~을/를 통해서

The Korean grammatical structure ~을/를 통해서 is a versatile and essential expression used to indicate the medium, method, or path by which an action occurs or a result is achieved. Derived from the verb 통하다 (tong-hada), which means 'to pass through' or 'to circulate,' combined with the connective suffix -어서, it literally translates to 'having passed through.' In English, we most frequently translate this as 'through,' 'via,' 'by means of,' or 'through the medium of.' It is a staple of both spoken and written Korean, bridging the gap between simple physical movement and complex abstract processes.

Physical Passage

Used when something moves from one side of an object to another, such as light coming through a window or a person walking through a gate.

Intermediary/Agent

Used when a person or organization acts as a middleman, such as hearing news through a friend or finding a job through an agency.

Method or Experience

Used to describe learning or gaining insight through a specific activity, like learning culture through movies or gaining wisdom through travel.

This expression is particularly common in formal settings, news reports, and academic writing because it provides a clear logical link between the 'source' and the 'outcome.' However, it is equally common in daily life when explaining how you obtained information. For example, if someone asks how you knew about a party, you might say, "I heard it through Minho." This nuance of 'indirectness' is what makes ~을/를 통해서 distinct from the more direct instrumental particle ~(으)로.

Understanding the breadth of this word requires looking at its three main pillars: physical space, social connection, and experiential learning. In physical terms, it describes the conduit. In social terms, it describes the messenger. In experiential terms, it describes the catalyst. This multi-layered utility is why learners encounter it early in their studies but continue to refine its usage well into advanced levels. It allows speakers to move beyond simple subject-verb-object sentences into more descriptive narratives about how things happen in the world.

Furthermore, the frequency of this word in professional contexts cannot be overstated. When a company announces a new partnership, they will say it was achieved "through long negotiations." When a scientist explains a discovery, they will say it was found "through rigorous experimentation." It adds a layer of professionalism and clarity to the discourse, making it an indispensable tool for anyone looking to sound more natural and sophisticated in Korean. It is not just a word; it is a logical connector that defines the flow of information and action.

Grammatically, ~을/를 통해서 is attached to a noun. The choice between 을 and 를 depends on whether the preceding noun ends in a consonant (받침) or a vowel. If the noun ends in a consonant, use 을 통해서; if it ends in a vowel, use 를 통해서. This structure acts as an adverbial phrase within the sentence, usually appearing before the verb it modifies.

One of the most important aspects of using this structure correctly is understanding the verb it originates from: 통하다. Because 통하다 implies a flow or a connection, the noun used with 통해서 must be something that can logically act as a conduit. You can't just use it for any tool. For instance, while you can say "through a book" (as a source of knowledge), you wouldn't typically say "through a spoon" to mean you ate with a spoon; in that case, the instrumental particle ~(으)로 is more appropriate.

Sentence Structure

[Noun] + 을/를 통해서 + [Action/Result Verb]. Example: 독서를 통해서 지식을 쌓아요 (Build knowledge through reading).

Formal Variation

In very formal writing, you might see ~을/를 통하여. This is the same meaning but uses the more literary ending -여 instead of -어서.

When using ~을/를 통해서 with people, it implies that the person is an intermediary. If you say "I met him through a friend," it means the friend introduced you. This is a very common way to describe social networking in Korea. In a business context, it is used to describe channels of communication, such as "through the official website" or "through the customer service center." It emphasizes the 'path' rather than the 'tool.'

Finally, consider the tense. ~을/를 통해서 itself doesn't change for tense; the final verb of the sentence carries the tense. Whether you learned something in the past, are learning it now, or will learn it in the future, the 'through' part remains constant. This stability makes it a reliable building block for complex sentences. As you progress, you will notice it being used to link entire clauses by turning a verb into a noun (nominalization) and then adding ~을/를 통해서, such as 대화를 나누는 것을 통해서 (through having a conversation).

In the real world, ~을/를 통해서 is ubiquitous. If you turn on a Korean news broadcast, you will hear it within the first five minutes. News anchors use it to cite sources: "Through a government official, we have learned..." or "Through CCTV footage, the suspect was identified." It provides a sense of objectivity and evidence-based reporting. It's the language of 'how we know what we know.'

In the Workplace

"이메일을 통해서 공지하겠습니다" (I will announce it through email). This is the standard way to specify communication channels in a professional setting.

In Education

Teachers often say, "실험을 통해서 원리를 배워봅시다" (Let's learn the principle through an experiment). It emphasizes the process of discovery.

In Documentaries

Narrators use it to explain historical or natural processes: "이 강을 통해서 문명이 발달했습니다" (Civilization developed through this river).

In everyday social life, you'll hear it when people talk about their hobbies or personal growth. A K-pop fan might say, "BTS를 통해서 한국 문화를 알게 되었어요" (I came to know Korean culture through BTS). This usage is very common in interviews or fan letters. It expresses a meaningful connection between a medium (the artist) and a result (learning about a culture). It carries a slightly more profound weight than just saying "I learned it from BTS."

Another common place is in travel and navigation. While ~(으)로 is used for general directions, ~을/를 통해서 is used for specific transit points. If you are taking a flight from Seoul to New York with a layover in Tokyo, you would say, "도쿄를 통해서 가요" (I'm going via Tokyo). It highlights the intermediate stop as a necessary part of the journey. This is also true for walking directions, like "Go through the park to get to the station."

Finally, you will see it in marketing and advertisements. Brands often use it to explain the benefits of their products: "Our technology, through years of research, provides the best comfort." In this context, it builds trust by showing the 'how' behind the 'what.' Whether you are reading a billboard, watching a variety show, or talking to a colleague, ~을/를 통해서 is the invisible thread that connects the dots of Korean communication.

One of the most frequent errors learners make is confusing ~을/를 통해서 with the instrumental particle ~(으)로. While both can be translated as 'by' or 'with,' they are not always interchangeable. ~(으)로 focuses on the tool or the direct method, whereas ~을/를 통해서 focuses on the medium or the intermediate process. For example, you write with a pen (펜으로), you don't write through a pen (펜을 통해서), unless the pen is somehow a magical medium communicating for you.

Another mistake is forgetting the object particle 을/를. Because 통해서 is a verb form (통하다 + 어서), it requires an object. Learners often say "친구 통해서" (ching-gu tong-hae-seo) which is common in very casual, fast speech, but in standard Korean and especially in writing, the particle is mandatory. Omitting it can make the sentence feel incomplete or overly colloquial in formal situations.

The 'By' Confusion

Don't use 통해서 for the agent of a passive sentence. "The book was written by Han Kang" uses ~에 의해(서), not 통해서. 통해서 would imply Han Kang was just the medium, not the author.

Physical vs. Abstract

Sometimes learners use 통해서 for simple movement when ~(으)로 or ~을/를 지나서 (passing by) is better. Use 통해서 when you actually go inside and out of something, like a tunnel or a door.

A subtle mistake involves the nuance of 'source.' If you are receiving a gift from someone, you use ~에게(서) or ~한테(서). If you use 통해서, it implies that person was just the delivery man, not the giver. For example, "I got the gift through Minho" means Minho handed it to you on behalf of someone else. If Minho is the giver, 통해서 is the wrong choice.

Lastly, avoid overusing it. While it's a great word, using it in every sentence can make your Korean sound stiff and robotic. In casual conversation, Koreans often use simpler structures like ~고 or ~어서 to link actions. Save 통해서 for when you really want to highlight the path or the medium of an event. Balancing formal structures with natural flow is the key to reaching higher proficiency levels.

To truly master ~을/를 통해서, you must understand how it compares to its synonyms and near-synonyms. The most common alternative is ~(으)로, but there are others like ~을/를 거쳐서, ~에 의해서, and ~을/를 빌려(서). Each carries a specific nuance that changes the meaning of the sentence.

~을/를 통해서 vs. ~(으)로

통해서: Focuses on the medium or the process (e.g., through an intermediary).
(으)로: Focuses on the direct tool, material, or direction (e.g., with a hammer, by bus).

~을/를 통해서 vs. ~을/를 거쳐서

통해서: General 'through' (can be abstract or physical).
거쳐서: Specifically means 'via' or 'by way of' a physical location or a stage in a process (e.g., stopping at a city during a trip).

~을/를 통해서 vs. ~에 의해서

통해서: The medium.
에 의해서: The cause or the agent (often used in passive sentences, 'by someone').

For example, if you are traveling from London to Seoul with a stop in Dubai, you can use both 통해서 and 거쳐서. However, 거쳐서 sounds more like a scheduled stop on a route, while 통해서 just describes the passage. In abstract terms, like "learning through experience," 거쳐서 is rarely used; 통해서 is the standard choice here.

Another interesting comparison is with ~을/를 빌려(서), which means 'borrowing' or 'using the help of.' This is often used in very formal speeches when someone says, "I would like to use this opportunity to thank you." In Korean, they say, "이 자리를 빌려 감사의 말씀을 드립니다." While 통해서 could work, 빌려 adds a layer of humility and formality.

In summary, while ~을/를 통해서 is a very broad term, knowing these alternatives allows you to be more precise. As you listen to more Korean, pay attention to which 'through' word is used in different contexts. This sensitivity to nuance is what distinguishes a fluent speaker from a beginner. Whether it's the physical passage of light or the abstract acquisition of knowledge, choosing the right connector makes your Korean sound authentic and clear.
