Overview
The expression 을/를 위해(서) is a connective ending used to indicate the purpose, beneficiary, or goal of an action. It attaches to nouns and signifies that the action described in the following clause is performed for the sake of that noun, or in order to benefit or achieve something related to that noun.
Usage
을/를 위해(서) is always attached to a noun. It clearly states who or what an action is intended for. The optional particle (서) can be added, which slightly emphasizes the reason or cause for the action, but often, 을/를 위해 and 을/를 위해서 are used interchangeably with little difference in meaning.
This pattern is crucial for expressing:
- Beneficiary: "I do this for my family." (가족을 위해)
- Goal/Purpose: "I study for my future." (미래를 위해)
- Target: "We prepared this for the event." (행사를 위해)
It is distinct from -기 위해(서), which is used with verbs to express the purpose of an action.
Conjugation Rules
을/를 위해(서) attaches directly to nouns:
- If the noun ends in a consonant, use 을 위해(서).

- If the noun ends in a vowel, use 를 위해(서).

Knowledge Plus
- Distinction with -기 위해(서): While both express purpose, 을/를 위해(서) is used with nouns, indicating the object or beneficiary of the purpose. -기 위해(서) is used with verbs, indicating the action that is the purpose. For example, "To study" (공부하기 위해) vs. "For studying" (공부를 위해 - less common, usually "공부를 위해서" meaning "for the sake of the study").
- The Role of (서): The addition of 서 can subtly add a nuance of "because of" or "due to" that purpose, making the connection between the purpose and the action slightly stronger. However, in everyday conversation, the difference is often negligible, and both forms are widely accepted.
- Common Phrases: You'll often hear this expression in phrases like "누구를 위해?" (For whom?), "무엇을 위해?" (For what?), or in speeches and formal declarations emphasizing a cause or goal.
