悪くなる

waruku naru الأكثر شيوعاً #1,500

At the A1 level, learners focus on the most basic use of 'warukunaru' to describe simple changes in the world around them. The focus is on the combination of 'warui' (bad) and 'naru' (to become). A1 students learn to use this primarily for the weather ('Tenki ga warukunaru') and perhaps simple physical feelings ('Guai ga warukunaru'). The grammar is kept simple, usually in the present or past polite forms ('warukunarimasu', 'warukunarimashita'). At this stage, the word is a vital tool for expressing that something is no longer 'good' or 'okay'. It helps learners move beyond just saying 'It is bad' to 'It became bad'. The concept of 'naru' as a change of state is a major milestone for A1 learners, and 'warukunaru' is one of the most practical examples of this rule. They learn that they cannot say 'warui naru' and must change the 'i' to 'ku'. This is often their first introduction to adverbial forms of adjectives.

At the A2 level, the use of 'warukunaru' expands to include more varied subjects and slightly more complex sentence structures. Learners start using it to talk about their health in more detail ('Kaze o hiite, guai ga warukunatta'), their grades ('Seiseki ga warukunaru'), or the quality of things they use. They also begin to use it with basic conjunctions like 'kara' (because) or 'node'. For example, 'Ame ga furisou dakara, tenki ga warukunaru yo' (Because it looks like rain, the weather will get bad). A2 learners also start to encounter the 'te-form' of 'warukunaru', such as 'warukunatte...', to link ideas. They might also begin to use 'warukunaru' with 'shimau' to express regret: 'Warukunatte shimaimashita' (It unfortunately got bad). The focus at A2 is on increasing the frequency and variety of contexts where the phrase is applied, making it a natural part of their descriptive repertoire.

At the B1 level, which is the target level for this word, learners should be able to use 'warukunaru' fluently to describe trends, processes, and more abstract changes. This includes talking about the economy ('Keiki ga warukunaru'), social relationships ('Naka ga warukunaru'), and long-term changes like eyesight ('Me ga warukunaru'). B1 learners are expected to use 'warukunaru' in various conditional forms, such as 'warukunattara' (if it gets worse) or 'warukunareba' (if it becomes bad). They also start to distinguish 'warukunaru' from more formal synonyms like 'akka suru'. A B1 student can explain *why* something is getting worse using more complex grammar and a wider vocabulary. They also understand the nuance of using 'warukunaru' to soften a negative statement. For example, instead of saying 'This food is bad', they might say 'Aji ga warukunatta' to imply it was once good but has changed, which is often more polite and descriptive.

At the B2 level, learners use 'warukunaru' with a high degree of precision and can handle its use in more formal or literary contexts. They are comfortable using it in complex sentences involving relative clauses and advanced particles. B2 students can discuss the implications of something 'getting bad' in a broader social or professional context. For instance, they might discuss how 'Kankyou ga warukunaru koto de, seitaikei ni eikyou ga deru' (As the environment gets worse, it affects the ecosystem). They also understand the subtle difference in tone between 'warukunaru' and its synonyms and can choose the most appropriate one for the register. At this level, 'warukunaru' is often used in debates or essays to describe negative trajectories. B2 learners also master the use of 'warukunaru' in potential and passive-like constructions, and they can use it to describe complex psychological states or abstract concepts like 'reputation' (hyouban ga warukunaru).

At the C1 level, 'warukunaru' is used with native-like nuance, often appearing in sophisticated discussions about philosophy, politics, or high-level business strategy. C1 learners understand the idiomatic and metaphorical extensions of the phrase. They can use it to describe the 'worsening' of abstract concepts like 'public order' (chian ga warukunaru) or 'the flow of a conversation' (hanashi no nagare ga warukunaru). They are also adept at using 'warukunaru' within complex rhetorical structures, such as 'warukunaru ippou da' (it's only getting worse). At this level, the learner is aware of the historical and cultural connotations of the word and can use it to evoke specific moods or reactions. They can also critique the use of the word in media, noting when it is used to downplay or exaggerate a situation. The word becomes a tool for subtle persuasion and precise description in high-stakes communication.

At the C2 level, the learner has complete mastery over 'warukunaru' and its entire semantic field. They can use it in any context, from classical-style literature to modern slang, with perfect appropriateness. They understand the most subtle distinctions between 'warukunaru' and every possible synonym, including archaic or highly specialized terms. A C2 speaker can use 'warukunaru' to create irony, humor, or deep emotional resonance. They can discuss the linguistic evolution of the phrase and its role in the Japanese language system. In professional writing, they know exactly when to use 'warukunaru' to sound accessible and when to switch to 'akka' or 'teika' for professional authority. For a C2 learner, 'warukunaru' is not just a vocabulary item but a flexible instrument for expressing the myriad ways in which the world can decline, decay, or deviate from the ideal.

悪くなる في 30 ثانية

A fundamental Japanese phrase meaning 'to get worse' or 'to become bad', used for weather, health, and quality.
Grammatically formed by changing the i-adjective 'warui' to its adverbial form 'waruku' and adding the verb 'naru'.
Highly versatile, it appears in both casual conversations and formal reports, though 'akka suru' is a more formal synonym.
Essential for B1 learners to describe trends, changes in state, and to express concern about deteriorating situations.

The Japanese verb phrase 悪くなる (warukunaru) is a compound construction consisting of the i-adjective 悪い (warui - bad) and the intransitive verb なる (naru - to become). In its most literal sense, it describes a transition from a state of being good, neutral, or acceptable into a state that is undesirable, dysfunctional, or negative. This isn't just a static description of badness, but a dynamic observation of change over time. When you use this phrase, you are focusing on the process of deterioration. It is one of the most versatile expressions in the Japanese language, applicable to physical health, weather conditions, economic trends, interpersonal relationships, and even the quality of perishable goods like food. Understanding this word requires grasping the concept of 'naru' as a marker of natural change or resultative states. In Japanese culture, where the flow of time and the impermanence of things (mono no aware) are often highlighted, 'warukunaru' serves as a primary tool for reporting negative shifts in the environment or personal circumstances.

Core Concept: The shift from a positive or neutral state to a negative one, emphasizing the process of change.

最近、天気が悪くなることが多いですね。(Lately, there are many times when the weather gets bad, isn't there?)

In terms of semantic depth, 'warukunaru' can be used both for objective changes (like a machine breaking down) and subjective feelings (like a mood souring). It is often contrasted with 'yokunaru' (to get better). Linguistically, the transformation of 'warui' to 'waruku' is the adverbial form, which is necessary to modify the verb 'naru'. This grammatical pattern [Adjective-ku + naru] is a cornerstone of Japanese grammar. For example, when discussing health, 'taichou ga warukunaru' implies a decline in physical condition. This could range from a slight headache to a serious illness. The phrase is inherently neutral in terms of blame; it simply states that the condition has worsened, without necessarily pointing to a cause. However, when used in social contexts, such as 'naka ga warukunaru' (relationships getting bad), it carries a heavy emotional weight, suggesting conflict or distance between people who were once close.

Semantic Range: Includes physical decay, moral decline, worsening weather, health issues, and deteriorating social ties.

牛乳の匂いが悪くなる前に飲んでください。(Please drink the milk before the smell gets bad/spoils.)

Furthermore, 'warukunaru' is often used in the past tense 'warukunatta' to report a completed change. 'Kibun ga warukunatta' (I started feeling sick/my mood worsened) is a common way to excuse oneself from a situation. In more formal or academic settings, while 'warukunaru' is perfectly acceptable, you might encounter more specific verbs like 'akka suru' (to deteriorate/exacerbate). However, 'warukunaru' remains the go-to expression for daily life because of its simplicity and broad applicability. It captures the essence of the 'bad' state without the clinical or technical overtones of 'akka'. Whether you are talking about the economy (keiki ga warukunaru) or your eyesight (me ga warukunaru), this phrase provides a clear, concise way to communicate a negative trajectory. Its importance in the CEFR B1 level lies in the learner's ability to describe changes and trends, moving beyond static descriptions of the world.

Usage Frequency: Extremely high in both spoken and written Japanese across all levels of formality.

二人の仲が悪くなる原因は何だったのか。(What was the cause of the relationship between those two getting bad?)

Using 悪くなる (warukunaru) correctly involves understanding the conjugation of i-adjectives and the function of the verb 'naru'. To form this phrase, you take the i-adjective 悪い (warui), remove the final 'i', and add 'ku'. This creates the adverbial form 'waruku'. Then, you simply attach the verb 'naru' (to become). This structure is the standard way to express 'to become [adjective]' in Japanese. Because 'naru' is a Godan verb (Group 1), it conjugates regularly: narimasu (polite), naru (plain), natta (past), naranai (negative). When you want to say something 'has gotten worse', you use the past tense: 'warukunatta' or 'warukunarimashita'. If you are predicting that something 'will get worse', you use the present/future form: 'warukunaru' or 'warukunarimasu'.

Grammar Rule: [I-Adjective minus 'i'] + ku + naru. Example: 悪い -> 悪く + なる.

タバコを吸うと、健康が悪くなる可能性が高い。(If you smoke, there is a high possibility your health will get worse.)

The subject of 'warukunaru' is usually marked with the particle 'ga' or 'wa'. For instance, 'Tenki ga warukunaru' (The weather gets bad). It is important to distinguish this from the transitive version, 'waruku suru' (to make something bad/worsen something), where an agent is actively causing the decline. 'Warukunaru' is an automatic or natural change. For example, if you say 'Kare wa kuiki o waruku shita' (He made the atmosphere bad), it implies he did something to cause it. But if you say 'Kuiki ga warukunatta' (The atmosphere got bad), it focuses on the state of the room itself. This distinction is crucial for B1 learners who are starting to navigate the nuances of transitivity and agency in Japanese. Another common usage is with 'te-form' to show cause and effect: 'Ame ga futte, michi ga warukunatta' (It rained, and the road conditions got bad).

Conjugation Examples: Warukunaru (Plain), Warukunarimasu (Polite), Warukunatta (Past), Warukunarimashita (Polite Past), Warukunareba (Conditional).

もし症状が悪くなったら、すぐに病院へ行ってください。(If the symptoms get worse, please go to the hospital immediately.)

In conversation, 'warukunaru' is frequently paired with adverbs of degree to specify how much worse something is getting. 'Dandan warukunaru' (gradually getting worse), 'kyuu ni warukunaru' (suddenly getting worse), and 'motto warukunaru' (getting even worse) are all common collocations. For B1 students, mastering these combinations allows for more precise descriptions of events. Furthermore, 'warukunaru' can be used metaphorically. 'Atama ga warukunaru' (to get stupid/lose one's edge) or 'mimi ga warukunaru' (to lose one's hearing) are standard ways to describe the decline of faculties. When describing food, 'aji ga warukunaru' means the flavor has deteriorated, often implying it is no longer fresh. The versatility of this phrase cannot be overstated; it is a fundamental building block for expressing any negative progression in the Japanese language.

Common Collocations: Tenki ga... (Weather), Taichou ga... (Health), Naka ga... (Relationship), Keiki ga... (Economy), Shishitsu ga... (Quality).

景気が悪くなると、失業者が増えます。(When the economy gets bad, the number of unemployed people increases.)

You will encounter 悪くなる (warukunaru) in a vast array of contexts, ranging from the most casual daily conversations to formal news broadcasts. In daily life, it is most frequently heard in discussions about the weather and health. If you are in Japan, you will often hear people say 'Tenki ga warukunaru sou desu ne' (It looks like the weather will get bad, doesn't it?) during small talk. Similarly, in a medical context, a doctor might ask, 'Itsu kara guai ga warukunarimashita ka?' (Since when did you start feeling bad?). This phrase is the standard, polite way to discuss a decline in physical well-being. It is also a staple of interpersonal drama; in anime or TV dramas, characters often lament 'Futari no kankei ga warukunatta' (The relationship between the two has worsened), signaling a plot shift toward conflict.

Context: Weather Forecasts: Used to predict rain, storms, or declining visibility. 'Gogo kara tenki ga warukunaru mikomi desu' (The weather is expected to worsen from the afternoon).

今夜から視界が悪くなるので、運転には注意してください。(Visibility will get bad from tonight, so please be careful while driving.)

In the business world and news media, 'warukunaru' is used to describe economic downturns or deteriorating market conditions. Headlines such as 'Keiki ga warukunaru choushou' (Signs of the economy getting bad) are common. While formal reports might use 'akka' (deterioration), 'warukunaru' is used in interviews and explanatory segments to make the information more accessible to the general public. You will also hear it in the context of technology and infrastructure. For example, if a Wi-Fi signal is dropping, someone might say 'Denpa ga warukunatta' (The signal got bad). If a road is under construction and difficult to pass, 'Michi ga warukunatteiru' (The road has become bad/rough) is a natural way to describe it. It is a word that bridges the gap between technical description and everyday observation.

Context: Business & Economy: Used for stock market drops, declining sales, or worsening corporate relations. 'Torihikisaki to no kankei ga warukunaru' (Relationships with clients getting bad).

原材料の高騰で、収益が悪くなる一方だ。(Due to the rising cost of raw materials, profits are only getting worse.)

Furthermore, in the context of education and parenting, you might hear 'Seiseki ga warukunaru' (Grades getting bad). This is a common concern for students and parents alike. In sports, a commentator might say 'Chiimu no fun'iki ga warukunatta' (The team's atmosphere has worsened) after a series of losses. The phrase is also used in environmental discussions, such as 'Kankyou ga warukunaru' (The environment getting bad/polluted). Because it is so ubiquitous, hearing 'warukunaru' acts as a universal red flag in Japanese, signaling that a situation is trending in the wrong direction. Whether it's the quality of a product, the mood of a room, or the state of the world, this phrase is the primary linguistic vehicle for conveying negative change.

Context: Daily Life: Used for food spoiling, eyesight declining, or a bad mood. 'Kibun ga warukunaru' (To feel sick or get in a bad mood).

スマホの見すぎで、目が悪くなるよ。(Your eyesight will get bad from looking at your smartphone too much.)

One of the most frequent mistakes learners make with 悪くなる (warukunaru) is confusing it with its transitive counterpart, 悪くする (waruku suru). While 'warukunaru' means 'to become bad' (intransitive), 'waruku suru' means 'to make something bad' (transitive). For example, if you say 'Watashi wa tenki o warukunatta' (I became the weather bad), it is grammatically incorrect and nonsensical. You should say 'Tenki ga warukunatta' (The weather got bad). Conversely, if you want to say someone made a situation worse, you must use 'waruku shita'. Understanding the 'ga' (subject) vs. 'o' (object) distinction is vital here. Another common error is failing to use the adverbial 'ku' form. Beginners often say 'warui naru', which is a direct violation of Japanese grammar rules for i-adjectives.

Mistake 1: Transitivity Confusion: Using 'warukunaru' when an active agent is causing the worsening. Correct: 'Kare ga kankei o waruku shita' (He worsened the relationship). Incorrect: 'Kare ga kankei o warukunatta'.

× 彼は空気を悪くなった。
○ 彼は空気を悪くした。(He made the atmosphere bad.)

Another nuance that learners often miss is the difference between 'warukunaru' and 'akka suru'. While 'warukunaru' is broad and general, 'akka suru' (deteriorate/exacerbate) is more formal and often used for medical conditions or serious social issues. Using 'akka suru' to talk about a slightly bad mood might sound overly dramatic or clinical. Conversely, using 'warukunaru' in a highly technical medical paper might seem slightly too casual, though it is not strictly wrong. Learners also sometimes struggle with the tense. In Japanese, 'warukunaru' (present) can mean 'it is about to get bad' or 'it generally gets bad'. If the change has already happened, you must use 'warukunatta'. Saying 'Taichou ga warukunaru' when you are already feeling sick will sound like a prediction rather than a statement of your current state.

Mistake 2: Incorrect Adjective Form: Using the dictionary form 'warui' instead of 'waruku'. Correct: 'Waruku naru'. Incorrect: 'Warui naru'.

× 視力が悪いなる。
○ 視力が悪くなる。(Eyesight gets bad.)

A more subtle mistake involves the use of 'warukunaru' with people. If you say 'Tanaka-san wa warukunatta', it could mean Tanaka-san's health got bad, or it could mean his personality became bad (he became a 'bad person'). Without context, this can be ambiguous. Usually, to specify health, you should say 'Tanaka-san wa taichou ga warukunatta'. To specify character, 'Tanaka-san wa seikaku ga warukunatta'. Also, avoid using 'warukunaru' for things that 'break' in a mechanical sense. While 'Kikai ga warukunaru' (The machine is getting bad/unreliable) is possible, if it's actually broken, 'kowareru' is the correct verb. 'Warukunaru' describes a decline in quality or state, not necessarily a total failure of function. Finally, be careful with the 'te-form' + 'shimau' (warukunatte shimau), which adds a nuance of regret. Forgetting this can make your statement sound too objective when you actually feel sorry about the situation.

Mistake 3: Over-generalization: Using 'warukunaru' for mechanical breaks. Correct for machines: 'Kowareru'. 'Warukunaru' is for quality/condition.

× パソコンが悪くなったから動かない。
○ パソコンが壊れたから動かない。(The PC broke, so it doesn't work.)

While 悪くなる (warukunaru) is the most common way to express worsening, several other words and phrases offer more specific nuances. The most prominent synonym is 悪化する (akka suru). While 'warukunaru' is a general term used in daily conversation, 'akka suru' is a Sino-Japanese (kango) compound that sounds more formal, technical, or serious. It is the standard term in medical, political, and economic reports. For example, a doctor would say 'shoujou ga akka shita' (symptoms deteriorated) in a formal report, but might say 'warukunarimashita ne' to the patient. Another similar term is 低下する (teika suru), which means 'to decline' or 'to drop'. This is used specifically for measurable qualities like 'kinou' (function), 'nouryoku' (ability), or 'shitsu' (quality). While 'warukunaru' is qualitative, 'teika suru' often implies a quantitative decrease.

Comparison: Warukunaru vs. Akka suru: Warukunaru: General, daily use, covers all 'bad' changes.
Akka suru: Formal, clinical, used for serious deterioration of conditions or situations.

病状が悪化するのを防ぐ必要があります。(It is necessary to prevent the medical condition from deteriorating.)

Then there is 落ちる (ochiru), which literally means 'to fall'. In certain contexts, it functions as a synonym for 'warukunaru', particularly regarding quality (shitsu ga ochiru) or grades (seiseki ga ochiru). Using 'ochiru' emphasizes a drop from a previously high standard. Another interesting comparison is with 崩れる (kuzureru), which means 'to crumble' or 'to lose shape'. This is specifically used for the weather (tenki ga kuzureru) or physical posture/form. When the weather 'kuzureru', it implies it was good but is now breaking down into rain or wind. Similarly, 腐る (kusaru) means 'to rot' or 'to spoil'. While you could say 'food gets bad' (tabemono ga warukunaru), 'kusaru' is the more specific and visceral term for biological decay. Choosing between these depends on the level of specificity and formality you wish to convey.

Comparison: Warukunaru vs. Teika suru: Warukunaru: 'The quality got bad' (subjective/general).
Teika suru: 'The quality declined' (objective/technical).

サービスの質が低下しているという苦情が来た。(We received complaints that the quality of service is declining.)

For interpersonal relationships, you might also see こじれる (kojireru), which means 'to get complicated' or 'to turn sour'. While 'naka ga warukunaru' is a simple statement that a relationship is bad, 'kojireru' implies that the situation has become tangled and difficult to resolve, often due to misunderstandings. In terms of health, 害する (gaisuru) means 'to harm' or 'to damage'. It is often used in the phrase 'kenkou o gaisuru' (to damage one's health), which is a more active and formal way of saying 'health gets bad'. Lastly, 衰える (otooroeru) means 'to weaken' or 'to decline' due to age or loss of vigor. You would use this for 'tairyoku' (physical strength) or 'kioku-ryoku' (memory). Understanding these synonyms allows a B1 learner to move from 'basic' Japanese to a more nuanced and expressive level, choosing the exact word that fits the context's gravity and specific nature.

Synonym Summary: Akka suru (Deteriorate), Teika suru (Decline), Ochiru (Drop), Kuzureru (Crumble), Kojireru (Get complicated), Kusaru (Rot).

話し合いがこじれて、解決が難しくなった。(The discussion got complicated, making a resolution difficult.)
