Verb Stem + 고자

Overview

-고자 (romanization: -goja) is a Korean connective ending used to express a strong, formal intention or purpose behind a subsequent action. It functions similarly to "in order to," "with the intention of," or "desiring to" in English. Unlike its more casual counterparts, -(으)려고 and -기 위해서, -고자 carries a distinct nuance of volition, determination, and often, a degree of solemnity or officiality.

Its usage immediately signals a formal register, making it common in speeches, official documents, news reports, academic writing, and other contexts where precise and respectful language is paramount. When you encounter -고자, understand that the speaker or writer is articulating a deliberate, often significant, goal that drives the following statement.

This grammatical pattern exists within Korean to provide a linguistic tool for expressing unambiguous intent in formal settings. It distinguishes a casual desire from a considered, determined objective. The very choice to use -고자 imbues the statement with weight, conveying the speaker's commitment to the goal and their awareness of the gravity of the context.

It serves to elevate the discourse, signaling that the communication is not only about an action but about the profound purpose motivating that action.

How This Grammar Works

At its core, -고자 functions as a volitional connective ending, linking a preceding clause that states an intention or purpose to a subsequent clause that describes the action taken to achieve that intention. The structure implicitly emphasizes the subject's will and agency. The action in the second clause is directly undertaken because of the purpose stated in the first clause.
The grammatical relationship is one of means to an end, where the 고자 clause defines the end.
This pattern is intrinsically linked to the speaker's subjective will. It expresses what the speaker (or the subject of the sentence) wants to do or intends to achieve. This is a crucial distinction from patterns that describe objective conditions or external necessities.
For example, 이 문제를 해결하고자 회의를 소집했습니다 (I convened a meeting in order to solve this problem) clearly states the speaker's personal drive behind calling the meeting.
One of the defining characteristics of -고자 is its forward-looking nature. The intention always precedes the action, both logically and temporally. It cannot be used to describe an intention that has already been fulfilled or an action that has already occurred.
The final verb of the sentence, which describes the action taken to realize the intention, will determine the overall tense of the sentence. The -고자 clause itself does not take any tense markers. The speaker's commitment to the stated goal is a key linguistic function of this form.
Consider the sentence 국민들에게 진실을 알리고자 이 자리에 섰습니다 (I stand here in order to inform the citizens of the truth). Here, -고자 explicitly states the speaker's primary, formal purpose. The action of standing (섰습니다) is directly in service of that stated intention.
The formality of 알리고자 elevates the statement beyond a simple factual declaration, transforming it into a statement of ethical commitment or official duty. This kind of expression is central to Korean formal communication, where respect for the audience and gravity of the message are highly valued.

Formation Pattern

1
The formation of -고자 is remarkably straightforward, making it one of the simpler formal connective endings to conjugate. It attaches directly to the verb stem (동사 어간 - dongsa eogan) without any consideration for whether the stem ends in a vowel or a consonant. This simplifies the conjugation process significantly.
2
To form the -고자 clause:
3
Take the base form of the verb (동사 원형 - dongsa wonhyeong).
4
Remove the ending -다 (da) to obtain the verb stem.
5
Attach -고자 directly to this verb stem.
6
This rule applies universally to all action verbs in Korean, including those with irregular stems (such as irregulars, irregulars, and irregulars), as -고자 does not trigger any stem changes.
7
| Verb (Base Form) | Verb Stem | -고자 Form | Romanization | Meaning |
8
| :---------------- | :----------- | :-------------------- | :-------------------- | :---------------- |
9
| 가다 (to go) | (ga) | 가고자 (gagoja) | gagoja | in order to go |
10
| 먹다 (to eat) | (meok) | 먹고자 (meokgoja) | meokgoja | in order to eat |
11
| 읽다 (to read) | (ilk) | 읽고자 (ilkgoja) | ilkgoja | in order to read |

Examples of formation in sentences:
17
시민의 의견을 수렴하고자 토론회를 개최했습니다. (In order to gather citizens' opinions, we held a debate.)
18
사회 문제 해결에 기여하고자 본 연구를 시작합니다. (We are starting this research in order to contribute to solving social problems.)
19
새로운 기술을 배우고자 온라인 강의를 신청했습니다. (I registered for an online lecture in order to learn new technology.)
20
It is important to remember that -고자 itself is an invariant form; any politeness level or tense is conveyed by the main verb in the subsequent clause. For instance, 하고자 합니다 (hagoja hamnida) is formal polite, while 하고자 한다 (hagoja handa) is formal plain (used in writing or declarative statements) or 하고자 해 (hagoja hae) is casual plain, though this latter form would rarely be used due to the inherent formality of -고자 itself.

When To Use It

-고자 is reserved for specific contexts where the expression of a formal and deliberate intention is required or desired. Its usage immediately elevates the tone of communication, making it unsuitable for most daily conversations. You should employ -고자 when you need to convey a sense of seriousness, commitment, or official purpose.
This makes it particularly prevalent in:
  • Public Speeches and Presentations: When a speaker addresses a large audience or discusses important topics, -고자 lends gravity to their stated goals. For example, a politician might say, 국민의 삶을 개선하고자 최선을 다하겠습니다 (In order to improve the lives of the citizens, I will do my best.) This implies a strong commitment and official duty.
  • Official Documents and Reports: In formal writing, such as academic papers, government reports, business proposals, or policy statements, -고자 precisely articulates the objectives or motivations. 본 연구는 새로운 이론을 정립하고자 수행되었습니다. (This research was conducted in order to establish a new theory.)
  • Formal Announcements and Declarations: When an organization or an individual makes a significant declaration or announcement, -고자 emphasizes the underlying intent. 회사는 고객 만족을 높이고자 서비스 개선에 투자할 것입니다. (The company will invest in service improvements in order to increase customer satisfaction.)
  • Job Interviews and Professional Correspondence: In professional settings, particularly when expressing one's aspirations or reasons for actions, -고자 conveys professionalism and a serious mindset. A job applicant might state, 귀사의 발전에 기여하고자 지원했습니다. (I applied in order to contribute to your company's development.)
  • Legal and Judicial Contexts: In legal discourse, where precise and unambiguous intention is critical, -고자 can be used to state the purpose of actions or laws. 피고인은 자신의 무죄를 입증하고자 증거를 제출했습니다. (The defendant submitted evidence in order to prove their innocence.)
Choosing -고자 signals that the intention is not merely a fleeting desire but a considered and significant objective. It communicates respect for the context and the audience, establishing a more formal and authoritative relationship. It is an active choice to convey seriousness, particularly when a simpler -(으)려고 or -기 위해서 might seem too casual or less emphatic for the situation at hand.
The decision to use -고자 often reflects a speaker's desire to appear more deliberate, responsible, or dedicated to the stated purpose.

Common Mistakes

Learners often encounter specific pitfalls when attempting to use -고자. Understanding these common errors and the underlying reasons will help you use the pattern correctly and naturally.
  1. 1Incorrect Tense Usage in the Preceding Clause: This is perhaps the most frequent mistake. The -고자 clause never takes any tense markers (e.g., past tense -았/었-, future tense -겠-) before -고자. The tense of the entire sentence is determined by the final verb. This is because -고자 expresses an intention that is always current to the subject's state of mind before the action is taken. An intention cannot exist in the past or future relative to its formation.
  • Incorrect: 저는 한국말을 배웠고자 한국에 갔습니다. (I went to Korea having intended to learn Korean.) – This is grammatically unsound.
  • Correct: 저는 한국말을 배우고자 한국에 갔습니다. (I went to Korea in order to learn Korean.) – The past tense is on the final verb 갔습니다.
  1. 1Subject Mismatch Between Clauses: The subject of the intention (the -고자 clause) must be the same as the subject performing the action (the main clause). -고자 expresses the volition of a single agent. You cannot use it to express that one person did something so that another person would achieve a goal.
  • Incorrect: 저는 동생이 성공하고자 열심히 도왔습니다. (I helped my younger sibling diligently so that my younger sibling would succeed.) – The subject (I) intends to help, but the success (성공하고자) is the younger sibling's goal, not explicitly 's intention for 's action.
  • Correct: 저는 동생을 성공시키고자 열심히 도왔습니다. (I helped my younger sibling diligently in order to make my younger sibling succeed.) – Here, 성공시키고자 (in order to make succeed) reflects the 's direct intention.
  • Correct (alternative using another grammar): 저는 동생이 성공하도록 열심히 도왔습니다. (I helped my younger sibling diligently so that my younger sibling would succeed.) – -도록 is appropriate here for expressing a desired outcome for another party.
  1. 1Inappropriate Use in Casual Settings: Due to its inherent formality, using -고자 in casual conversation, texting, or informal writing sounds highly unnatural, stiff, and even sarcastic. It can make you sound pedantic or overly formal, much like using archaic English phrases in everyday speech.
  • Incorrect: (To a friend) 피자 먹고자 식당에 가자. (Let's go to the restaurant to eat pizza.)
  • Correct: (To a friend) 피자 먹으려고 식당에 가자. (Let's go to the restaurant to eat pizza.)
  • Correct: (To a friend) 피자 먹으러 식당에 가자. (Let's go to the restaurant to eat pizza.)
  1. 1Using with Adjectives: -고자 can only attach to action verbs (동사 - dongsa), not descriptive verbs (형용사 - hyeongyongsa) or 이다/아니다. You cannot intend to be a state or quality. If you want to express an intention related to a state, you must transform the adjective into an action verb using a causative form or -아/어지다.
  • Incorrect: 저는 행복하고자 노력했습니다. (I tried to be happy.)
  • Correct: 저는 행복해지고자 노력했습니다. (I tried to become happy.) – Using -아/어지다 to make it an action verb.
By being mindful of these specific points, learners can avoid common errors and gain confidence in using -고자 appropriately in formal Korean contexts. The key is to always consider the subject's volition, the tense logic, and the overall formality of the situation.

Real Conversations

While -고자 is generally absent from casual spoken Korean, it is very much alive and frequently used in formal discourse, both spoken and written. The term "conversations" here refers to structured, purposeful exchanges or monologues in official capacities. These examples illustrate how native speakers employ -고자 to convey serious intent.

These examples highlight that "real conversations" involving -고자 are typically not casual banter but rather structured communication in high-stakes or formal environments. The use of this pattern underscores the gravity of the speaker's intentions and actions, reinforcing the professional or official nature of the interaction. It’s a tool for conveying seriousness, commitment, and a clear, deliberate purpose.

Contrast with Similar Patterns

Understanding -고자 involves not just knowing how to use it, but also appreciating its nuances by contrasting it with other patterns that express intention or purpose. While some may seem interchangeable at first glance, subtle differences in formality, emphasis, and scope dictate their appropriate usage.

-(으)려고 (eu)ryeogo: The Everyday Intention

- Meaning: "intend to," "in order to," "going to." This is the most common and versatile expression of intention in Korean.

- Formality: Casual to polite (depending on the final ending), suitable for nearly all daily situations.

- Emphasis: Focuses on the speaker's desire or plan without necessarily conveying formality or gravitas.

- Scope: Can be used with both verbs and adjectives (with -아/어지려고). Subject agreement is generally required, but slight variations are possible in informal speech. Can take tense markers before -(으)려고 in some contexts (e.g., 했으려고 is technically possible but less common, usually expressed as ~고 싶었어).

- Example: 커피 마시려고 카페에 갔어요. (I went to the cafe to drink coffee.)

- Contrast with -고자: -(으)려고 is the default. Use -고자 only when you specifically need the formal, weighty nuance. Using -고자 in 커피 마시고자 카페에 갔습니다 would sound stiff and overblown.

-기 위해서 (gi wihaeseo): For the Sake of / In Order to (Objective Focus)

- Meaning: "for the sake of," "in order to," "for the purpose of." Also very formal.

- Formality: Highly formal, often interchangeable with -고자 in written and official contexts.

- Emphasis: Focuses more on the objective or benefit of an action. It can imply that the action is a necessary step towards achieving a larger goal, often for the benefit of someone/something else.

- Scope: Used with verbs. While the subject usually aligns, -기 위해서 can sometimes imply a more external or general purpose. For example, 학생들의 학습 능력을 향상시키기 위해서 새로운 프로그램을 도입했다 (We introduced a new program for the purpose of improving students' learning abilities). The emphasis is on the objective benefit for students.

- Example: 환경 보호를 위해 일회용품 사용을 줄여야 합니다. (We must reduce the use of disposable items for the sake of environmental protection.)

- Contrast with -고자: Both are formal "in order to" expressions. -고자 emphasizes the subject's volitional intent, their personal will or determination. -기 위해서 emphasizes the objective, often external, goal or beneficiary. In many formal sentences, they are interchangeable, but -고자 feels slightly more internal and agent-driven.

-(으)러 (eu)reo: Specifically for Going/Coming to Do Something

- Meaning: "in order to (go/come)," "to." This pattern exclusively pairs with verbs of motion (가다, 오다, 다니다, 돌아오다, etc.).

- Formality: Neutral, used in both casual and formal contexts, as long as a verb of motion follows.

- Emphasis: Simply states the purpose for going or coming somewhere.

- Scope: Highly restricted. Cannot be used with non-motion verbs. The object of -(으)러 is always the destination of the motion verb.

- Example: 책 빌리러 도서관에 가요. (I'm going to the library to borrow books.)

- Contrast with -고자: Completely different scope. -(으)러 is only for motion verbs. -고자 can be used with any action verb and implies a much higher degree of formality and intent.

-도록 (dorok): So That / To the Extent That / Until

- Meaning: "so that," "in order that," "to the extent that," "until." This pattern indicates a desired result or extent of an action.

- Formality: Can be used in both formal and informal contexts, depending on the final verb.

- Emphasis: Focuses on the outcome or degree of an action, or a condition that needs to be met. It is less about the speaker's direct intention and more about achieving a certain state or enabling another action.

- Scope: Can be used when the subject of the main clause is different from the subject of the -도록 clause. 선생님이 학생들이 이해하도록 설명해 주셨어요. (The teacher explained so that the students could understand.) Here, the teacher's action (설명하다) is to achieve the students' understanding (이해하다).

- Example: 모두가 들을 수 있도록 크게 말해주세요. (Please speak loudly so that everyone can hear.)

- Contrast with -고자: -고자 expresses the subject's direct intention for their own action. -도록 often expresses an intention for an outcome that might affect others or an extent to which an action is performed. They are not interchangeable when the subjects differ or when the emphasis is on result/extent rather than direct volition.

| Feature | -고자 | -(으)려고 | -기 위해서 | -(으)러 | -도록 |

| :---------------- | :--------------------------------------- | :--------------------------------------- | :------------------------------------- | :--------------------------------------- | :---------------------------------------- |

| Formality | Highly formal, solemn, official | Casual to polite, everyday | Highly formal, objective | Neutral, for motion verbs | Neutral, result/extent |

| Emphasis | Subject's strong, deliberate volition/intent | Subject's general desire/plan | Objective, benefit, external purpose | Purpose for going/coming | Result, extent, enabling condition |

| Subject Link | Same subject for both clauses | Generally same subject | Often same, but can be external | Same subject (for motion) | Can be different subjects |

| Tense/Adjectives| No tense before, only with action verbs | No tense before, can be with adjectives | No tense before, only with verbs | No tense before, only with motion verbs | No tense before, with verbs/adjectives |\

Quick FAQ

These frequently asked questions address common points of confusion for learners regarding -고자.
Q: Can I use -고자 with adjectives (형용사 - hyeongyongsa)?

No, -고자 can only attach to action verbs (동사 - dongsa). Adjectives describe a state or quality, and you cannot intend to be a state. For instance, you can't say 행복하고자 (to intend to be happy). If you want to express an intention related to becoming a certain state, you must first transform the adjective into an action verb using a pattern like -아/어지다 (to become). So, you would say 행복해지고자 (in order to become happy) or 아름다워지고자 (in order to become beautiful).

Q: Is -고자 하다 a common phrase? What does it mean?

Yes, verb stem + 고자 하다 is a very common and useful structure. It literally means "to intend to do [verb]" or "to be desirous of doing [verb]." It functions as a highly formal way to state one's intentions directly. For example, 말씀드리고자 합니다 (I intend to speak/say) is a polite and formal way to begin a statement, often used in presentations or official meetings. Similarly, 알리고자 합니다 (I intend to inform) clearly states the speaker's formal purpose. The 하다 here is an auxiliary verb, indicating the act of intending.

Q: How formal is -고자 compared to -기 위해서?

Both are highly formal. However, there's a subtle difference in nuance. -고자 tends to emphasize the speaker's personal will and determination to achieve a goal. It feels more agent-driven. -기 위해서 often emphasizes the objective or benefit of the action, sometimes for a broader purpose or for others. In many contexts, they can be interchangeable, especially in formal writing, but if you want to highlight your strong, personal commitment, -고자 might be a slightly better fit.

Q: Can -고자 be used in questions?

It is extremely rare to find -고자 used directly in questions. Since -고자 expresses the speaker's or subject's intention, asking about someone else's intention using this highly formal and declarative form would be awkward. Instead, for formal questions about intention, other patterns like -(으)ㄹ 계획입니까? (Do you plan to...?) or -(으)ㄹ 의향이 있으십니까? (Do you have the intention to...?) would be more appropriate.

Q: What is the etymological origin of -고자? Does it have roots in classical Korean?

-고자 originates from Middle Korean and is a direct descendant of the conjunctive ending -고져 (gojyeo), which served a similar purpose of expressing intention or desire. Its preservation in modern formal Korean highlights its long-standing role in conveying deliberate and respectful intent within the language. This historical continuity contributes to its perceived gravity and formality in contemporary usage. The very fact that it has persisted from older forms of the language reinforces its entrenched place in the more elevated registers of Korean.

Q: Are there any specific verbs that commonly pair with -고자?

While it can pair with any action verb, some common pairings include verbs related to communication, action, and public service: 말씀드리고자 (to speak/say), 알리고자 (to inform), 기여하고자 (to contribute), 해결하고자 (to solve), 노력하고자 (to make an effort), 실현하고자 (to realize/achieve). These verbs often appear in contexts where formal statements of intent are made.
