~을/를 통해

The Korean expression ~을/를 통해 is a foundational grammatical structure used to indicate the medium, method, or physical passage by which an action occurs. At its core, it is derived from the verb 통하다, which means 'to pass through' or 'to flow.' When used as a postpositional phrase, it functions similarly to the English words 'through,' 'via,' or 'by means of.' This expression is ubiquitous in both spoken and written Korean, serving as a bridge to explain how information was acquired, how a destination was reached, or how a result was achieved. It is categorized as CEFR A2 because while the concept is simple, its application spans from basic physical movement to complex abstract reasoning. Understanding this phrase allows learners to move beyond simple subject-verb-object sentences and begin describing the 'how' and 'where' of their experiences with greater precision and nuance.

Physical Passage

This is the most literal use, describing movement through a space. For example, 'passing through a door' or 'looking through a window.' It implies entering one side and exiting another.

Medium of Communication

In the modern world, we receive information via various channels. Whether it is the internet, a friend, or the news, this expression identifies the source or channel of that information.

Abstract Means or Experience

This is where the expression becomes powerful for intermediate learners. It describes achieving a state or learning a lesson through an experience or a process, such as 'learning through failure' or 'growing through travel.'

People use this word when they want to be specific about the agency or the path of an action. It avoids the ambiguity of the simple particle '~로' (which can mean direction, tool, or change of state) by focusing specifically on the 'passage' or 'intermediary' aspect. In professional settings, it is the standard way to cite sources or explain methodologies. In personal settings, it is used to explain how you met someone or how you found out about an event. Its versatility makes it one of the most high-frequency patterns in the Korean language, essential for anyone aiming for fluency.

Using ~을/를 통해 requires a basic understanding of Korean noun-particle relationships. The structure is remarkably consistent: [Noun] + [Object Particle 을/를] + [통해]. The choice between 을 and 를 depends entirely on whether the preceding noun ends in a consonant (받침) or a vowel. If the noun ends in a consonant, use 을; if it ends in a vowel, use 를. This consistency makes it an accessible pattern for A2 learners to master quickly. However, the sophistication of your sentences will grow as you apply this pattern to more complex nouns and abstract concepts.

The Grammatical Breakdown

The word '통해' is the adverbial form of '통하다'. By adding '을/를', we treat the medium as the object of the 'passing through' action. This creates a logical flow: 'Using [Noun] as the path, [Action] happens.'

One of the most important aspects of using this expression is knowing what kind of nouns can precede it. It is most commonly used with nouns representing physical objects (windows, doors, pipes), communication channels (phones, internet, SNS), people (friends, teachers, intermediaries), or abstract experiences (education, volunteer work, trials). It is rarely used with time durations; for that, other expressions like '내내' or '동안' are preferred. Furthermore, while '통해' is an adverbial phrase, it can be turned into an adjective-like phrase by adding '통한' to modify a following noun: '[Noun]을 통한 [Noun]'.

Modifying Nouns with '~을 통한'

When you want to say 'Success through hard work' as a single noun phrase, you use '통한'. For example: '노력을 통한 성공'. This is very common in titles and formal documents.

In everyday conversation, you will often hear '통해서' instead of just '통해'. The addition of the suffix '-서' emphasizes the sequential or causal nature of the action. While '통해' sounds a bit more clipped and formal, '통해서' flows more naturally in spoken sentences. For example, '친구를 통해서 들었어요' (I heard it through a friend) sounds very natural in a coffee shop setting. Conversely, a news anchor reporting on a government policy would likely say '정부를 통해 발표되었습니다' (It was announced through the government).

Common Sentence Patterns

1. [Source]을/를 통해 알게 되다 (To come to know through [Source])
2. [Method]을/를 통해 해결하다 (To solve through [Method])
3. [Path]을/를 통해 이동하다 (To move through [Path])

The phrase ~을/를 통해 is a staple of Korean media, professional environments, and educational settings. If you turn on a Korean news broadcast, you will hear it within the first five minutes. Journalists use it to attribute information to sources without necessarily naming specific individuals, such as '정부 관계자를 통해' (through a government official). It provides a level of professional distance and objectivity. In the business world, it is used to describe logistics, communication channels with clients, and the results of market research. For instance, a manager might say, '설문조사를 통해 고객의 의견을 수렴했습니다' (We gathered customer opinions through a survey).

In the Classroom

Teachers constantly use this expression to explain the learning process. '실험을 통해 과학 원리를 배워요' (We learn science principles through experiments). It emphasizes the methodology of education.

In the realm of digital life, which is central to modern Korean culture, '~을/를 통해' is used to describe how people interact with apps and platforms. Whether it's ordering food '앱을 통해' (through an app) or meeting a partner '소개팅 앱을 통해' (through a blind date app), the phrase identifies the digital intermediary. It is also common in social media captions where influencers might say they found a great product '협찬을 통해' (through a sponsorship) or learned a new tip '댓글을 통해' (through the comments).

In Literature and Drama

K-Dramas often use this phrase in pivotal moments of realization. A character might say, '너를 통해 사랑을 배웠어' (I learned about love through you). Here, the person becomes the 'medium' for an emotional awakening.

Finally, in travel and transportation, you will hear this word at airports and train stations. '인천을 통해 입국하다' (To enter the country through Incheon) or '터널을 통해 이동하다' (To move through a tunnel). It is the standard way to describe transit points. Even in casual gossip, if someone asks how you knew a secret, the answer often starts with '누구를 통해...' (Through someone...). It is a word that connects the dots in Korean society, making it indispensable for understanding the flow of information and movement.

Public Announcements

'안내 방송을 통해 알려드립니다' (We are informing you through the announcement broadcast). This is a very common formal opening in public spaces.

While ~을/를 통해 is relatively straightforward, English speakers often make mistakes by over-relying on it or using it in contexts where other particles are more appropriate. The most common mistake is confusing it with the particle ~으로. While both can mean 'by' or 'through,' ~으로 is used for tools, directions, or materials, whereas ~을 통해 specifically implies a medium or a passage. For example, if you say '젓가락을 통해 먹어요,' it sounds like you are eating *through* the chopsticks (as if they were a tube), which is incorrect. You should use '젓가락으로 먹어요' (I eat with chopsticks).

Mistake 1: Confusing Tool with Medium

Use '~으로' for tools (hammer, pen, chopsticks). Use '~을 통해' for intermediaries (internet, friends, windows).

Another frequent error is using '~을 통해' to describe a duration of time. In English, we can say 'throughout the year' or 'through the night.' However, in Korean, '~을 통해' does not carry this temporal meaning. Using it to mean 'all through the time' will confuse native speakers. Instead, you should use '내내' (throughout) or '동안' (during). For example, '일 년 내내' is 'throughout the year,' not '일 년을 통해'.

Mistake 2: Temporal Misuse

Do not use '~을 통해' for 'throughout a period of time.' Use '내내' or '동안' instead.

Learners also sometimes forget the object particle '을/를'. Because '통해' feels like a standalone word, some might say '친구 통해' instead of '친구를 통해'. While this is occasionally heard in very fast, casual speech, it is grammatically incomplete and can sound uneducated in formal contexts. Always ensure the noun is properly marked as the object of the 'passage.' Lastly, be careful with the word '통해서'. While it is often interchangeable, using '통해서' when you need the adjective form '통한' is a common mistake in writing. You cannot say '대화를 통해서 해결' to mean 'A solution through dialogue' if it's a noun phrase; it must be '대화를 통한 해결'.

Mistake 3: Redundancy

Avoid saying '방법을 통해' (through a method) if the method itself is already clear. It can sound repetitive. Just name the method.

In Korean, there are several ways to express the idea of 'through' or 'by means of,' and choosing the right one depends on the specific nuance you want to convey. ~을/를 통해 is the most versatile, but it is not always the most natural choice. Understanding its synonyms and alternatives will help you sound more like a native speaker and allow you to express more precise meanings. The most common alternative is the particle ~으로/로, which we discussed in the common mistakes section. While '~을 통해' emphasizes the medium, '~으로' emphasizes the tool or the direction.

~을/를 통해 vs. ~으로/로

~을 통해: Focuses on the intermediary or the process (e.g., via the internet).
~으로: Focuses on the instrument or the material (e.g., with a hammer, in Korean).

Another similar expression is ~을/를 거쳐(서). This specifically means 'passing through' a physical location or a stage in a process. While '~을 통해' can be abstract, '~을 거쳐' is almost always about a sequence or a route. For example, if you fly from Seoul to New York with a layover in Tokyo, you would say '도쿄를 거쳐서 뉴욕에 갔어요.' Using '~을 통해' here would sound slightly odd because it doesn't emphasize the stopover as clearly as '거쳐서' does.

~을/를 통해 vs. ~을/를 거쳐

~을 통해: General medium or passage.
~을 거쳐: A specific stopover or a stage in a sequence.

For expressing 'thanks to' or 'due to,' you might use ~덕분에 or ~말미암아. '~덕분에' is used when the medium or person provided a positive benefit. While you could say '친구를 통해 취직했어요' (I got a job through a friend), saying '친구 덕분에 취직했어요' (I got a job thanks to my friend) adds a layer of gratitude. '~말미암아' is a very formal, literary term meaning 'as a result of' or 'due to,' often used in academic or legal writing to describe causation.

~을/를 통해 vs. ~덕분에

~을 통해: Neutral medium (how it happened).
~덕분에: Positive cause (grateful for the help).

Summary of Alternatives

1. ~으로: Tool/Material
2. ~을 거쳐: Physical route/Stages
3. ~덕분에: Positive cause
4. ~에 의해: By (passive agency, formal)
