kansei suru

Explanation at your level:

Hello! Today we learn 完成する (kansei suru). It means 'to finish'. Like when you finish your drawing. You draw a picture, and then you finish it. That is 完成する. Or when you finish eating your food. Yum! You finish it. So, 完成する is for when something is all done. You can say, 'I finish my book.' (本を完成する - hon o kansei suru). Good job!

Let's talk about 完成する (kansei suru), which means 'to complete' or 'to finish'. Imagine you have a project, like building a model airplane. When you put the last piece on and it looks great, you have 完成するd it! It's used when something is brought to its final state. For example, 'We will complete the report by Friday.' (金曜日までにレポートを完成します - Kin'yōbi made ni repōto o kansei shimasu). It’s a useful verb for talking about tasks that are done.

The Japanese verb 完成する (kansei suru) means 'to complete' or 'to finish', often implying a successful end to a task or project. It's more than just 'to end'; it suggests reaching a final, often satisfactory, state. For instance, 'After months of hard work, the architect finally completed the design.' (何ヶ月もの努力の後、建築家はついにデザインを完成しました - Nankagetsu mo no doryoku no ato, kenchikuka wa tsuini dezain o kansei shimashita). You can use it for anything from homework to building a house, emphasizing the accomplishment of finishing.

完成する (kansei suru) is a versatile Japanese verb meaning 'to complete' or 'to bring to fruition.' It carries a nuance of achieving a desired end state, often with a sense of quality or finality. It's used for a wide range of activities, from artistic endeavors to large-scale construction. For example, 'The team aims to complete the new software by the end of the year.' (チームは年末までに新しいソフトウェアを完成させることを目指しています - Chīmu wa nenmatsu made ni atarashii sofutowea o kansei saseru koto o mezashite imasu). Note the causative form kansei saseru (to make complete) which is also common in professional contexts.

In Japanese, 完成する (kansei suru) signifies the act of bringing something to its ultimate state of completion, often implying a standard of excellence or finality. It transcends simple 'finishing' (終わる - owaru) by suggesting the achievement of a goal or the realization of a plan. Consider its use in contexts like 'The artist spent years perfecting the sculpture, finally completing it to his satisfaction.' (芸術家は何年もかけて彫刻を完成させ、最終的に満足のいくものにしました - Geijutsuka wa nan'nen mo kakete chōkoku o kansei sase, saishūteki ni manzoku no iku mono ni shimashita). The verb often implies a process that has reached its intended, often high-quality, conclusion.

Mastering 完成する (kansei suru) involves understanding its deep connotations of achievement and finality. Beyond mere task completion, it suggests the realization of potential or the attainment of a perfected state. Etymologically linked to characters signifying 'completeness' and 'success,' its usage often implies a benchmark has been met. For instance, 'The historical restoration project was meticulously planned and flawlessly completed, preserving the original structure.' (その歴史的建造物の修復プロジェクトは綿密に計画され、完璧に完成し、元の構造を保存しました - Sono rekishiteki kenzōbutsu no shūfuku purojekuto wa men'mitsuni keikaku sare, kanpeki ni kansei shi, moto no kōzō o hozon shimashita). Its application can range from the tangible (a building) to the abstract (a theory), always pointing towards a definitive and often high-standard conclusion.

  • Means 'to complete' or 'to finish'.
  • Implies achievement, quality, and finality.
  • Used for tasks, projects, creations, and goals.
  • A する-verb, easy to conjugate.

Hey there! Let's dive into the awesome Japanese verb 完成する (kansei suru). It's a super useful word that basically means 'to complete' or 'to finish'. Think about finishing your homework, completing a project at work, or even seeing a building project reach its final stage – that's all 完成する!

It's not just about stopping an action; it's about bringing something to a state where it's done, perfect, or exactly as intended. When you 完成する something, you've achieved a goal and reached the end point successfully. It carries a sense of accomplishment and finality.

We use it in all sorts of situations, from everyday tasks to big professional achievements. Understanding 完成する will definitely boost your Japanese vocabulary and help you talk about progress and success!

The word 完成する (kansei suru) comes to us from Chinese characters, which is super common in Japanese! The characters are 完 (kan) and 成 (sei). 完 (kan) often means 'complete,' 'end,' or 'finish,' while 成 (sei) means 'to become,' 'to succeed,' or 'to accomplish.' Put them together, and you get the idea of 'completing and succeeding' or 'becoming complete.'

Historically, these characters were adopted into Japanese, and the compound word 完成 (kansei) became the noun form, meaning 'completion' or 'perfection.' Adding the verb する (suru), meaning 'to do,' turns it into the verb 完成する. This process of combining Sino-Japanese vocabulary (words derived from Chinese) is a major part of how the Japanese language developed its rich vocabulary, especially for abstract concepts and technical terms.

Think about how English borrows words from Latin or Greek! It's a similar phenomenon. The concept of 'completion' is universal, but the way it's expressed through these characters gives it a specific nuance in Japanese, often implying a high standard of achievement.

So, when do we whip out 完成する (kansei suru)? It's perfect for talking about any kind of task or project that has reached its end. You can use it for homework (宿題を完成する - shukudai o kansei suru), a report (レポートを完成する - repōto o kansei suru), or even a piece of art (絵を完成する - e o kansei suru).

It's also used for larger, more significant achievements, like constructing a building (建物を完成する - tatemono o kansei suru) or developing a new product (新製品を完成する - shinseihin o kansei suru). The key is that something has moved from an unfinished state to a finished one, often with a sense of quality or finality.

Formally, it's quite standard. You'd use it in business meetings, academic writing, or when discussing serious projects. In casual conversation, people might sometimes use simpler verbs like 'する' (suru - to do) or '終わる' (owaru - to end), but 完成する adds a touch of emphasis on the completeness and quality of the finished product. It's a versatile verb that bridges formal and semi-formal contexts nicely!

While 完成する (kansei suru) itself is a standard verb, it appears in phrases that highlight the process or state of completion. Here are a few related ideas:

  • 完璧な完成 (kanpeki na kansei): This means 'perfect completion.' It emphasizes that not only is something finished, but it's done flawlessly. For example, 彼の仕事は完璧な完成だった (Kare no shigoto wa kanpeki na kansei datta) - His work was a perfect completion.
  • 未完成 (mikansei): This is the opposite, meaning 'incomplete' or 'unfinished.' It's a very common prefix. この計画はまだ未完成です (Kono keikaku wa mada mikansei desu) - This plan is still incomplete.
  • 完成品 (kanseihin): This refers to a 'finished product' or 'completed article.' It's the result of the verb's action. これは試作品ではなく、完成品です (Kore wa shisaku hin de wa naku, kanseihin desu) - This is not a prototype, but a finished product.
  • 完成度 (kansei-do): This means 'degree of completion' or 'level of perfection.' It's often used to evaluate how finished something is. このゲームの完成度が高い (Kono gēmu no kansei-do ga takai) - The completion level of this game is high.
  • 完成を祝う (kansei o iwau): This means 'to celebrate the completion.' It's used for significant achievements. 新しい橋の完成を祝いました (Atarashii hashi no kansei o iwa imashita) - We celebrated the completion of the new bridge.

These expressions help paint a fuller picture of what 'completion' means in different contexts!

Let's break down the grammar and sound of 完成する (kansei suru). As a する-verb (suru-verb), it's quite regular. The noun part is 完成 (kansei), and する (suru) is the verb 'to do.' This means you can conjugate it like other する-verbs.

For example:

  • Present/Future: 完成します (kansei shimasu) - I will complete / It completes.
  • Past: 完成しました (kansei shimashita) - I completed / It was completed.
  • Negative: 完成しません (kansei shimasen) - I will not complete / It does not complete.
  • Te-form (for connecting clauses): 完成して (kansei shite)

Pronunciation is key! Kan-sei su-ru. The 'n' sound in 'kan' is like the 'n' in 'ink.' The 'sei' sounds like 'say.' The 'su' is like 'sue,' and 'ru' is a light flap, almost like a soft 'd' or 'l' sound, especially between vowels or at the end of words. Stress tends to be fairly even across syllables in Japanese, without strong emphasis like in English.

IPA (International Phonetic Alphabet) can help refine this:

  • British English approximation: /kæn.seɪ.sɯ.ɾɯ/
  • American English approximation: /kɑn.seɪ.sɯ.ɾu/

Rhyming words are tricky in Japanese as it's syllable-timed, but words ending in '-sei' or '-ru' might share some phonetic qualities. Think of words like sensei (teacher) or benkyou suru (to study).

Fun Fact

Many complex concepts and technical terms in Japanese were borrowed from Chinese, often using these powerful character combinations. 完成 (kansei) is a prime example of such a Sino-Japanese vocabulary word.

Pronunciation Guide

UK /kæn.seɪ.sɯ.ɾɯ/

Sounds like 'can-say-soo-roo', with the 'roo' having a very light 'd' or 'l' sound.

US /kɑn.seɪ.sɯ.ɾu/

Similar to British, 'kahn-say-soo-roo', the final 'u' is often unstressed and light.

Common Errors

  • Pronouncing 'su' too strongly.
  • Making the 'ru' sound too much like an English 'ru'.
  • Incorrectly stressing syllables; Japanese is more evenly stressed.

How to Use It

Formality Scale

most formal usage formal neutral casual

자주 하는 실수

Using 終わる (owaru) when emphasis on quality/perfection is needed. 完成する (kansei suru)
終わる simply means 'to end'. 完成する implies reaching a final, often high-quality state.
Confusing transitive and intransitive forms. The project completed (intransitive) vs. We completed the project (transitive).
完成する can act similarly to both, but context is key. Using the する verb form helps clarify.
Overusing it for very simple actions. Use simpler verbs like 終わる (owaru) or 終える (oeru) for everyday endings.
完成する often carries a weight of accomplishment that might be too much for just 'finishing lunch'.
Pronouncing 'sei' as 'say' instead of 'say' with a slightly longer 'e' sound. kan-SEI su-ru
Japanese vowels are generally pure and consistent. Get the 'ei' diphthong right.
Forgetting the 'o' particle with direct objects. レポートを完成する (repōto o kansei suru)
When 'kansei suru' acts transitively, the direct object typically takes the 'o' particle.

Practice the 'sei' sound – it's like the English word 'say'. And remember the 'ru' is a light flap, not a hard 'roo'.

💡

Avoid using 完成する for simple endings like finishing a meal. Stick to 終わる or 終える for those.

💡
