개선되다 in 30 Sekunden
- 개선되다 means 'to be improved' or 'to get better' in a formal or systematic sense.
- It is the passive version of 개선하다 (to improve something).
- Commonly used for environments, systems, habits, and quality.
- It does not take a direct object (no -을/를).
The Korean verb 개선되다 (gaeseondoeda) is a passive construction derived from the noun 개선 (gaeseon), which means 'improvement' or 'reform'. In the Korean language, the suffix -되다 is often attached to Hanja-based nouns to indicate that a state is being achieved or a process is happening to the subject, often without a specific agent mentioned. Therefore, 개선되다 literally translates to 'to become improved' or 'to be improved'. This word is ubiquitous in Korean society, appearing in everything from news reports about the economy to personal conversations about health or relationships.
- Hanja Origin
- 改 (개 - change/correct) + 善 (선 - good). Together, they imply changing something for the better.
- Grammatical Function
- It functions as an intransitive verb in Korean, meaning it does not take a direct object (marked by 을/를). Instead, the thing that improves is the subject (marked by 이/가).
- Nuance
- Unlike the simple '좋아지다' (to get better), '개선되다' implies a systematic or structural change. It suggests that flaws were identified and corrected.
"수질이 많이 개선되었다."
— Translation: The water quality has improved significantly.
When you use this word, you are focusing on the result of a process. For instance, if a company changes its customer service policy and the feedback becomes positive, you would say the service has been '개선되었다'. It is particularly common in formal contexts, such as business, politics, and technology. You will see it in headlines like 'Traffic conditions improved' (교통 상황 개선) or 'User interface improved' (사용자 인터페이스 개선). It carries a sense of progress and modernization.
"제도가 개선되기를 바랍니다."
— Translation: I hope the system will be improved.
Understanding the difference between 개선하다 (to improve something - active) and 개선되다 (to be improved - passive) is crucial for A2 and B1 learners. While '개선하다' focuses on the person or entity doing the work, '개선되다' focuses on the subject that is undergoing the positive change. For example, '정부가 제도를 개선했다' (The government improved the system) vs. '제도가 개선되었다' (The system was improved).
- Common Subjects
- Environment (환경), System (제도), Relationship (관계), Quality (품질), Performance (성능).
"두 나라의 관계가 개선되고 있다."
— Translation: The relationship between the two countries is improving.
Using 개선되다 correctly requires understanding its passive nature. Because it ends in -되다, it usually follows a subject marked with -이/가 or -은/는. You should avoid using the object marker -을/를 with this verb. For example, saying '환경을 개선되다' is grammatically incorrect; it must be '환경이 개선되다'.
In terms of conjugation, it follows the standard rules for -하다/-되다 verbs:
- Present Tense: 개선돼요 (Polite), 개선된다 (Plain)
- Past Tense: 개선됐어요 (Polite), 개선되었다 (Written/Formal)
- Future Tense: 개선될 거예요 (Polite), 개선될 것이다 (Formal)
This verb is often paired with adverbs that describe the degree or speed of improvement. Common adverbs include 많이 (a lot), 상당히 (considerably), 점차 (gradually), and 획기적으로 (drastically). For instance, '기술이 획기적으로 개선되었다' means 'The technology has been drastically improved'.
"근무 환경이 점차 개선되고 있습니다."
— Translation: The working environment is gradually improving.
In formal writing, such as reports or essays, 개선되다 is preferred over more colloquial terms like '나아지다'. It sounds more objective and professional. If you are writing a TOPIK essay about social issues, using this word will help you achieve a higher score. It shows that you understand the formal register of the Korean language.
You will encounter 개선되다 in various settings, ranging from the news to corporate meetings. It is a staple of 'official' Korean. Here are the most common places you'll hear it:
1. News and Media
News anchors frequently use this word when reporting on the economy, public safety, or social changes. '수출 실적이 개선되었습니다' (Export performance has improved) or '교통 체증이 개선될 것으로 보입니다' (Traffic congestion is expected to improve). It provides a formal tone to the reporting.
2. Workplace and Business
In a Korean office, you'll hear this during performance reviews or project updates. Managers might say, '업무 프로세스가 많이 개선되었네요' (The work process has improved a lot). It is also common in customer feedback responses: '불편한 점이 개선되도록 노력하겠습니다' (We will strive to improve the points of inconvenience).
3. Technology and Software
App update logs are a great place to see this word. '버그가 수정되고 성능이 개선되었습니다' (Bugs fixed and performance improved). In this context, it refers to technical optimization and user experience enhancements.
"이번 업데이트로 배터리 효율이 개선되었습니다."
— Translation: Battery efficiency has been improved with this update.
4. Public Announcements
Subway announcements or government notices often use this word to talk about service changes. '환승 시스템이 개선되어 더욱 편리해졌습니다' (The transfer system has been improved, making it more convenient).
Even though 개선되다 is a common word, learners often make specific errors when using it. Understanding these pitfalls will help you sound more like a native speaker.
1. Using the wrong particle
The most frequent mistake is using the object marker -을/를. Remember, -되다 verbs are passive/intransitive.
❌ 틀린 표현: 문제를 개선되다 (Incorrect)
✅ 옳은 표현: 문제가 개선되다 (Correct)
2. Confusing with '좋아지다'
While they both mean 'to get better', 개선되다 is for things that can be 'fixed' or 'reformed'. You wouldn't usually say '날씨가 개선되었다' (The weather improved) because weather isn't a system or a flaw to be fixed. Instead, use '날씨가 좋아졌다'. Use 개선되다 for things like laws, habits, or machine parts.
3. Overusing in casual speech
If you are talking to a close friend about your mood, saying '기분이 개선되었어' sounds very robotic and strange. In casual conversation, stick to '기분이 좋아졌어' or '나아졌어'. Save 개선되다 for formal or semi-formal contexts.
"성적이 개선됐다 (O) vs 기분이 개선됐다 (X)"
— Note: Grades can be improved (systematic), but mood just 'gets better'.
4. Misspelling '개선'
Some learners confuse it with '계선' or '개설'. '개설' (gaeseol) means 'to open/establish' (like a bank account or a class). Make sure to use '개선' for improvement.
Korean has several words for 'improvement' or 'getting better'. Choosing the right one depends on the context and the degree of formality.
- 향상되다 (Hyangsang-doeda)
- Means 'to be enhanced' or 'to advance'. It is often used for skills, abilities, or technical performance. Example: '실력이 향상되다' (Skills improved).
- 나아지다 (Naajida)
- A more general and slightly less formal term for 'to get better'. It can be used for health, situations, or quality. Example: '형편이 나아지다' (Circumstances improved).
- 호전되다 (Hojeon-doeda)
- Specifically used for medical conditions or worsening situations that turn for the better. Example: '병세가 호전되다' (The patient's condition improved).
- 증진되다 (Jeungjin-doeda)
- Means 'to be promoted' or 'to be increased', often used for health or welfare. Example: '건강이 증진되다' (Health was promoted/improved).
The main difference is that 개선되다 implies a 'fix' to a 'problem'. If something was broken, inefficient, or wrong, and then it was made better, 개선되다 is the perfect word. 향상되다 is more about going from 'good' to 'better' or 'better' to 'best'.
"품질이 개선되다 (Fixing defects) vs 실력이 향상되다 (Leveling up skills)"
