~에 따라

The Korean phrase ~에 따라 is a versatile and essential grammatical construction that roughly translates to 'according to,' 'depending on,' or 'in accordance with' in English. It is formed by taking the noun and attaching the particle '에' followed by '따라', which is the connective form of the verb '따르다' (to follow). This phrase is used to indicate that the following action, state, or result is determined by, influenced by, or compliant with the preceding noun. In everyday life, Koreans use this to express how things change based on certain variables or how they are following a set of guidelines.

Dependency and Variation

This is perhaps the most common usage. It shows that 'B' happens or is a certain way because of 'A'. For example, if you say that prices change depending on the season, you would use this phrase to link 'season' and 'price change'. It highlights the conditional nature of the statement.

Furthermore, ~에 따라 is frequently used in formal reporting, news, and academic writing to cite a source or a standard. When a journalist says 'according to the report,' they use this phrase to provide credibility and ground their statement in a specific reference. It moves the conversation from personal opinion to objective observation. It is also found in legal contexts where actions are performed 'according to the law' (법에 따라). This usage emphasizes adherence to established rules or protocols.

Compliance and Rules

When you are following instructions, a manual, or a tradition, this phrase acts as the bridge. It signifies that the subject is not acting randomly but is following a specific path or set of instructions laid out previously.

The phrase also appears in the form -(으)ㅁ에 따라 when attached to verbs. This is an advanced grammatical point where a verb is turned into a noun (nominalized) and then followed by '에 따라'. This translates to 'as [verb] happens' or 'in accordance with the fact that [verb]'. For instance, 'As technology develops' would be '기술이 발달함에 따라'. This allows for expressing dynamic relationships where one change triggers another. Understanding this phrase is key to moving from basic Korean to an intermediate level where you can discuss complex cause-and-effect relationships.

Contextual Nuance

In many cases, this phrase highlights the 'relativity' of a situation. Korean culture often values situational awareness, and '~에 따라' is the linguistic tool that acknowledges that 'it depends.' It is a polite way to avoid making overgeneralized statements.

Using ~에 따라 correctly requires understanding its position within the sentence and the type of words it attaches to. Most commonly, it attaches directly to a Noun. The structure is simple: [Noun] + 에 따라 + [Resulting Clause]. There is no need to worry about whether the noun ends in a vowel or a consonant; '에 따라' remains consistent across all nouns, making it grammatically straightforward compared to other Korean particles.

Basic Noun Attachment

To say 'according to the plan,' you take '계획' (plan) and add '에 따라' to get '계획에 따라'. This is then followed by what you are doing, such as '진행합니다' (we are proceeding). Full sentence: '계획에 따라 진행합니다.'

When you want to express that something varies, the verb at the end of the sentence is often 다르다 (to be different) or 달라지다 (to become different). This creates the common pattern '[Noun]에 따라 달라요,' which means 'It depends on [Noun].' For example, '상황에 따라 달라요' (It depends on the situation). This is a very useful phrase in conversational Korean when you cannot give a definitive yes or no answer.

Expressing Variation

Use this when one thing dictates the state of another. '지역에 따라 날씨가 다릅니다' (The weather is different depending on the region). Here, 'region' is the variable that changes the 'weather'.

Another important nuance is the use of ~에 따라서. While it means the same thing, adding '서' at the end often makes the phrase feel like a conjunction that links two independent ideas more strongly. It is frequently seen at the start of a sentence: '따라서, 우리는...' (Therefore, we...). In this case, it's shortened from '앞의 내용에 따라서' (According to the preceding content), functioning as a transition word like 'therefore' or 'consequently'.

Formal vs. Informal

In casual speech, people might prefer '-(으)니까' or '~때문에' for simple cause-and-effect, but '~에 따라' is preferred when you want to sound precise, objective, or describe a gradual correlation. It is the hallmark of a more sophisticated speaker.

The phrase ~에 따라 is ubiquitous across various domains of Korean society. You will hear it most prominently in news broadcasts and formal presentations. News anchors use it constantly to attribute information to specific sources. Phrases like '기상청 보도에 따라' (According to the Meteorological Administration's report) or '정부 발표에 따라' (According to the government announcement) are standard opening lines for daily news segments. This usage establishes the factual basis of the news being reported.

In Professional Environments

If you work in a Korean office, you will encounter this phrase in every meeting. Managers will discuss projects '계획에 따라' (according to the plan) or '예산에 따라' (depending on the budget). It is the language of logistics and professional accountability. It removes personal bias and focuses on the agreed-upon standards.

In the academic world, research papers and university lectures rely heavily on ~에 따라. Researchers describe how results changed '실험 조건에 따라' (depending on experimental conditions) or how theories evolved '시대의 흐름에 따라' (according to the flow of the times). It is essential for describing correlations in data. If you are a student in Korea, mastering this phrase is vital for writing essays that sound professional and logical.

In Daily Life and Shopping

Even in casual settings like shopping or dining, you will hear it. A shopkeeper might tell you that the price is '무게에 따라 달라요' (different depending on the weight). A waiter might explain that the spiciness of a dish can be adjusted '취향에 따라' (according to your preference). It is the polite way to explain that there isn't a single fixed rule or price.

Finally, the world of technology and digital services uses this phrase in terms of service and user settings. Options like '설정에 따라' (depending on settings) or '사용량에 따라' (depending on usage) are common in app interfaces. As Korea is a highly digitalized society, encountering this phrase on your smartphone or computer screen is an everyday occurrence. It helps users understand how the software reacts to their inputs.

In Public Announcements

Public transportation announcements often use it to explain changes in service. '기상 악화에 따라 열차 운행이 지연될 수 있습니다' (Train operations may be delayed according to/due to worsening weather). It provides a logical reason for disruptions.

One of the most frequent mistakes learners make with ~에 따라 is confusing it with other similar-looking or similar-meaning particles. A common point of confusion is between ~에 따라 and ~에 의해서 (by/due to). While both can show a cause, '~에 의해서' is specifically used to indicate an agent or a direct cause of a passive action, whereas '~에 따라' implies following a standard or a variable dependency. For example, saying 'the window was broken BY the wind' requires '~에 의해서', but 'prices change ACCORDING TO the wind' (metaphorically) would use '~에 따라'.

Confusion with ~에 의해서

Incorrect: 법에 의해서 처벌받았어요 (He was punished BY the law - focused on agent). Correct: 법에 따라 처리했어요 (I processed it ACCORDING TO the law - focused on following the rule).

Another mistake is using the wrong particle before '따라'. Beginners often try to use the object particle '를/을' because '따르다' (to follow) is a verb. They might say '규칙을 따라' instead of '규칙에 따라'. While '규칙을 따르다' is a perfectly valid sentence meaning 'to follow the rules,' when you want to use it as a grammar connector meaning 'according to,' you MUST use the particle '에'. Using '를' makes it sound like a direct action rather than a conditional phrase.

Particle Errors

Remember: [Noun] + 에 따라 is the fixed grammar pattern for 'according to'. Using 을/를 changes the meaning to a direct physical or metaphorical following, which doesn't work as a sentence connector in the same way.

Finally, there's the 'double dependency' error. In English, we might say 'Depending on whether it rains or not.' In Korean, some learners try to put complex clauses directly before '에 따라'. However, '~에 따라' only takes nouns. If you want to use a 'whether or not' clause, you must nominalize it. For example, instead of '비가 오는지에 따라' (which is actually a common spoken shortcut), the more formal and grammatically complete version would be '우천 여부에 따라' (depending on the matter of rain or not).

Overusing the Verb Form

The -(으)ㅁ에 따라 form is for formal writing. Using it in casual conversation with friends sounds very robotic and strangely academic. Stick to the noun form [Noun]에 따라 for daily chats.

Korean has several ways to express 'according to' or 'depending on,' and choosing the right one depends on the context and the level of formality you wish to convey. The most common alternative to ~에 따라 is ~대로. While both can mean 'as' or 'according to,' '~대로' often emphasizes doing something exactly as something else is, or as soon as something happens. For example, '말씀하신 대로' (as you said) is more common than '말씀하신 것에 따라' in casual conversation.

~에 따라 vs. ~대로

'~에 따라' is more about dependency and logical standards. '~대로' is more about imitation or following a specific state. '계획대로' (as planned) sounds like following a script, while '계획에 따라' (according to the plan) sounds like following a policy or a logical sequence.

Another important alternative is ~에 의하면. This is specifically used for citing sources of information, like 'according to the news' or 'according to my friend.' While you can use '~에 따라' for this, '~에 의하면' is more specialized for reporting hearsay or facts from a third party. If you want to say 'According to the weather forecast, it will rain,' '일기예보에 의하면' is the most natural choice.

~에 따라 vs. ~에 의하면

'~에 따라' focuses on the *consequence* or *action* that follows the standard. '~에 의하면' focuses on the *source* of the information being presented. Use the latter for 'According to [Source], [Information].'

If the meaning is 'depending on,' you can sometimes use ~에 달려 있다. This is a verb phrase meaning 'to depend on.' For example, 'It depends on your effort' would be '너의 노력에 달려 있어.' This is used when the noun is the *deciding factor* for a final outcome, whereas '~에 따라' is used to show how things change along the way.

Summary of Choice

Use '~에 따라' for general dependency and following rules. Use '~대로' for 'exactly as'. Use '~에 의하면' for citing sources. Use '~에 달려 있다' for 'is contingent upon'.
