Explanation at your level:
Hello! Today we learn a word about getting sick. The word is 発症する (hasshō suru). It means a sickness starts. Like, if you get a cold, your cold starts. That is 発症する. It is like the first day you feel sick. You don't say 'I 発症する' for a small cough, but for a real sickness, like flu, it can 発症する. It is a verb, an action word. Remember, it means the sickness *starts*.
Hi there! We're learning 発症する (hasshō suru), which means 'to develop a disease' or 'to fall ill'. Think about when a sickness begins. For example, if someone has diabetes, the disease might 発症する when they are older. It's the point when the illness starts to show symptoms. It's a formal word, often used in news or when talking about health seriously. You wouldn't use it for a simple headache, but for more significant health issues, it's the right word to describe their beginning.
Let's explore 発症する (hasshō suru), meaning 'to develop a disease' or 'to have the onset of an illness'. This verb is crucial when discussing the beginning stages of a medical condition. For instance, a doctor might explain that a certain genetic predisposition increases the risk of a disease 発症する later in life. It implies the transition from a healthy state or a latent condition to an active, symptomatic one.
You'll often hear it in contexts discussing risk factors, age of onset, or the progression of chronic illnesses. For example, 'This condition tends to 発症する in adults over 40.' Understanding this verb helps you grasp more detailed health information.
The Japanese verb 発症する (hasshō suru) signifies the clinical onset of a disease or condition. It's more precise than simply saying 'to get sick' and is frequently used in medical literature, public health announcements, and discussions about epidemiology. It denotes the moment when the pathological process becomes clinically apparent, manifesting in observable symptoms or signs.
Consider its use in sentences like: 'Early detection is key, as the disease can 発症する rapidly once symptoms appear.' or 'Environmental factors are known to trigger the 発症する of certain autoimmune disorders.' This term highlights the transition from subclinical to clinical phases of a disease.
発症する (hasshō suru) is a formal verb denoting the clinical manifestation or onset of a disease. It implies a specific point in time when a latent pathological process becomes evident through symptoms or diagnostic criteria. This term is indispensable in academic medical discourse, research papers, and clinical trial documentation.
For example, a study might investigate 'factors influencing the age of 発症する' for a particular illness, or discuss 'preventative measures to delay or avert the 発症する of chronic conditions'. The verb carries a strong connotation of a definitive beginning, often following a period of incubation or development, and is used when precision is paramount in describing the disease trajectory.
In advanced medical and scientific Japanese, 発症する (hasshō suru) refers to the precise moment a disease or pathological state transitions from a subclinical or latent phase to a clinically recognizable one. It signifies the overt manifestation of a condition, often marked by the appearance of specific signs and symptoms that allow for diagnosis. The term is crucial in fields like epidemiology, clinical pathology, and pharmacology when discussing disease progression, risk stratification, and the efficacy of interventions aimed at preventing or delaying onset.
Discussions involving 発症する might delve into complex etiological pathways, genetic predispositions, environmental triggers, and the precise timing of disease initiation. For instance, research might focus on identifying biomarkers that predict the likelihood of a condition 発症する years before clinical symptoms emerge, or analyzing the statistical probability of onset within specific demographic groups. Its usage demands a nuanced understanding of medical terminology and the biological processes underlying disease development.

- 発症する means 'to develop a disease' or 'onset of illness'.
- It's a formal verb used in medical and health contexts.
- It signifies the beginning of a disease becoming apparent.
- Key collocations include 発症リスク (onset risk) and 早期発症 (early onset).
Hey there! Let's dive into the Japanese verb 発症する (hasshō suru). Simply put, it means 'to develop a disease' or 'to fall ill'. Think of it as the moment when a sickness officially starts showing its face. It's not just about *having* a disease, but about the *beginning* of it becoming apparent.
This verb is super useful when you're talking about health, medicine, or even just how someone is feeling. For example, you might hear about a condition '発症する' at a certain age, or that a particular factor can cause a disease to '発症する'. It’s all about that initial stage of illness.
We often use it in more formal or medical contexts, but it's a key term to understand when discussing health in Japanese. So, next time you hear about someone getting sick, remember this word signifies the *start* of that sickness!
The word 発症する (hasshō suru) is a compound verb made up of two main parts: 発症 (hasshō) and the verb する (suru). Let's break down 発症!
発 (hatsu) is a kanji that means 'to start', 'to issue', or 'to emit'. You see it in words like 発表 (happyō - announcement) or 出発 (shuppatsu - departure). It carries the sense of beginning or sending something out.
症 (shō) is the kanji for 'symptom' or 'disease'. It's a crucial character in medical terminology, appearing in words like 病症 (byōshō - illness) or症状 (shōjō - symptom). It directly relates to the manifestation of a health condition.
So, 発症 literally means 'start of symptoms' or 'onset of disease'. When you add する (suru), the common verb 'to do', it becomes the active verb 'to develop symptoms' or 'to fall ill'. The term itself is relatively modern, gaining prominence with the development of scientific medicine and the need for precise terminology to describe the clinical progression of diseases.
発症する (hasshō suru) is primarily used in medical and health-related discussions. It's the go-to verb when you want to talk about the *beginning* of a disease or condition. You’ll often find it in news reports about public health, medical journals, and doctor-patient conversations.
Common collocations include talking about *when* a disease might develop, or *what factors* might lead to its development. For instance:
- 病気が発症する (byōki ga hasshō suru) - a disease develops
- 症状が発症する (shōjō ga hasshō suru) - symptoms appear (though 症状が出る - shōjō ga deru is more common for general symptoms)
- 特定の年齢で発症する (tokutei no nenrei de hasshō suru) - to develop at a specific age
- ストレスが原因で発症する (sutoresu ga gen'in de hasshō suru) - to develop due to stress
While it's a formal term, it's not overly academic. It's the standard way to express the onset of an illness. You wouldn't typically use it for very mild, temporary ailments like a common cold unless you were discussing its clinical progression. For everyday complaints, simpler phrases are more common.
While 発症する (hasshō suru) itself is a standard verb and not part of many idiomatic expressions, the concept of disease onset is present in various Japanese sayings. Here are a few related ideas:
- 病は気から (yamai wa ki kara) - 'Illness comes from the mind.' This proverb suggests that one's mental state can influence their physical health, and a negative mindset might even lead to illness. It touches upon the idea of developing sickness, but from a psychological perspective.
- 風邪をひく (kaze o hiku) - 'To catch a cold.' This is the most common way to say you've developed a minor illness like a cold. It's casual and everyday, unlike the more formal '発症する'.
- 体調を崩す (taichō o kuzusu) - 'To fall ill' or 'to be in poor health.' This is a general phrase for feeling unwell or developing some kind of sickness, less specific than '発症する'.
- 熱を出す (netsu o dasu) - 'To have a fever.' This describes a specific symptom that often accompanies the onset of a disease.
- 発作を起こす (hossa o okosu) - 'To have a seizure/attack.' This is used for sudden, acute episodes of illness, like epilepsy or asthma attacks, which are a type of '発症' but more specific to sudden episodes.
These expressions show different ways the Japanese language talks about getting sick, ranging from psychological causes to specific symptoms and general unwellness.
発症する (hasshō suru) is a Group 2 verb (ichidan verb) in Japanese grammar. This makes it quite regular and easy to conjugate!
Conjugation Basics:
- Masu-form (polite): 発症します (hasshō shimasu)
- Te-form: 発症して (hasshō shite)
- Past tense: 発症した (hasshō shita)
- Negative: 発症しない (hasshō shinai)
- Potential: 発症できる (hasshō dekiru)
- Volitional: 発症しよう (hasshō shiyō)
Pronunciation:
The standard pronunciation is hasshō suru.
- ha - like the 'ha' in 'hat'
- ssho - this is a doubled 's' sound, creating a slight pause before the 'sho'. The 'sho' is like the 'show' in 'showtime'.
- su - like the 'su' in 'sun'
- ru - a light 'r' sound, similar to the 'tt' in the American pronunciation of 'butter'.
IPA (approximate):
- British English: /hæˈʃɔː sʊˈɹuː/
- American English: /hæˈʃɔː sʊˈɹuː/
Stress: Stress in Japanese is generally flatter than in English, but there's a slight emphasis on the 'shō' syllable.
Rhyming Words: Finding perfect rhymes in Japanese is tricky due to the limited syllable sounds. Words ending in '-ō suru' might be considered near rhymes, like 増加する (zōka suru - to increase) or 増加する (zōka suru - to increase).
Fun Fact
The kanji 症 (shō) itself is composed of 'illness' (疒) and 'start' (少), suggesting the beginning of sickness.
Pronunciation Guide
Sounds like 'ha-SHOW-ssu-roo', with a slight pause before 'show' and a light 'r' sound at the end.
Similar to UK, 'ha-SHOW-ssu-roo', emphasizing the doubled 's' sound.
Common Errors
- Pronouncing 'ssho' as 'sho' (hashō suru).
- Making the 'r' sound too strong.
- Incorrect stress, putting too much emphasis on the wrong syllable.

How to Use It
Formality Scale
Erreurs courantes
発症する implies the formal onset of a disease, not just feeling a bit unwell.
These are opposite concepts in the timeline of a disease.
Forgetting to drop the final 'ru' before adding endings like '-masu' or '-nai' is a common error for learners.
発症する specifically refers to the onset, not the ongoing condition.
Saying 'hashō' instead of 'hasshō' changes the word.
Tips
Connect to 'Hassle'
Remember that developing a disease can be a real 'hassle'. Link 'HASSLE' to 'HAS-SHO' (発症) to recall the meaning of onset/developing illness.
Respectful Language
Using precise medical terms like 発症する shows you understand the gravity of health conditions and communicate respectfully.
Easy Conjugation
As an ichidan verb, 発症する is easy to conjugate! Just remember to drop the final 'ru' before adding endings like -masu, -nai, -ta.
Double the S!
Pay attention to the 'ssho' sound (はっしょ). That doubled 's' sound is important for correct pronunciation and distinguishing it from similar sounds.
Don't Overuse It!
Avoid using 発症する for everyday ailments like a slight headache or a minor cough. Stick to 病気になる or 体調を崩す for those.
Kanji Clues
The kanji 症 (shō) itself contains the radical 疒 (sickness) and 少 (few/little/start), hinting at the 'start of sickness'.
Read Medical News
Read Japanese news articles about health or medical research. You'll see 発症する used frequently in context, helping you internalize its meaning and usage.
Think 'Onset'
Whenever you see 発症する, think of the word 'onset' in English. It's a direct conceptual link.
Create Scenarios
Imagine different disease scenarios (e.g., diabetes, flu, a new virus) and practice using 発症する to describe when they start.
