~을 통해

The Korean phrase ~을/를 통해 (or its more formal variant ~을/를 통하여) is a versatile and essential grammatical structure used to express the concept of 'through' or 'by means of.' At its core, it describes a medium, a channel, or a process that facilitates an action or a result. Whether you are talking about physical passage through a space, receiving information via a specific source, or achieving a goal through hard work, this phrase is your go-to tool. It bridges the gap between a starting point and an end result by highlighting the intermediary factor. In everyday Korean, you will encounter it in diverse settings, from casual conversations about how you met a friend to formal news reports explaining how a new policy was implemented. It is categorized as an A2-level grammar point because while its basic meaning is straightforward, its application across physical and abstract contexts requires a nuanced understanding of Korean sentence structure.

Physical Passage

Used when something moves from one side to another through an opening or a space. For example, light coming through a window or air flowing through a vent.

Intermediary Person

Used when a person acts as a bridge between two other parties. If you heard news from a friend or met a business partner through a colleague, this is the phrase you use.

Method or Means

Used to describe the tool or process used to achieve something. This includes learning through books, watching news through the internet, or gaining experience through travel.

The phrase is derived from the verb 통하다, which means 'to pass through,' 'to flow,' or 'to communicate.' By adding the connective suffix -어 and the optional -야 (which is usually shortened to ~해), it transforms into a postpositional phrase that attaches to nouns. One of the reasons this phrase is so common is its ability to handle both concrete and abstract nouns. You can pass through a door (concrete) just as easily as you can pass through a difficult period in life (abstract). In the modern digital age, its usage has exploded with the rise of social media and the internet, as we constantly receive information 'through' various digital platforms.

Furthermore, ~을/를 통해 is often preferred in formal writing and presentations over the simpler particle ~으로 (by/with) because it sounds more precise and sophisticated. While ~으로 focuses on the tool itself, ~을/를 통해 emphasizes the entire process or the channel of delivery. For instance, saying '인터넷으로 배웠어요' (I learned by internet) is perfectly fine, but '인터넷을 통해 배웠어요' (I learned through the internet) suggests a more structured or indirect acquisition of knowledge. This subtle difference is what helps intermediate learners sound more like native speakers. As you progress in your Korean journey, you will find that mastering this phrase allows you to describe complex relationships between causes, effects, and the channels that connect them.

Using ~을/를 통해 correctly requires attention to the noun it follows and the particle that attaches to that noun. The rule is simple: if the noun ends in a consonant (patchim), use ~을 통해. If the noun ends in a vowel, use ~를 통해. This follows the standard Korean object marker logic, as the phrase functions as a transitive structure where the noun is the 'object' being passed through. However, unlike a direct object, the noun here acts as the medium. Let's look at the structural breakdown: [Noun] + [을/를] + [통해] + [Verb/Result].

With Consonant-Ending Nouns

책 (Book) + 을 통해 = 책을 통해 (Through a book). Example: 책을 통해 지식을 얻어요 (I gain knowledge through books).

With Vowel-Ending Nouns

뉴스 (News) + 를 통해 = 뉴스를 통해 (Through the news). Example: 뉴스를 통해 사고 소식을 알게 됐어요 (I learned about the accident through the news).

In more formal or written contexts, you will often see ~을/를 통하여. This is the uncontracted version and is highly common in academic papers, news broadcasts, and official speeches. While ~통해 is perfectly acceptable in most situations, ~통하여 adds a layer of gravity and professionalism. Another important aspect is the verb that follows. Since ~을/를 통해 indicates a process, the following verb often relates to acquisition (얻다, 배우다, 알게 되다), communication (전하다, 듣다, 말하다), or movement (지나가다, 들어오다). It is rarely used with simple state verbs like 'to be' (이다) unless describing a complex identity formed through experience.

When describing physical movement, ~을/를 통해 emphasizes the 'passing through' part of the journey. For example, '창문을 통해 밖을 봐요' (I look outside through the window). Here, the window is the medium for your vision. If you were to say '창문으로 봐요,' it would mean 'I look with the window,' which sounds slightly less natural in this specific context of visual passage. This phrase is also indispensable when discussing personal growth. Phrases like '실패를 통해 배웠어요' (I learned through failure) or '경험을 통해 깨달았어요' (I realized through experience) are staples of Korean self-reflection and storytelling. By using this structure, you shift the focus from the action itself to the valuable process that made the action possible.

The phrase ~을/를 통해 is ubiquitous in South Korea, appearing in almost every facet of daily and professional life. If you turn on the television to watch the evening news, you will hear it within the first few minutes. News anchors use it to cite sources: '익명의 제보자를 통해 확인된 바에 따르면...' (According to what was confirmed through an anonymous informant...). In this context, it lends an air of journalistic objectivity and distance. It is also the standard way to describe how information travels in the digital age. Advertisements frequently use it to tell consumers how they can access services: '앱을 통해 예약하세요' (Please make a reservation through the app) or '홈페이지를 통해 신청 가능합니다' (Applications are possible through the homepage).

In the Workplace

Colleagues use it to discuss project updates or communication channels. '이메일을 통해 자료를 보냈습니다' (I sent the materials through email) is a standard professional sentence.

In Educational Settings

Teachers often say, '실험을 통해 원리를 이해해 봅시다' (Let's understand the principle through an experiment). It emphasizes the pedagogical process of discovery.

In social situations, ~을/를 통해 is used to explain connections between people. In Korea's 'network-based' society, knowing someone 'through' someone else is very common. You might hear, '민수 씨를 통해 소개받았어요' (I was introduced through Minsu). This highlights the social bridge that connects two individuals. Furthermore, in the world of K-Dramas and K-Pop, fans often hear idols say, '음악을 통해 여러분과 소통하고 싶어요' (I want to communicate with you all through music). Here, music is the emotional and artistic medium that connects the artist to the audience. It sounds more poetic and meaningful than using a simple particle.

Even in literature and philosophy, this phrase plays a major role. Authors use it to describe internal growth: '고난을 통해 성장하는 주인공' (A protagonist who grows through hardships). It suggests that the hardship wasn't just an obstacle, but the very path to maturity. Whether you are reading a self-help book, a technical manual, or a celebrity interview, ~을/를 통해 is the connective tissue that explains how things happen. By paying attention to this phrase in your listening practice, you will start to notice how Koreans conceptualize the 'flow' of information, people, and experiences in their lives.

One of the most frequent mistakes learners make is confusing ~을/를 통해 with the particle ~으로/로. While they can both be translated as 'by' or 'through' in English, their usage in Korean is distinct. ~으로/로 usually indicates a direct tool or a direction (e.g., '펜으로 써요' - write with a pen), whereas ~을/를 통해 indicates a medium or a channel (e.g., '친구를 통해 들어요' - hear through a friend). You wouldn't say '펜을 통해 써요' unless the pen was somehow a magical medium through which a spirit was writing! Another common error is using the wrong object marker. Remember, ~을 follows a consonant and ~를 follows a vowel. Saying '친구을 통해' is a basic grammatical slip that can make your speech sound unnatural.

Confusing with ~을 거쳐 (Via/Passing through)

Learners often use ~을 통해 when they should use ~을 거쳐. While ~을 통해 is general, ~을 거쳐 specifically implies stopping at a location on the way to somewhere else (e.g., '런던을 거쳐 서울에 가요' - go to Seoul via London).

Overusing in Simple Contexts

Sometimes learners use ~을 통해 for direct actions where a simple verb or particle would suffice. For example, '입을 통해 먹어요' (I eat through my mouth) is technically correct but sounds like a medical description rather than a normal way to say 'I eat.'

Another nuance is the difference between ~을 통해 and ~때문에 (because of). Learners sometimes use ~을 통해 to express a simple cause, but ~을 통해 implies a process or a medium, not just a reason. If you want to say 'I was late because of the rain,' you use '비 때문에.' If you say '비를 통해,' it would imply that the rain was a channel for something else to happen, which doesn't make sense in that context. Furthermore, be careful with the formal version ~을 통하여. While it's great for writing, using it too much in casual conversation with friends might make you sound like a textbook or a news reporter.

Lastly, ensure that the noun preceding ~을/를 통해 is actually a medium. A common mistake is using it with verbs turned into nouns incorrectly. For instance, '공부하는 것을 통해' (through the act of studying) is better expressed as '공부를 통해' (through study) or '공부함으로써' (by studying). Keeping the noun simple and direct makes the sentence flow much better. By avoiding these common pitfalls, you will be able to use this phrase with the precision and naturalness of a native speaker, clearly articulating the pathways through which things happen in your world.

Korean has several ways to express 'through,' 'by,' or 'via,' and choosing the right one depends on the context. While ~을/를 통해 is the most versatile, knowing its alternatives will significantly enrich your vocabulary and allow for more precise expression. The most common alternative is the particle ~으로/로, which we've discussed, but there are several others that are more specific. For example, ~을/를 거쳐 is used specifically for physical or sequential 'via' points. If you are traveling from New York to Seoul via Tokyo, ~을 거쳐 is the correct choice. It implies a stopover or a specific stage in a sequence.

~을/를 거쳐 (Via / By way of)

Used for physical locations or historical stages. Example: '과거를 거쳐 현재에 이르다' (To reach the present via the past).

~에 의해서 (By / Due to)

A more formal way to indicate agency or cause, often used in passive sentences. Example: '법에 의해서 금지되다' (To be prohibited by law).

~을/를 매개로 (Through the medium of)

Very formal and academic. It specifically highlights the noun as a 'mediator' or 'link.' Example: '예술을 매개로 소통하다' (To communicate through the medium of art).

Another interesting alternative is ~을/를 빌려(서), which literally means 'borrowing.' It is used when you use someone else's words, a specific occasion, or a platform to express something. For example, '이 자리를 빌려 감사의 인사를 전합니다' (I take this opportunity—literally 'borrow this place'—to express my gratitude). This is a very common set phrase in speeches. Additionally, ~으로 말미암아 is a literary and formal way to say 'due to' or 'arising from,' often used for negative consequences or grand historical shifts. It's much heavier than ~을 통해.

In casual speech, you might also hear ~해서 or ~가지고 used in a way that mimics 'through' or 'by,' but these are much less precise. For example, '인터넷 봐서 알았어' (I saw the internet and knew) instead of '인터넷을 통해 알았어.' While the former is common in spoken Korean, the latter is clearer and more grammatically 'complete.' Understanding these synonyms allows you to tailor your language to the specific situation—whether you're writing a formal report, giving a wedding toast, or just chatting with a friend about how you found a great new restaurant. By mastering the spectrum of 'through' in Korean, you gain the ability to describe the intricate web of connections that define our experiences.
