Explicação 개시하다 in your Level:

At the A1 level, you don't need to use '개시하다' actively in your own speech, as '시작하다' (to start) is much more important. However, you might see '개시' on signs in Korean shops or on websites. If you see a sign that says '세일 개시' (Sale Starts), you should recognize that it means something new is beginning. Think of it as a formal 'Start' button. At this stage, just focus on the fact that '개' (open) + '시' (start) means something is opening for the first time or starting officially. You might hear it in very simple announcements like '공격 개시' (Start attack) in games, which helps you associate it with the beginning of an action. Don't worry about the grammar yet; just recognize the word's appearance in public spaces.

At the A2 level, you should begin to distinguish between '시작하다' and '개시하다.' You should understand that '개시하다' is used for more formal or business-related starts. For example, if you are working in a shop or talking about a company's new service, '개시하다' is the appropriate word. You should also learn the passive form '개시되다' (to be started), which is common in news headlines. A key cultural point for A2 learners is the '첫 개시' (first sale of the day). If you visit a Korean market early in the morning, understanding this word will help you understand the vendors' mindset. You can start using it in simple sentences about business hours or official events, but keep using '시작하다' for your personal life.

By the B1 level, you should be able to use '개시하다' correctly in professional or formal writing, such as emails or reports. You should know that it takes an object (marked with -을/를) and is often used with business-related nouns like '업무' (work), '수사' (investigation), or '공사' (construction). You should also be able to distinguish '개시하다' from its homophone '게시하다' (to post a notice), which is a common source of confusion. At this level, you should understand the nuance that '개시하다' implies a planned or official commencement. If you are describing a project's timeline, using '개시' for the official start date makes your Korean sound much more advanced and precise than just using '시작.'

At the B2 level, you should have a firm grasp of the Hanja roots (開: open, 始: start) and how they influence the word's usage across different domains. You should be comfortable hearing this word in news broadcasts regarding international diplomacy (e.g., 'negotiations commenced') or legal proceedings (e.g., 'the trial commenced'). You should also learn more complex collocations like '효력 개시' (becoming effective) and '운행 개시' (starting operation). At this level, you should be able to explain the difference between '개시하다' and '착수하다' (to set to work), noting that '개시' is more about the point of starting, while '착수' is about the action of starting the work itself. Your usage should reflect a clear understanding of register and tone.

At the C1 level, your understanding of '개시하다' should include its idiomatic and cultural nuances. You should be able to use it in complex sentence structures, such as within relative clauses or as part of formal speeches. You should understand how '개시' functions in the stock market ('장 개시') and in specialized legal contexts. You should also be aware of how the word has evolved historically and how it compares to more archaic or literary terms for 'beginning.' In a business setting, you should be able to lead a meeting and use '개시' to signal transitions between phases of a project. Your ability to switch between '시작,' '개시,' '착수,' and '발족' depending on the exact nuance of the situation should be near-native.

At the C2 level, you should have a masterly command of '개시하다' and its place in the broader Korean lexicon. This includes understanding its use in high-level academic papers, legal statutes, and classical literature. You should be able to discuss the subtle differences between '개시' and other Hanja-based synonyms like '개초(開初)' or '시발(始發)' in specific historical or technical contexts. You should also be able to recognize and use the word in creative writing to set a specific formal or dramatic tone. Your understanding should extend to how '개시' interacts with various honorific levels and how it can be used rhetorically to emphasize the importance of a new beginning. At this stage, the word is not just a vocabulary item but a tool for precise and powerful communication.

개시하다 em 30 segundos

개시하다 is a formal verb meaning 'to start' or 'to commence,' primarily used in business, legal, and official contexts.
It is the standard word for 'opening' a business day or starting the first sale of the day in a shop.
Commonly paired with nouns like 'sale,' 'investigation,' 'service,' and 'operation' to indicate a planned beginning.
It is distinguished from the general '시작하다' by its higher register and association with official or public actions.

The Korean verb 개시하다 (gaesihada) is a sophisticated way to say 'to begin' or 'to start.' While the common word 시작하다 is used in almost every daily situation, 개시하다 carries a more formal, official, or commercial weight. It originates from the Hanja characters 開 (개), meaning 'to open,' and 始 (시), meaning 'to begin.' Therefore, its core essence is about 'opening up the start' of something. You will most frequently encounter this word in business environments, such as when a store opens for the day, or in official administrative contexts, such as the commencement of a legal investigation or a government project. It implies a structured or significant beginning rather than a casual one.

Commercial Context: In the world of retail, this word is used to describe the first sale of the day or the start of a massive seasonal sale event. Shopkeepers might use it to signify they are ready for business.
Official/Legal Context: Government agencies '개시' investigations or public services. It suggests that the proper procedures have been followed to trigger the start of an event.
Military/Strategic Context: In historical dramas or news regarding military exercises, you will hear this word used for the commencement of operations or attacks.

백화점이 오늘부터 정기 세일을 개시했다.

Translation: The department store started its regular sale today.

Using 개시하다 instead of 시작하다 instantly elevates the tone of your speech. For example, if you are presenting a business proposal, saying '프로젝트를 개시하겠습니다' (We will commence the project) sounds much more professional and decisive than '프로젝트를 시작할게요.' It signals to the listener that the action is part of a planned, formal process. However, because of this weight, it is rarely used for personal habits like 'I started exercising' or 'I started reading a book.' In those cases, 시작하다 remains the natural choice. Understanding the boundary between these two words is key to mastering mid-to-high-level Korean register.

검찰은 해당 사건에 대한 수사를 개시하기로 결정했습니다.

Translation: The prosecution decided to initiate an investigation into the case.

Service Activation: When a new subway line or a digital service becomes available for the first time, the term '서비스 개시' is used. It marks the transition from preparation to public availability.

Grammatically, 개시하다 is a transitive verb, meaning it usually takes an object marked by the particles -을/를. The structure is typically [Subject] + [Object] + [개시하다]. Because it is a formal word, it is most often conjugated in the -습니다 (formal polite) or -어/아 (standard polite) styles, and rarely in informal 'banmal' unless in a very specific narrative context. You should also be aware of the passive form, 개시되다, which means 'to be started' or 'to be commenced.' This is used when the focus is on the action or event itself rather than who started it.

공격 개시!

Translation: Commence attack! (Commonly heard in movies or games).

When using 개시하다 in a business context, it often refers to the 'opening' of a business day. In Korea, there is a cultural concept of '첫 개시' (the first sale). Shopkeepers believe that the first customer of the day sets the tone for the rest of the day's business. If someone says, '아직 개시도 못 했어요,' they mean they haven't even made their first sale yet today. This specific nuance is unique to the commercial application of the word and is a great way to sound like a native speaker who understands Korean business culture.

Object Collocations: Common objects include: 사업 (business), 수사 (investigation), 세일 (sale), 서비스 (service), 업무 (work/tasks), and 회담 (talks/negotiations).
Time Indicators: It is often used with specific time markers like '오늘부로' (as of today), '정각에' (at the stroke of the hour), or '즉시' (immediately).

새로운 온라인 뱅킹 서비스가 내일부터 개시됩니다.

Translation: The new online banking service will be initiated starting tomorrow.

In writing, 개시하다 is preferred in reports and news articles. If you are writing a formal email to a client about starting a contract, '계약 이행을 개시하겠습니다' (We will commence the execution of the contract) provides a level of certainty and professionalism. It sounds more binding than using '시작하다.' Furthermore, in legal documents, '효력이 개시되다' is a standard phrase meaning 'to come into effect' or 'for the legal force to begin.' This illustrates how the word bridges the gap between 'starting an action' and 'becoming active/operational.'

You are most likely to hear 개시하다 in environments where formal announcements are made. For instance, at a large conference or a sporting event, the announcer might say, '이제 경기를 개시하겠습니다' (We will now commence the match). It adds a sense of ceremony to the beginning of the event. Similarly, on the news, journalists use it when reporting on high-level government decisions or international relations, such as '양국은 평화 협상을 개시하기로 합의했습니다' (The two countries agreed to initiate peace negotiations).

이번 특판 행사는 오전 9시 정각에 개시될 예정입니다.

Translation: This special sale event is scheduled to commence at exactly 9:00 AM.

Another common place to encounter this word is in the workplace. During a project kickoff meeting, a manager might use the word to signal the official start of a new phase. It’s also prevalent in the tech industry when launching new software or servers. If a system is '개시'ed, it means it is now live and operational. In these settings, the word conveys a sense of readiness and the culmination of preparation efforts. It isn't just about the first step; it's about the official 'go' signal.

Public Transportation: Announcements about new bus routes or subway lines often use '운행 개시' (commencement of operation).
Stock Market: Financial news reports use it to describe the opening of the market (장 개시).

드디어 오늘부터 새로운 지하철 노선이 운행을 개시합니다.

Translation: Finally, the new subway line starts its operation today.

In traditional Korean markets, you might hear older vendors talking about '개시.' They might say '마수걸이 개시했다' which is a very idiomatic way of saying they finally made their first sale. While '마수걸이' is the specific folk term for the first sale, '개시' is the more general term used alongside it. If you visit a market early in the morning, you might hear a vendor happily shouting to their neighbor that they've '개시'ed for the day, which means the day's luck has started flowing.

The most common mistake learners make is using 개시하다 in casual, everyday contexts where it sounds unnaturally stiff. For example, if you say '나는 아침 식사를 개시했다' (I commenced my breakfast), it sounds like you are treating your meal like a formal military operation or a government project. In English, this is like saying 'I initiated the consumption of my morning repast' instead of 'I started eating breakfast.' Always default to 시작하다 for personal actions, hobbies, and informal conversations.

공부를 개시할게요. (X)
공부를 시작할게요. (O)

Correction: Use '시작하다' for personal tasks like studying.

Another mistake is confusing 개시하다 (to start/open) with 게시하다 (to post/display). They sound very similar (Gaesi vs. Gesi), but their meanings are entirely different. 게시하다 (揭示-) is used when you put up a notice on a bulletin board or post something on a website. If you tell someone you '개시'ed a notice, they might think you 'started' the notice process rather than 'posted' it. Pay close attention to the vowel: 'ㅐ' (ae) for starting/opening, and 'ㅔ' (e) for posting.

Spelling Confusion: 개시 (Commencement) vs. 게시 (Posting). Example: 공고를 게시하다 (Post a notice) vs. 공사를 개시하다 (Commence construction).
Register Mismatch: Using it with close friends or family. It makes you sound like a robot or a news anchor.

Finally, some learners forget that 개시하다 requires a certain level of 'publicness' or 'formality.' You wouldn't '개시' a conversation with a friend, but a diplomat might '개시' a dialogue with a foreign counterpart. If the action doesn't have an official start time or a formal procedure, 시작하다 or 말을 걸다 (to strike up a conversation) is more appropriate. Using high-level vocabulary is great, but using it in the wrong register can actually make your Korean sound less natural.

To truly master 개시하다, you need to see where it fits among other Korean words for 'starting.' The most obvious alternative is 시작하다, which is the universal 'to start.' However, there are several other specialized verbs that overlap with 개시하다 depending on the specific context. For example, 착수하다 (着手-) means to 'set to work' or 'embark on' a project or investigation, often implying that you have physically started the labor involved. While 개시하다 is the official announcement of the start, 착수하다 emphasizes the beginning of the actual work process.

시작하다 (To Start): The general term. Used for everything from 'starting a movie' to 'starting a diet.' Less formal than 개시하다.
착수하다 (To Embark/Commence Work): Used for projects, investigations, or construction. It implies 'getting one's hands on' the work.
개막하다 (To Open a Curtain/Event): Specifically used for festivals, plays, or sports seasons. Literally 'to open the curtain.'

정부는 신도시 건설에 착수했다.

Translation: The government embarked on the construction of the new city.

Another interesting comparison is with 발족하다 (發足-), which means 'to start an organization' or 'to launch a committee.' Literally meaning 'to set foot forward,' it is used when a new group is officially formed to perform a specific task. While you might '개시' the first meeting of a committee, the committee itself is '발족'ed. Similarly, 창업하다 is used specifically for starting a business/company. If you open your shop doors for the day, you '개시' business, but when you first founded the company, you '창업'ed.

축제가 화려하게 개막했다.

Translation: The festival opened (commenced) magnificently.

How Formal Is It?

Curiosidade

In traditional markets, the 'first sale' (개시) was so important that if the first customer was rude, the merchant might close for the day, fearing bad luck!

Sino-Korean (Hanja-derived vocabulary).
