Noun + 까지

Overview

Korean is a language that extensively uses particles—small grammatical markers that attach to nouns, pronouns, and sometimes other parts of speech to define their function in a sentence. Among these, the particle 까지 (kkaji) is fundamental for clearly marking an endpoint or limit. This single particle effectively conveys the meanings of "until," "by," and "to" in English, depending on whether it applies to time or location.

Mastering 까지 provides you with a crucial tool for precisely expressing deadlines, durations, and destinations in Korean. It functions as a definitive boundary marker, signaling the cessation of an action, the conclusion of a journey, or the maximum extent of something.

How This Grammar Works

The particle 까지 operates as a bound noun suffix, meaning it attaches directly to a noun without any intervening space. This grammatical behavior is characteristic of most Korean particles, which serve to establish the relationship between the noun they modify and the rest of the sentence. A significant advantage for learners is that 까지 is invariable: its form remains constant regardless of whether the preceding noun ends in a vowel or a consonant.
This simplifies its application considerably.
At its core, 까지 signifies a limit or extent. This limit can be temporal, specifying the final point in time ("until," "by"), or spatial, indicating the final destination or physical reach ("to," "as far as"). The underlying linguistic principle is that 까지 functions as a terminal marker, explicitly signaling the culmination or boundary of a process, action, or state.
When you use 까지, you are emphatically drawing a line, indicating that something either continues up to that point, must be accomplished by that point, or physically extends to that point. For instance, in 부산까지 가요 (busankkaji gayo, "I'm going to Busan"), 까지 emphasizes reaching Busan as the definitive end of the journey, highlighting the full scope of the movement rather than just a general direction. This emphasis on the boundary is crucial for differentiating 까지 from other particles like 에.

Formation Pattern

1
The formation of 까지 is one of the simplest grammatical rules you'll encounter in Korean. It has no conjugations or form changes whatsoever. The rule is always straightforward:
2
Noun + 까지
3
You simply take any noun—be it a place, a specific time, or a general concept—and attach 까지 directly to its end. You do not need to consider whether the noun ends in a vowel or a consonant, as its form never alters. This consistency makes 까지 particularly easy to integrate into your sentences from day one.
4
Key Principle: Korean particles are bound morphemes and always attach directly to the word they modify. This means there should be absolutely no space between the noun and 까지. Incorrect spacing is a very common beginner mistake that can disrupt sentence flow and clarity. For example, 집 까지 (incorrect) should always be written as 집까지 (jippkkaji).
5
Here’s a table demonstrating this simple pattern:
6
| Noun | Meaning | Noun + 까지 | Meaning |
7
| :---------- | :---------- | :------------------ | :--------------------------- |
8
| 학교 (hakgyo) | School | 학교까지 (hakgyokkaji) | To school / As far as school |
9
| 내일 (nae-il) | Tomorrow | 내일까지 (nae-ilkkaji) | Until tomorrow / By tomorrow |
10
| 지하철역 (jihacheollyeok) | Subway station | 지하철역까지 (jihacheollyeokkkaji) | To the subway station |
11
| 세 시 (se si) | Three o'clock | 세 시까지 (se sikka ji) | Until three o'clock / By three o'clock |

When To Use It

The versatility of 까지 allows it to function in several distinct contexts, primarily related to time and location, but also extending to emphasize broader extent or inclusion. Understanding these specific applications is key to its correct use.
1. Marking a Spatial Endpoint: "To," "As Far As"
When 까지 is attached to a location noun, it indicates the final destination of movement or the extent of a physical reach. Unlike 에, which neutrally marks a destination, 까지 often implies covering a distance or reaching a specific boundary. It emphasizes the journey up to that point, highlighting the completion of the movement to that particular limit.
  • 저 서울역까지 걸어갔어요. (jeo seoullyeokkkaji georeogasseoyo) / 저는 서울역까지 걸어갔습니다. (jeoneun seoullyeokkkaji georeogasseumnida)
  • I walked all the way to Seoul Station. (Implies a significant distance covered, emphasizing the completion of the journey.)
  • 버스 정류장까지 뛰어갔어. (beoseu jeongnyujangkkaji ttwieogasseo) / 버스 정류장까지 뛰어갔습니다. (beoseu jeongnyujangkkaji ttwieogasseumnida)
  • I ran to the bus stop. (Emphasizes the entire dash, ending precisely at the stop.)
  • 택시로 공항까지 갈 거예요. (taeksireo gonghangkkaji gal geoyeyo) / 택시로 공항까지 갈 것입니다. (taeksireo gonghangkkaji gal geosimnida)
  • I will go to the airport by taxi. (Commonly used when giving directions or specifying the extent of travel.)
In practical scenarios, like instructing a taxi driver, 까지 is almost always preferred because it specifies the full extent of the requested journey, ensuring the driver understands the exact destination as the final point of travel. For example, 강남역까지 가 주세요. (gangnamyeokkkaji ga juseyo, "Please go to Gangnam Station.")
2. Marking a Temporal Endpoint for Continuous Actions: "Until"
When 까지 is attached to a time noun, it signifies the end point of an ongoing action or state. The action continues up to, but not beyond, the specified time. This usage is equivalent to the English "until." The verb typically describes an activity that unfolds continuously over a duration.
  • 밤 10시까지 공부했어요. (bam yeolsikaji gongbuhaesseoyo) / 밤 10시까지 공부했습니다. (bam yeolsikaji gongbuhaetseumnida)
  • I studied until 10 PM. (The studying was a continuous activity that ceased at 10 PM.)
  • 점심시간까지 회의가 계속될 거야. (jeomsim sigankkaji hoe-uiga gyesokdoel geoya) / 점심시간까지 회의가 계속될 겁니다. (jeomsim sigankkaji hoe-uiga gyesokdoel geomnida)
  • The meeting will continue until lunchtime. (The meeting is an ongoing event with its conclusion marked by lunchtime.)
  • 오후 5시까지 여기에 있을게. (ohu daseot sikaji yeogie isseulge) / 오후 5시까지 여기에 있겠습니다. (ohu daseot sikaji yeogie itgesseumnida)
  • I will be here until 5 PM. (My presence is continuous and concludes at 5 PM.)
3. Marking a Temporal Endpoint for Completion: "By" (Deadline)
까지 also functions to indicate a deadline, meaning an action must be completed at or before the specified time. This usage aligns with the English "by." The context of the sentence, particularly the nature of the verb, usually clarifies whether it means "until" (continuous) or "by" (deadline). Verbs describing completion or punctual actions often imply a deadline.
  • 내일까지 숙제를 제출하세요. (nae-ilkkaji sukjereul jechulhaseyo) / 내일까지 숙제를 제출하십시오. (nae-ilkkaji sukjereul jechulhasipsio)
  • Please submit your homework by tomorrow. (The submission must occur at any point up to and including tomorrow.)
  • 금요일까지 보고서를 완성해야 해. (geumyo-ilkkaji bogoseoreul wansonghaeya hae) / 금요일까지 보고서를 완성해야 합니다. (geumyo-ilkkaji bogoseoreul wansonghaeya hamnida)
  • You must complete the report by Friday. (Completion is required on or before Friday.)
  • 점심시간까지 이메일 보내 줘. (jeomsim sigankkaji imeil bonae jwo) / 점심시간까지 이메일을 보내 주십시오. (jeomsim sigankkaji imeil-eul bonae jusipsio)
  • Please send the email by lunchtime. (The email needs to be sent sometime before or at lunchtime.)
4. Indicating Range (Paired with 부터 or 에서)
까지 frequently appears in conjunction with other particles to specify a range or extent, often translating to "from... to..." or "from... until...". This construction clearly defines both the starting and ending boundaries.
  • Time Range (부터...까지): 부터 (buteo) marks the temporal starting point.
  • 아침 9시부터 저녁 6시까지 일해요. (achim ahopeusibuteo jeonyeok yeoseot sikaji ilhaeyo) / 아침 9시부터 저녁 6시까지 일합니다. (achim ahopeusibuteo jeonyeok yeoseot sikaji ilhamnida)
  • I work from 9 AM until 6 PM.
  • 월요일부터 금요일까지 수업이 있어. (woryo-ilbuteo geumyo-ilkkaji sueop-i isseo) / 월요일부터 금요일까지 수업이 있습니다. (woryo-ilbuteo geumyo-ilkkaji sueop-i itseumnida)
  • There are classes from Monday until Friday.
  • Location Range (에서...까지): 에서 (eseo) marks the spatial starting point.
  • 집에서 회사까지 버스로 30분 걸려. (jibeseo hoesakkaji beoseuro samsipbun geollyeo) / 집에서 회사까지 버스로 30분 걸립니다. (jibeseo hoesakkaji beoseuro samsipbun geollimnida)
  • It takes 30 minutes from home to the company by bus.
  • 여기에서 부산까지 얼마나 걸려요? (yeogieoseo busankkaji eolmana geollyeoyo?) / 여기에서 부산까지 얼마나 걸립니까? (yeogieoseo busankkaji eolmana geollimnikka?)
  • How long does it take from here to Busan?
5. Emphasizing Extent or Inclusion: "Even," "Up To"
In specific contexts, 까지 can carry an emphatic nuance of "even," "up to," or "including." This usage highlights that something extends to an unexpected degree or includes an unexpected element. It often implies a sense of a limit being pushed or a boundary being reached, frequently with an element of surprise or noteworthy inclusion.
  • 너까지 왜 그래? (neokkaji wae geurae?)
  • Even you, why are you being like this? (Implies surprise that you are also involved or acting a certain way, suggesting a boundary of acceptable behavior has been crossed.)
  • 아이들까지 모두 참여했어. (aideulkkaji modu chamyeohaesseo) / 아이들까지 모두 참여했습니다. (aideulkkaji modu chamyeohaetseumnida)
  • Even the children participated. / Up to and including the children, everyone participated. (Emphasizes broad inclusion, extending to those not typically expected to participate.)
  • 새벽까지 잠 못 잤어. (saebyeokkkaji jam mot jasseo) / 새벽까지 잠을 못 잤습니다. (saebyeokkkaji jam-eul mot jatseumnida)
  • I couldn't sleep even until dawn. (The 까지 adds a subtle emphasis on the late, challenging hour the sleeplessness extended to.)
This nuanced usage stems directly from 까지's core concept of marking a boundary, but applies it to the scope of participation or the extremity of a situation rather than just time or space.

When Not To Use It

Understanding when not to use 까지 is just as important as knowing its correct applications, as misuse can lead to awkward or incorrect sentences. Its precise function as a boundary marker for time and place means it is not interchangeable with particles that serve other purposes.
1. For Recipients of an Action: Use 에게, 한테, 께
까지 is specifically for marking the endpoint of movement or time, not for indicating the recipient of an action (e.g., giving, sending, telling). When you are performing an action to or for a person, you must use a different set of particles. This is a common English-to-Korean transfer error.
  • Incorrect: 친구까지 선물을 줬어요. (chingu-kkaji seonmul-eul jwosseoyo)
  • (Intended: I gave a gift to my friend.) — This incorrectly implies "Even my friend received a gift," using the emphatic nuance of 까지.
  • Correct: 친구에게 선물을 줬어요. (chingu-ege seonmul-eul jwosseoyo) / 친구한테 선물을 줬어. (chingu-hante seonmul-eul jwosseo)
  • I gave a gift to my friend.
  • Correct (honorific): 선생님께 말씀드렸습니다. (seonsaengnim-kke malsseumdeuryeotseumnida)
  • I spoke to the teacher.
Always use 에게, 한테, or the honorific 께 when the English "to" signifies a recipient of an action, not 까지.
2. For Simple Destination without Emphasis on Extent: Use 에
While 까지 can mark a destination, 에 is the more neutral particle for simply indicating where an action occurs or where something is going, without the inherent emphasis on covering distance or reaching a specific limit. If the nuance of "as far as" or "all the way to" is not intended, 에 is often more natural for basic destination marking, particularly with verbs of going or coming (가다, 오다).
  • Less natural (unless emphasizing the journey): 학교까지 가요. (hakgyokkaji gayo)
  • I go as far as school. (This implies a journey, not just a simple destination.)
  • More natural (simple destination): 학교에 가요. (hakgyoe gayo)
  • I go to school. (A straightforward statement of destination.)
The difference is subtle, but 까지 adds a layer of completion or full extent to the movement that 에 does not inherently possess. When you don't need to stress the boundary, 에 is the default choice.
3. For Duration: Use 동안
까지 marks the end of a time period, not the length of the period itself. When you want to express "for (a duration)," you must use 동안 (dong-an). Confusing these two is a common mistake that fundamentally changes the meaning of your sentence.
  • Incorrect: 두 시간까지 기다렸어요. (du sigankkaji gidaryeosseoyo)
  • (Intended: I waited for two hours.) — This means "I waited until two o'clock," if 두 시 were a point in time, or is grammatically awkward if 두 시간 is interpreted as a duration. 까지 here marks an end point, not a span.
  • Correct: 두 시간 동안 기다렸어요. (du sigan dong-an gidaryeosseoyo) / 두 시간 동안 기다렸습니다. (du sigan dong-an gidaryeotseumnida)
  • I waited for two hours.
The distinction is critical: 까지 is a boundary marker (when something ends); 동안 is a duration marker (how long something lasts).

Common Mistakes

Learners frequently encounter specific pitfalls when using 까지. Recognizing these common error patterns and understanding their underlying causes can significantly accelerate your mastery and prevent misunderstandings.
1. Incorrect Spacing Between Noun and 까지:
One of the most persistent errors for new learners is separating 까지 from the noun it modifies. Korean particles are clitics; they attach directly to the preceding word, forming a single phonological and grammatical unit. This is a fundamental rule for all Korean particles.
  • Incorrect: 회사 까지 (hoesa kkaji)
  • Correct: 회사까지 (hoesakkaji)
  • Rule: Always attach 까지 directly to the noun without any intervening space. Think of it as part of the noun itself when considering spelling and pronunciation. A space fundamentally alters the grammatical structure, often making the particle appear as a separate word, which is grammatically incorrect.
2. Using 에서 for the Starting Point of Time:
에서 is correctly used to mark a starting point for location (집에서 - from home, 서울에서 - from Seoul). However, for the starting point of time, the particle 부터 (buteo) must be used. This distinction is critical for clearly expressing temporal ranges.
  • Incorrect: 월요일에서 금요일까지 일해요. (woryo-il-eseo geumyo-ilkkaji ilhaeyo)
  • (Intended: I work from Monday to Friday.) — This is grammatically incorrect because 에서 cannot mark a temporal origin.
  • Correct: 월요일부터 금요일까지 일해요. (woryo-ilbuteo geumyo-ilkkaji ilhaeyo) / 월요일부터 금요일까지 일합니다. (woryo-ilbuteo geumyo-ilkkaji ilhamnida)
  • I work from Monday to Friday.
  • Rule: Remember the distinct pairings: 에서...까지 for spatial ranges (places), and 부터...까지 for temporal ranges (times).
3. Confusing "To" (Destination/Extent) with "To" (Recipient):
As discussed in "When Not To Use It," 까지 should not be used when the English "to" means "to a person" as a recipient of an action like giving, telling, or sending. This is a common direct translation error from English, where "to" can be highly versatile. Korean uses specific particles to differentiate these meanings.
  • Incorrect: 선생님까지 질문했어요. (seonsaengnimkkaji jilmunhaesseoyo)
  • (Intended: I asked a question to the teacher.) — This sentence implies either "Even the teacher asked a question" or "I asked questions up to the teacher (i.e., including the teacher in my questioning range)," not that the teacher was the recipient of your question.
  • Correct: 선생님께 질문했어요. (seonsaengnimkke jilmunhaesseoyo) / 선생님한테 질문했어. (seonsaengnimhante jilmunhaesseo)
  • I asked a question to the teacher.
  • Rule: Use 에게, 한테, or the honorific 께 for human recipients. 까지 marks spatial or temporal limits, not personal targets of action.
4. Misunderstanding the "Until" vs. "By" Nuance:
While 까지 covers both "until" (continuous action) and "by" (deadline) in Korean, English speakers sometimes struggle to correctly infer which meaning is intended in Korean sentences without explicit context. This can lead to ambiguity or misinterpretation if the verb's nature isn't considered.
  • 오후 6시까지 기다릴게요. (ohu yeoseot sikaji gidarilgeyo)
  • This usually means "I will wait until 6 PM" (continuous action, implied by 기다리다 - to wait).
  • 오후 6시까지 제출해 주세요. (ohu yeoseot sikaji jechulhae juseyo)
  • This clearly means "Please submit it by 6 PM" (deadline for completion, implied by 제출하다 - to submit).
  • Rule: Pay close attention to the verb and overall context. Verbs of duration or continuous action (e.g., 기다리다 - to wait, 공부하다 - to study, 있다 - to be/stay) tend to imply "until." Verbs of completion or punctual action (e.g., 제출하다 - to submit, 끝내다 - to finish, 오다 - to come, 가다 - to go) tend to imply "by" when paired with a future time. If the context is ambiguous, adding clarifying phrases or being more explicit with the verb choice can help.

Common Collocations

Certain phrases and expressions frequently feature 까지, becoming almost idiomatic. Memorizing these as units will enhance your fluency and comprehension, as they are integral parts of everyday Korean communication.
  • 언제까지 (eonjekkaji): Until when? / By when? / How long?
  • This interrogative phrase asks for a temporal endpoint. It is highly versatile for inquiring about deadlines or durations.
  • 언제까지 기다려야 해요? (eonjekkaji gidaryeoya haeyo?) / 언제까지 기다려야 합니까? (eonjekkaji gidaryeoya hamnikka?)
  • How long do I have to wait? (Until when should I wait?)
  • 지금까지 (jigeumkkaji): Until now / So far / Up to the present
  • Indicates the duration or extent from an unspecified past point up to the current moment. It implies a continuous state or action leading to the present.
  • 지금까지 잘 지내셨어요? (jigeumkkaji jal jinaesyeosseoyo?) - Have you been well until now? (A common polite greeting.)
  • 여기까지 (yeogikkaji): Up to here / This far / Until this point
  • Used for both physical location and metaphorical extent (e.g., a conversation, a task). It marks a definitive stopping point.
  • 책을 여기까지 읽었어요. (chaegeul yeogikkaji ilgeosseoyo) / 책을 여기까지 읽었습니다. (chaegeul yeogikkaji ilgeotseumnida)
  • I read the book up to here.
  • 끝까지 (kkeutkkaji): Until the end / To the very end
  • Emphasizes persistence or completion through an entire process, often in the face of difficulty. It conveys a strong sense of commitment.
  • 끝까지 포기하지 마세요! (kkeutkkaji pogihaji maseyo!) / 끝까지 포기하지 마십시오! (kkeutkkaji pogihaji masipsio!)
  • Don't give up until the end!

Contrast With Similar Patterns

Differentiating 까지 from other seemingly similar Korean particles is vital for precise expression and avoiding common grammatical errors. Learners often confuse it with 에 for location and 동안 for time, as well as the English usage of "until" and "by."
1. 까지 vs. 에 (Location)
Both particles can indicate a destination, but their nuances differ significantly, reflecting different focuses on the movement or state.
  • 에 (e): Marks a static location or a simple destination. It indicates where something is, where something is going, or where an action takes place, without inherent emphasis on the journey or the boundary reached. It's a neutral marker for existence, arrival, or departure at a place.
  • 학교에 가요. (hakgyoe gayo) - I go to school. (Simple statement of destination, no emphasis on the path or effort.)
  • 집에 있어요. (jibe isseoyo) - I am at home. (Static location of existence.)
  • 도서관에 책이 많아요. (doseogwane chaegi manayo) - There are many books at the library. (Location of existence for books.)
  • 까지 (kkaji): Emphasizes the endpoint of a movement or the extent of a journey, implying that the entire distance up to that point is covered or that a boundary is reached. It draws attention to the completion of the travel or the physical reach, often carrying a nuance of effort or scope.
  • 학교까지 걸어갔어요. (hakgyokkaji georeogasseoyo) - I walked to school (implying the whole distance was covered, possibly a long walk). The focus is on the journey's completion at school.
  • 여기까지 오세요. (yeogikkaji oseyo) - Please come up to here. (Emphasizes the specific boundary that should not be crossed, a clear limit.)
  • 이 길은 산 정상까지 이어져요. (i gireun san jeongsangkkaji ieojeoyo) - This road extends up to the mountain peak. (Describes the full extent of the road.)
Key takeaway: If you are simply stating a destination without any special emphasis on the journey, effort, or reach, 에 is often sufficient and more common. If you want to highlight the completion of a movement, specify a clear boundary, or emphasize the full scope of travel, 까지 is the appropriate choice. In practical scenarios like giving taxi directions, 까지 is preferred because it unambiguously defines the endpoint of the paid journey.
2. 까지 vs. 동안 (Time)
These two particles both relate to time but serve fundamentally different functions. Confusing them is a common error that alters the temporal meaning of a sentence.
  • 까지 (kkaji): Marks the terminal point of a period of time. It tells you when something ends or by when something must be done. It answers the question "Until when?" or "By when?".
  • 밤 12시까지 일했어요. (bam yeoldusikaji ilhaesseoyo) - I worked until 12 AM. (Endpoint of working; the continuous action stopped at midnight.)
  • 내일까지 숙제를 끝내야 해요. (nae-ilkkaji sukjereul kkeunnaeya haeyo) - I have to finish homework by tomorrow. (Deadline for completion; the action must be done at or before tomorrow.)
  • 동안 (dong-an): Indicates the duration or length of time for which an action or state continues. It answers the question "How long?". 동안 specifies the span of time, not its end point.
  • 세 시간 동안 일했어요. (se sigan dong-an ilhaesseoyo) - I worked for three hours. (Duration of working; the length of time spent working.)
  • 방학 동안 여행했어요. (banghak dong-an yeohaenghaesseoyo) - I traveled during the vacation. (Period over which the travel occurred, specifying the span of the vacation.)
Key takeaway: 까지 specifies when something stops or is due; 동안 specifies how long something lasts. Do not use 까지 when you intend to express "for a duration." For example, 두 시간 동안 기다렸어요 (I waited for two hours) is correct, while 두 시간까지 기다렸어요 would incorrectly imply "I waited until two o'clock" if 두 시간 was misunderstood as a point in time, or would be ungrammatical if 두 시간 is intended as a duration.
3. English "Until" vs. "By" (Korean 까지 handles both)
This is a frequent source of confusion for English speakers because Korean uses a single particle, 까지, for two concepts that are distinct in English. The nuance of continuity versus completion is usually inferred from the verb.
  • English "Until": Implies a continuous action that stops at a certain point. The action spans from a start point up to the end point.
  • "I will wait until 5 PM."
  • English "By": Implies an action that must be completed at or before a certain point (a deadline). The action is expected to be finished by the time limit, not necessarily continuously performed until then.
  • "Please finish the report by Friday."
In Korean, 까지 can convey both meanings. The specific interpretation is largely determined by the verb used and the context of the sentence. Learners must develop an intuition for this interaction.
  • 5시까지 기다릴게요. (daseot sikaji gidarilgeyo) - I will wait until 5 PM. (The verb 기다리다 (to wait) describes a continuous action, naturally implying "until.")
  • 금요일까지 보고서를 제출하세요. (geumyo-ilkkaji bogoseoreul jechulhaseyo) - Please submit the report by Friday. (The verb 제출하다 (to submit) describes a punctual, completing action, naturally implying a deadline, or "by.")
Cultural Insight: The flexibility of 까지 to encompass both "until" and "by" reflects a linguistic efficiency where the temporal boundary itself is the primary grammatical concern. The nature of the action (continuous vs. punctual) provides the secondary contextual cue, which Korean speakers intuitively grasp.
This requires learners to develop an intuitive understanding of how different verbs interact with 까지.

Quick FAQ

Addressing common questions helps consolidate understanding and clarify lingering doubts, ensuring a comprehensive grasp of 까지.
Q: Can 까지 be used with people?

Yes, but its meaning changes significantly. When 까지 is used with a person, it often carries the nuance of "even" or "up to (and including) that person," implying an unexpected extent or inclusion. This is an advanced nuance distinct from marking a destination or recipient.

  • 선생님까지 화를 내셨어요. (seonsaengnimkkaji hwareul naesyeosseoyo) - Even the teacher got angry. (Implies surprise that the teacher, who might usually be calm, also showed anger.)
However, for physical movement to a person (e.g., "go to my friend"), or for indicating a recipient of an action (e.g., "give to my friend"), you must use 에게 (ege), 한테 (hante), or the honorific 께 (kke). For instance, you don't say 친구까지 가요 (chingu-kkaji gayo) to mean "I go to my friend"; you would say 친구에게 가요 (chingu-ege gayo) or 친구한테 가요.
Q: Is 까지 formal or informal?

까지 itself is a neutral particle and carries no inherent level of formality or politeness. The formality of the sentence is determined entirely by the verb ending used at the end of the clause or sentence. Korean politeness is primarily conveyed through these verb conjugations.

  • 점심시간까지 기다려요. (jeomsim sigankkaji gidaryeoyo) - I wait until lunchtime. (Polite casual - 아요/어요 ending)
  • 점심시간까지 기다립니다. (jeomsim sigankkaji gidarimnida) - I wait until lunchtime. (Formal polite - ㅂ니다/습니다 ending, often used in public speaking or formal writing)
  • 점심시간까지 기다려. (jeomsim sigankkaji gidaryeo) - Wait until lunchtime. (Intimate casual - 아/어 ending, used with close friends or subordinates)
Q: Can I drop 부터 (from) and just use 까지 (to/until)?

Absolutely. While 부터...까지 provides a complete range (from A to B), it is very common and natural to use 까지 alone, especially when the starting point is obvious, irrelevant, or already understood from context. You don't always need to explicitly state the origin if the focus is solely on the endpoint.

  • 새벽 3시까지 영화를 봤어요. (saebyeok sesikaji yeonghwaleul bwasseoyo) / 새벽 3시까지 영화를 봤습니다. (saebyeok sesikaji yeonghwaleul batseumnida)
  • I watched a movie until 3 AM. (The starting time of the movie is not crucial to the statement.)
  • 이 길은 저기까지 연결돼요. (i gireun jeogikkaji yeongyeoldoeyo) / 이 길은 저기까지 연결됩니다. (i gireun jeogikkaji yeongyeoldwimnida)
  • This road connects to over there. (The starting point of the road is implied to be "here" or understood.)
Q: What about 까지도?

까지도 is formed by adding the emphatic particle 도 (do, meaning "also" or "even") to 까지. This construction adds an extra layer of emphasis, highlighting the extreme or unexpected nature of the limit or inclusion. It conveys a stronger sense of "even until," "even to," or "up to and including." It is used when you want to express a degree of surprise, extremity, or a boundary that is particularly notable.

  • 아이들까지도 그 소식에 놀랐어요. (aideulkkajido geu sosige nollasseoyo) - Even the children were surprised by the news. (Stronger emphasis than 아이들까지, highlighting the unexpectedness of children's reaction.)
  • 새벽까지도 잠 못 잤어. (saebyeokkkajido jam mot jasseo) - I couldn't sleep even until dawn. (Emphasizes the severity of the sleeplessness extending to such a late and inconvenient hour.)
Use 까지도 when you want to explicitly highlight the "even" aspect of the limit, drawing attention to a noteworthy extent or inclusion.

By vs. Until

In English, 'Finish by 2pm' and 'Wait until 2pm' are different. In Korean, both are 2시까지. The verb tells the story!
💬

The Taxi Rule

When telling a taxi driver where to go, [Place]까지 가 주세요 is the most standard, polite phrasing.
⚠️

Don't use with people (usually)

Don't say 친구까지 선물 줬어 for 'I gave a gift to a friend.' That implies 'I gave a gift *even* to my friend.' Use 한테/에게 for recipients.
🎯

The 'Even' Nuance

If you hear 너까지, it implies frustration. 'Even you (are doing this)?' It marks the limit of your patience!

Smart Tips

Always check if you mean a point (까지) or a duration (동안).

2시간까지 기다렸어요. → 2시간 동안 기다렸어요.

Use [Location] + 까지 to be clear.

강남역 가요. → 강남역까지 가주세요.

Replace the object marker with 까지.

이름을까지 알아요. → 이름까지 알아요.

Use 어디까지 to ask for extent.
