Core Grammar Rule: N + 에 따라
This pattern is used to indicate that the outcome described in the second clause changes "depending on" or "according to" the noun in the first clause. It highlights a standard, condition, or basis for variation.
Meaning & Usage
Meaning: It translates to "depending on N," "according to N," or "in accordance with N."
When to use: Use it when you want to explain that a situation, result, or procedure is not fixed, but rather flexible based on a certain factor (the noun). It's common in explanations, instructions, and descriptions of systems or rules. For example, 사람에 따라 생각이 달라요 (Opinions differ depending on the person).
Conjugation Rules
Rule: This pattern is very simple. You just attach ~에 따라 directly to the end of a noun, regardless of whether it ends in a vowel or a consonant.
Noun + 에 따라
Native Nuance & Mistakes: Tense in ~는 줄 알다/모르다
A common point of confusion for learners is the tense of 알다/모르다. Using the past tense (알았다/몰랐다) versus the present tense (안다/모른다) completely changes the meaning.
Past Tense for Past Misconceptions: ~는 줄 알았다/몰랐다
Context: Use the past tense (알았다 or 몰랐다) to express that you used to think something was true, but now you know it's not (or vice versa). The key is that your understanding has changed. It's about a past state of belief.
Example: 저는 그가 의사인 줄 알았어요. (I thought he was a doctor, but he isn't). This implies you've learned the truth.
Present Tense for Current Knowledge: ~는 줄 안다/모른다
Context: Use the present tense (안다 or 모른다) to state what you know or don't know right now. It's a statement of your current awareness, not a past misconception.
Example: 저는 그가 의사인 줄 알아요. (I know that he is a doctor). This is a statement of fact. Mixing these up is a common mistake.
Do: 어제까지는 그가 학생인 줄 알았어. (O) / Don't: 어제까지는 그가 학생인 줄 알아. (X)
Common Combination: N + 에 따라 다르다
The pattern ~에 따라 is very frequently paired with the verb 다르다 (to be different) to express that something varies depending on a specific noun (a condition, standard, or factor).
