something. It is similar to “because of” in English.
To use 때문에, attach it directly to the noun.
-(는/은)데
-(는/은)데 has multiple functions, including expressing “because” or providing background information. It’s often used when the second clause is unexpected or contrasts with the first clause.
The choice between -는데 and -은데 depends on whether the verb/adjective stem ends in a consonant or a vowel.
- For verbs, use -는데.
- For adjectives ending in a vowel, use -ㄴ/는데.
- For adjectives ending in a consonant, use -은데.
- 있다/없다 become 있는데/없는데.
- 이다 becomes -ㄴ/은데 depending on the preceding noun ending.

Usage Rules
Understanding the specific usage rules for each “because” connector is crucial for accurate and effective communication. Here’s a breakdown of the key rules:
- -(아/어)서: Primarily used to indicate a sequence of events or a direct cause-and-effect relationship. It’s important to ensure that the events are logically connected. It cannot be used to express intention or command in the second clause.
- -(으)니까: Used to express a reason, justification, or discovery of a new fact that leads to a certain action or decision. The second clause often involves a suggestion, command, or intention.
- 기 때문에: A more formal and emphatic way of expressing “because.” It indicates a strong reason or justification. It is generally used in formal settings or written Korean.
- 때문에: Used with nouns to indicate that the noun is the reason for something. It is similar to “because of” in English.

Learners often make mistakes when using “because” in Korean. Here are some common errors and how to avoid them:
| Incorrect | Correct | Explanation |
|---|---|---|
| 비 때문에 집에 갔어요. | 비가 와서 집에 갔어요. | 때문에 is used with nouns, not verbs. Use -(아/어)서 with verbs. |

| 바쁘니까 지금 전화했어요. | 바빠서 지금 전화했어요. | -(으)니까 implies a suggestion or command in the second clause, which doesn’t fit the past tense action. -(아/어)서 is more appropriate. |
