을/를 통해

The Korean phrase 을/를 통해 (eul/reul tonghae) is a versatile and essential grammatical construction used to indicate the medium, channel, or process by which an action occurs or a result is achieved. In English, it most closely translates to 'through,' 'via,' 'by means of,' or 'by way of.' It is derived from the verb 통하다 (tonghada), which means 'to pass through' or 'to flow.' When you use 을/를 통해, you are identifying a specific intermediary—be it a person, a tool, a platform, or an abstract experience—that allowed something to happen. It is ubiquitous in both spoken and written Korean, appearing in everything from casual conversations about how you met a friend to academic papers discussing data analysis. Understanding this phrase is a major step in moving from simple subject-verb-object sentences to more complex, descriptive language that explains how things connect in the world.

Literal Path

It can describe physically moving through a space, like air coming through a window.

Intermediary Person

It is often used when a third party facilitates a meeting or a message delivery.

Method or Tool

It describes using technology or specific methods, such as 'through the internet' or 'through research.'

The phrase is composed of the object marker (을 or 를) followed by '통해,' which is the connective form of '통하다.' Because it functions as a postpositional phrase, it always follows a noun. If the noun ends in a consonant, use '을 통해'; if it ends in a vowel, use '를 통해.' In more formal writing or speech, you might see it as 을/를 통하여, which is the full, non-contracted version. This formal variant is common in news broadcasts, textbooks, and business reports. The usage of 을/를 통해 is a hallmark of natural Korean; while beginners might rely heavily on the particle -로/으로 (by/with), intermediate and advanced speakers use 을/를 통해 to specify the 'channel' of information or experience more precisely. For example, while '컴퓨터로' means 'using a computer,' '컴퓨터를 통해' implies the computer was the gateway or medium for the entire process.

In social contexts, 을/를 통해 is frequently used to avoid sounding too direct or to give credit where it is due. Instead of saying 'I found this job,' saying 'I found this job through a professor' (교수님을 통해 이 직장을 구했습니다) provides helpful context and shows respect for the network involved. It is also the standard way to talk about learning from experiences. Phrases like '실패를 통해 배우다' (to learn through failure) or '여행을 통해 깨닫다' (to realize through travel) are common idioms of personal growth. Because it focuses on the process, it adds a layer of depth to your sentences, showing that you understand the relationship between cause, medium, and effect. Whether you are browsing the web, talking to colleagues, or reading a novel, you will encounter this phrase constantly, making it a cornerstone of functional Korean literacy.

News Context

'정부는 성명을 통해 입장을 밝혔습니다' (The government clarified its position through a statement).

Daily Life

'앱을 통해 배달을 시켰어요' (I ordered delivery through an app).

Finally, it is worth noting that 을/를 통해 is almost never used for physical tools like a hammer or a spoon (where -로/으로 is preferred). Instead, it is used for systems, people, and abstract concepts. If you use a hammer to break a wall, you use '망치로.' But if you solve a problem through 'dialogue,' you use '대화를 통해.' This distinction is key to sounding like a native speaker. By mastering 을/를 통해, you transition from describing 'what' you do to explaining the 'how' and 'through what' of your actions, which is essential for professional and academic fluency in Korean.

Using 을/를 통해 correctly requires a basic understanding of Korean noun-particle relationships. The structure is remarkably consistent: [Noun] + [Object Marker 을/를] + 통해. The choice between 을 and 를 depends entirely on the final consonant (batchim) of the preceding noun. If the noun ends in a consonant (e.g., 인터넷 - internet), you use 을. If it ends in a vowel (e.g., 친구 - friend), you use 를. This phrase functions as an adverbial phrase within the sentence, meaning it usually appears before the verb it modifies. It provides the 'pathway' for the action. For instance, in the sentence 'I met him through a friend,' the 'friend' is the pathway, so it becomes '친구를 통해 그를 만났어요.'

One of the most important aspects of using 을/를 통해 is knowing when to choose it over similar particles like -로/으로. While both can mean 'by' or 'through,' 을/를 통해 implies a more comprehensive 'medium' or 'channel.' If you are talking about a physical instrument or a simple direction, -로/으로 is better. If you are talking about a system, a third party, or an abstract process, 을/를 통해 is the superior choice. For example, '버스로 가요' (I go by bus) is standard because the bus is a simple mode of transport. However, '뉴스를 통해 알았어요' (I found out through the news) is better because the news is a medium of information. This distinction helps clarify the speaker's intent and the complexity of the action being described.

Grammar Rule 1

Noun (Batchim) + 을 통해: e.g., 박물관을 통해 (Through the museum).

Grammar Rule 2

Noun (No Batchim) + 를 통해: e.g., 영화를 통해 (Through the movie).

In formal settings, the phrase often takes the form 을/를 통하여. This is the 'yeo' connective form of the verb 통하다. While '통해' is perfectly acceptable in almost all situations, '통하여' adds a layer of gravity and formality often found in literature, academic writing, and official speeches. For example, '실험을 통하여 증명되었습니다' (It was proven through experiments) sounds more authoritative than the version using '통해.' Furthermore, when you want to use this phrase as a modifier for another noun, you use 을/를 통한. For instance, '대화를 통한 해결' means 'a solution through dialogue.' Here, the verb 통하다 is turned into an adjective form (통한) to describe the noun 'solution' (해결). This flexibility allows you to build very descriptive and sophisticated noun phrases.

When constructing sentences, remember that 을/를 통해 can also imply a physical passage, though it is less common for simple 'going through a door.' It is used when the passage is significant to the context. For example, '창문을 통해 들어온 햇빛' (Sunlight that came in through the window) highlights the window as the medium for the light. In abstract contexts, it is used for 'experiences' (경험), 'efforts' (노력), and 'processes' (과정). If you want to say you grew as a person through hardship, you would say '고난을 통해 성장했습니다.' This usage is very common in self-introductions (자기소개서) and interviews, where candidates describe how they developed skills through specific projects or challenges. Master this, and you will be able to articulate your personal and professional history with much greater clarity.

Common Pattern 1

[Source/Medium] + 을/를 통해 + [Action/Result]

Common Pattern 2

[Experience] + 을/를 통해 + [Learning/Growth]

In summary, the sentence structure is straightforward, but the nuance is rich. By focusing on the 'channel' or 'intermediary,' 을/를 통해 allows you to connect ideas logically and professionally. Whether you are using it to describe how you heard a rumor, how you bought a ticket, or how you gained a new perspective, it remains one of the most functional tools in the Korean language. Always check your batchim for the correct object marker, and consider using '통하여' for formal writing or '통한' to modify nouns directly.

You will hear 을/를 통해 in almost every corner of Korean life, from the high-stakes world of corporate business to the casual chatter of a neighborhood cafe. Its prevalence stems from the Korean emphasis on networks, mediums, and the 'how' of information flow. In a business context, it is the standard way to discuss communication channels. You might hear a manager say, '이메일을 통해 공지하겠습니다' (I will announce it through email) or '협력사를 통해 부품을 공급받습니다' (We receive parts through a partner company). In these settings, the phrase provides necessary precision about the logistics of the operation. It sounds professional and clear, avoiding the ambiguity that sometimes comes with simpler particles. If you are working in Korea or with Korean partners, mastering this phrase is essential for clear communication about processes and responsibilities.

In the media, 을/를 통해 is a staple of news reporting and documentaries. News anchors frequently use it to cite sources or describe how information was obtained. For example, '익명의 제보자를 통해 입수한 자료에 따르면...' (According to materials obtained through an anonymous informant...). This usage lends an air of investigative rigor to the reporting. Similarly, in documentaries or educational programs, you will hear it used to explain scientific or historical processes: '현미경을 통해 세포를 관찰합니다' (We observe cells through a microscope). Because it highlights the instrument or the method, it is perfect for instructional content. If you enjoy watching Korean news or variety shows, pay attention to how often they use 을/를 통해 to explain how a guest was invited or how a prize was won.

In K-Dramas

Characters often say things like '다른 사람을 통해 들었어' (I heard it through someone else) to create tension about rumors.

In Interviews

Celebrities often say '작품을 통해 새로운 모습을 보여드리고 싶어요' (I want to show a new side of myself through this work).

In daily social life, the phrase is slightly less formal but still very common. It is the go-to expression when talking about social connections. In Korea's 'networking' culture (인맥), how you met someone is often as important as who they are. You will often hear '친구를 통해 소개받았어요' (I was introduced through a friend). Using 을/를 통해 here acknowledges the 'bridge' that made the relationship possible. It is also used when discussing modern technology. Since most Koreans are highly digitally connected, phrases like 'SNS를 통해 연락해요' (We keep in touch through SNS) or '당근마켓을 통해 중고 물건을 팔았어요' (I sold a used item through Karrot Market) are heard every day. It effectively describes the digital platforms that facilitate our daily interactions.

Finally, you will encounter this phrase in self-help books, religious contexts, and educational materials. It is the language of personal development. '명상을 통해 마음의 평화를 찾으세요' (Find peace of mind through meditation) or '실천을 통해 배우는 것이 중요합니다' (It is important to learn through practice). In these contexts, 을/를 통해 suggests a journey or a transformative process. It implies that the 'medium' (meditation, practice, hardship) is the essential catalyst for the 'result' (peace, learning, growth). Whether you are listening to a podcast, attending a lecture, or just chatting with a neighbor, 을/를 통해 is the thread that connects the 'what' to the 'how,' making it an indispensable part of your Korean listening and speaking repertoire.

Social Media

'인스타그램을 통해 공지할게요' (I'll announce it through Instagram).

Education

'강의를 통해 많은 것을 배웠습니다' (I learned a lot through the lecture).

In conclusion, 을/를 통해 is not just a grammar point; it is a window into how Korean speakers view the interconnectedness of people, technology, and experiences. By paying attention to where you hear it, you will start to see these 'bridges' everywhere in Korean society. From the news to the neighborhood, it is the primary way to explain how things get done, how people meet, and how knowledge is shared.

While 을/를 통해 is a relatively straightforward phrase, learners often make several common mistakes that can make their Korean sound unnatural or confusing. The most frequent error is confusing it with the simple instrumental particle -로/으로. As mentioned before, -로/으로 is generally used for physical tools or simple methods (using a pen, going by car), whereas 을/를 통해 is used for mediums, channels, or processes. For example, saying '펜을 통해 편지를 써요' (I write a letter through a pen) sounds very strange to a native speaker. It implies the pen is a complex medium or a third party, rather than just a tool. In this case, '펜으로 편지를 써요' is the correct choice. A good rule of thumb: if you are physically holding the object and using it, use -로/으로. If the object or person is a 'gateway' or 'intermediary,' use 을/를 통해.

Another common mistake involves the object markers 을 and 를. Because 을/를 통해 is a longer phrase, learners sometimes forget that the standard rules for batchim still apply. Using '인터넷를 통해' instead of '인터넷을 통해' or '친구을 통해' instead of '친구를 통해' are small but noticeable errors. Always double-check the final sound of the noun. If it ends in a consonant, use 을. If it ends in a vowel, use 를. This is a fundamental rule of Korean grammar that applies here just as strictly as it does with direct objects. Practicing with common nouns like 인터넷, 친구, 경험, and 뉴스 will help make the correct pairing instinctive.

Mistake 1: Wrong Particle

Using 을/를 통해 for simple tools (like a spoon or hammer) instead of -로/으로.

Mistake 2: Batchim Errors

Using 를 after a consonant or 을 after a vowel.

Mistake 3: Physical Movement

Confusing it with '-(으)로' for simple directions like 'go through the door.'

A more subtle mistake is using 을/를 통해 when -에게/한테 (to/from a person) or -(으)로부터 (from) would be more appropriate. For instance, if you received a gift directly from a friend, you would say '친구한테 선물을 받았어요.' If you say '친구를 통해 선물을 받았어요,' it implies the friend was just a delivery person or a middleman, and the gift actually came from someone else. This distinction is crucial for social etiquette and clear communication. If you want to emphasize the source of something, use -에게서 or -로부터. If you want to emphasize the middleman or the channel, use 을/를 통해. Misusing these can lead to confusion about who actually did what.

Lastly, learners sometimes overcomplicate their sentences by using 을/를 통해 when a simple verb would suffice. For example, instead of saying '공부를 통해 알게 되었어요' (I came to know through study), you could often just say '공부해서 알게 되었어요' (I studied and thus came to know). While 을/를 통해 is great for emphasis and formality, overusing it can make your speech sound a bit stiff or like a textbook. Try to balance its use with other connective forms like -아/어서 or -(으)니까 to maintain a natural flow. In summary, watch out for the tool vs. medium distinction, keep your batchim rules in mind, distinguish between middlemen and sources, and avoid over-formality in casual settings.

Formal vs. Natural

'책을 통해 배웠어요' (Formal) vs. '책 보고 배웠어요' (Natural/Casual).

Direct vs. Indirect

'민수한테 들었어요' (Direct from Minsu) vs. '민수를 통해 들었어요' (Minsu was the messenger).

Korean has several ways to express 'through' or 'by means of,' and choosing the right one depends on the nuance you want to convey. The most common alternative to 을/를 통해 is the particle -로/으로. As discussed, -로/으로 is the general-purpose instrumental particle. It is used for tools, materials, directions, and methods. While 을/를 통해 implies a 'medium' or 'channel,' -로/으로 is more direct. For example, '한국어로 말해요' (Speak in Korean) uses -로 because Korean is the 'material' or 'tool' of communication. However, '번역기를 통해 말해요' (Speak through a translator) uses 을/를 통해 because the translator is the 'medium.' Understanding this subtle shift from 'tool' to 'channel' is key to advanced fluency.

-로/으로

Focuses on the tool or direction. (e.g., 배로 - by boat)

을/를 거쳐서

Focuses on a stopover or a stage in a process. (e.g., 도쿄를 거쳐서 - via Tokyo)

-에 의해(서)

Focuses on the cause or the agent, often in passive sentences. (e.g., 중력에 의해 - by gravity)

Another similar expression is 을/를 거쳐서 (eul/reul geochyeoseo). While '통해' means 'through' as a medium, '거쳐서' means 'via' in the sense of a stopover or passing through a specific stage. If you are flying from Seoul to New York with a layover in Tokyo, you would say '도쿄를 거쳐서 가요.' If you use '통해' here, it might sound like Tokyo was the 'medium' of your travel, which is less precise. Similarly, '거쳐서' is used for career stages: '인턴을 거쳐서 정직원이 되었어요' (I became a regular employee after going through an internship). Here, the internship is a stage you passed, not just a medium of information. Choosing between '통해' and '거쳐서' allows you to distinguish between a 'channel' and a 'stopover.'

In formal or academic writing, you might encounter -에 의해(서) (-e uihae-seo). This means 'by' or 'due to' and is often used to indicate the cause of a phenomenon or the agent in a passive sentence. For example, '태풍에 의해 집이 파손되었습니다' (The house was damaged by the typhoon). While you could technically use '태풍을 통해' (through the typhoon), it would imply the typhoon was a medium for the damage, which sounds a bit poetic or strange. '-에 의해' is much more common for cause-and-effect relationships. If you are writing a research paper, '-에 의해' and '을/를 통해' will be your two most important tools for explaining how results were achieved and what caused them.

Finally, for very casual situations, Koreans often just use the -아/어서 connective. Instead of '인터넷을 통해 샀어요,' they might say '인터넷에서 샀어요' (I bought it at/from the internet) or '인터넷 보고 샀어요' (I saw it on the internet and bought it). This is much more natural in daily speech. '을/를 통해' adds a bit of weight and focus to the medium, which is great for emphasis but can be overkill for small talk. By knowing these alternatives—the directness of -로/으로, the stopover nuance of 거쳐서, the causal weight of -에 의해, and the casual ease of -아/어서—you can choose the exact 'flavor' of 'through' that fits your context perfectly.
