설명하다

The Korean verb 설명하다 (seol-myeong-ha-da) is a cornerstone of communication, functioning as the primary way to express the act of explaining, clarifying, or detailing information. At its core, it combines the concept of speaking with the concept of clarity. When you use this word, you are not just talking; you are actively working to ensure that your listener understands a specific concept, reason, or process. It is used in almost every facet of Korean life, from the classroom where a teacher explains a difficult math problem to a business meeting where a manager explains a new strategy, and even in personal relationships when someone needs to explain their feelings or actions to avoid a misunderstanding. The word carries a sense of intentionality and logic, suggesting a structured delivery of information rather than a casual chat.

Core Concept

The act of making a complex or unknown subject clear to another person through verbal or written means.

Etymological Nuance

Derived from Hanja, '설' (說) means to speak or persuade, and '명' (明) means bright or clear. Literally, it is 'speaking to make things bright.'

In everyday usage, you will encounter this word frequently when someone is seeking help. For example, if you are lost in Seoul and ask for directions, the person helping you might say, '제가 길을 설명해 드릴게요' (I will explain the way to you). Here, the word bridges the gap between the unknown (the route) and the known (the destination). It is also the standard word used in academic contexts. Textbooks are filled with '설명' (the noun form), and students are often asked to '설명해 보세요' (please try to explain). This highlights its role in the transfer of knowledge. Furthermore, in legal or formal contexts, it refers to the official presentation of facts or evidence.

The versatility of '설명하다' is also seen in how it handles different levels of complexity. You can explain something simple, like a schedule, or something incredibly abstract, like a philosophical theory. The word remains the same, but the context dictates the depth. In social media or modern digital culture, you might see '설명' used in '설명충' (seol-myeong-chung), a slang term for someone who over-explains things that are already obvious, often in an annoying way. This shows how the word has permeated even the most casual and humorous parts of the language. Understanding this word is essential because it is the gateway to deeper conversations; without being able to explain, one is limited to simple statements of fact.

Finally, it is important to distinguish '설명하다' from '말하다' (to speak/say). While '말하다' is the general act of producing speech, '설명하다' is the specific act of clarifying. If you say '그는 사실을 말했다,' he simply stated the fact. If you say '그는 사실을 설명했다,' he provided the context, the reasons, and the details surrounding that fact. This distinction is vital for B1 learners who are moving beyond basic sentences into more descriptive and analytical Korean. By mastering this word, you gain the ability to participate in discussions, defend your opinions, and help others understand your perspective, making it one of the most powerful verbs in your Korean vocabulary arsenal.

Using 설명하다 correctly involves understanding its relationship with various particles and sentence structures. As a transitive verb, it typically takes an object marked by the particle ~을/를. The person receiving the explanation is usually marked by ~에게 (to) or ~한테 (to, more casual). For example, '나는 친구에게 규칙을 설명했다' (I explained the rules to my friend). This structure is the foundation for most sentences involving this verb. However, the complexity increases when you add adverbs to describe how the explanation is being given. Common adverbs include 자세히 (in detail), 친절하게 (kindly), 간단하게 (briefly), and 정확하게 (accurately).

Common Particle Patterns

[Subject]이/가 + [Recipient]에게 + [Topic]을/를 + 설명하다.

Honorific Usage

When a superior is explaining, use '설명하시다'. When asking a superior to explain, use '설명해 주시겠어요?'.

In more advanced sentences, '설명하다' often interacts with clause connectors. For instance, when explaining why something happened, you might use the structure '[Reason]~에 대해 설명하다' (explain about [Reason]). Or, you might use a quoted clause: '그는 왜 늦었는지 설명했다' (He explained why he was late). Notice how the indirect question '왜 늦었는지' (why he was late) acts as the object of the verb. This is a very common pattern in B1 and B2 level Korean. It allows the speaker to move beyond simple nouns and explain entire situations or sequences of events. Another important variation is the use of the causative or passive-like structures, though '설명되다' (to be explained) is the most common passive form, used when the focus is on the information itself rather than the person giving it.

One must also be aware of the register. In a formal presentation, you might say '지금부터 이번 프로젝트의 목적을 설명하겠습니다' (From now, I will explain the purpose of this project). The use of the future-intention marker ~겠습니다 adds a professional tone. In contrast, in a casual setting with friends, you might say '그게 무슨 뜻인지 좀 설명해 봐' (Try explaining what that means). Here, the '아/어 봐' (try doing) construction makes the request more informal and direct. The verb can also be combined with '수 있다' (can) to express ability: '나는 이 현상을 과학적으로 설명할 수 있다' (I can explain this phenomenon scientifically). This demonstrates the speaker's competence or knowledge.

Lastly, consider the negative forms. '설명하지 않다' is the standard long negation, while '설명 못 하다' implies an inability to explain despite wanting to. For example, '너무 복잡해서 설명 못 하겠어요' (It's so complex I can't explain it). This nuance is crucial for expressing frustration or limitations in communication. As you practice, try to build sentences that incorporate these different elements—particles, adverbs, connectors, and honorifics—to fully grasp the functional range of '설명하다'. It is not just a word to memorize, but a tool to build complex, meaningful interactions in Korean.

You will hear 설명하다 in a wide variety of real-world scenarios, making it one of the most 'audible' verbs in Korean society. One of the most common places is in the **education system**. From elementary school to university lectures, the word is ubiquitous. Teachers use it to introduce new topics, and students use it during presentations. If you visit a Korean university, you'll hear professors saying, '이 이론에 대해 다시 한번 설명하겠습니다' (I will explain this theory once more). It sets the tone for a learning environment where information is being transferred systematically. Even in private academies (hagwons), the quality of a teacher is often judged by how well they '설명하다'.

In the Workplace

Used during briefings, product launches, and training sessions to ensure all employees are on the same page.

In Customer Service

Staff at banks, airports, or tech support centers will use it to guide customers through processes or terms and conditions.

Another major arena for this word is **broadcast media and news**. News anchors often say, '기자가 자세한 상황을 설명해 드립니다' (The reporter will explain the detailed situation). Here, it implies a professional relaying of facts. In documentaries, the narrator '설명한다' the history or science behind the visuals. If you watch Korean variety shows, you might see a game where one person has to explain a word without saying it, and the others have to guess. In this context, '설명하다' becomes part of the entertainment, often leading to funny situations when the explanation is poor or the guesser is confused. This shows the word's transition from formal to playful contexts.

In **daily social life**, the word is used to resolve conflicts or clarify intentions. If a friend is upset, you might say, '오해하지 마, 내가 설명할게' (Don't misunderstand, I'll explain). In this sense, '설명하다' acts as a tool for emotional clarity and social harmony. You'll also hear it at **tourist attractions**. Audio guides and human guides are there specifically to '설명하다' the significance of what you are seeing. If you buy a new electronic device in Korea, the clerk might offer a '제품 설명' (product explanation) to show you how it works. This is a standard part of the high-quality customer service culture in Korea, where ensuring the customer understands the product is paramount.

Finally, you'll hear it in **legal and administrative settings**. When you go to a government office (dong-samuso) to apply for a visa or a permit, the official will '설명하다' the required documents. In courtrooms, lawyers '설명하다' their arguments. The word carries the weight of authority in these settings. Because it is so common, hearing '설명하다' should trigger a mental 'listening mode' in you—it signals that important, clarifying information is about to follow. Whether it's a YouTube tutorial starting with '오늘은 ~에 대해 설명해 보겠습니다' or a friend saying '말하자면 긴데, 설명해 줄게,' this word is the universal signal for the beginning of an informative exchange.

While 설명하다 is a straightforward verb, English speakers often make several common errors when integrating it into their Korean. The most frequent mistake is **confusing it with '말하다' (to speak/say)**. In English, we often use 'tell' or 'say' in places where Korean requires 'explain'. For example, if you want to say 'Tell me why you did that,' a literal translation might lead you to '왜 그랬는지 말해줘.' While not wrong, if you want a detailed reason, '왜 그랬는지 설명해줘' is much more natural. '말하다' is about the act of utterance, while '설명하다' is about the content and clarity of the message. Using '말하다' when you mean 'explain' can make your Korean sound overly simplistic or vague.

Particle Errors

Using '~를' for the person instead of '~에게'. Incorrect: '친구를 설명했다'. Correct: '친구에게 설명했다'.

Confusing with '이야기하다'

'이야기하다' is for storytelling or chatting; '설명하다' is for logical clarification. Don't use '설명하다' for casual gossip.

Another common pitfall is the **misuse of the causative form**. Learners sometimes try to say 'make someone explain' by using awkward constructions. The correct way to say 'I made him explain' would be '그에게 설명하게 했다'. However, a more common mistake is using '설명시키다' (to order an explanation) in the wrong context. '설명시키다' is quite forceful, like a teacher making a student explain a mistake. If you just asked someone to explain, stick to '설명해 달라고 했다'. Additionally, learners often forget to use the **honorific '주시다'** when asking for an explanation. Saying '설명해!' to a stranger or a teacher is very rude. It should always be '설명해 주세요' or '설명해 주시겠어요?' to maintain proper social etiquette.

The **omission of the object** can also lead to confusion. In English, we can say 'Can you explain?' and the object is implied. In Korean, while you can sometimes omit the object, it's often better to include it or use a demonstrative like '그것을' (that) or '이것을' (this) to be clear. '설명해 줄래?' sounds a bit abrupt compared to '그 부분을 좀 더 설명해 줄래?' (Can you explain that part a bit more?). Furthermore, watch out for the **passive form '설명되다'**. Learners often use '설명하다' when the subject is an inanimate object, like 'The book explains...'. In Korean, books don't 'explain' (active); rather, 'the book contains an explanation' or 'it is explained in the book' (이 책에 설명되어 있다). Using '책이 설명한다' sounds like the book has a mouth and is talking.

Finally, be careful with **over-explaining**. As mentioned earlier, the term '설명충' exists for a reason. In Korean culture, sometimes things are left unsaid to maintain 'nunchi' (social intuition). If you '설명하다' every tiny detail of why you were two minutes late, it might actually come across as making excuses rather than being helpful. Learning when *not* to explain is just as important as learning how to use the verb itself. Focus on being concise and only providing the '설명' that is actually needed for the listener's understanding. By avoiding these common grammatical and social mistakes, your use of '설명하다' will sound much more like a native speaker's.

To truly enrich your Korean vocabulary, you need to know the alternatives to 설명하다. While it is the most general term, other words provide more specific nuances depending on the context. For instance, **해설하다 (hae-seol-ha-da)** is often used for 'commentary' or 'interpretation'. You'll hear this in sports (sports commentary) or when an expert is interpreting a difficult text or a work of art. While '설명' is about making it clear, '해설' is about providing a deeper interpretation or analysis. If you are explaining a soccer match, you are '해설'ing it.

설명하다 vs. 해설하다

'설명' is general clarification; '해설' is expert commentary or interpretation (e.g., a movie critic).

설명하다 vs. 묘사하다

'설명' is about logic and reasons; '묘사' (myo-sa) is about visual or sensory description (e.g., describing a sunset).

설명하다 vs. 안내하다

'안내' (an-nae) is 'to guide' or 'to inform' about a place or a process (e.g., a tour guide or information desk).

Another useful alternative is **풀이하다 (pul-i-ha-da)**. This literally means 'to unwrap' or 'to solve'. It is most commonly used in the context of solving problems, especially math problems or riddles. When you '풀이' a problem, you are explaining the step-by-step solution. It feels more mechanical and process-oriented than '설명'. Then there is **강의하다 (gang-ui-ha-da)**, which means 'to lecture'. This is a specific type of explanation done by a teacher or professor in a formal educational setting. You wouldn't '강의' your friend about why you're late, but a professor '강의's about the history of the Joseon Dynasty.

For more formal or academic contexts, you might encounter **상술하다 (sang-sul-ha-da)**, which means 'to describe in detail' or 'to elaborate'. This is rarely used in speech but is common in academic papers or formal reports. Similarly, **역설하다 (yeok-seol-ha-da)** means 'to emphasize' or 'to argue strongly'. It's a type of explanation that carries a strong persuasive intent. If a politician is explaining why a new law is necessary, they might be '역설'ing its importance. On the more casual side, **일러주다 (il-leo-ju-da)** is a native Korean word that means 'to tell' or 'to inform' someone about something they should know. It has a slightly more personal, helpful tone, like an older sibling giving advice.

Understanding these synonyms allows you to choose the exact 'flavor' of explanation you want to convey. Are you solving a problem (풀이)? Are you interpreting art (해설)? Are you guiding a tourist (안내)? Or are you simply making a situation clear (설명)? By diversifying your vocabulary, you move from being a basic learner to a sophisticated communicator. Practice replacing '설명하다' with these alternatives in specific contexts to see how it changes the nuance of your sentences. This level of precision is what distinguishes a B1 learner from a B2 or C1 speaker.
