entity
1
extreme foolishness or irrationality
Very foolish or dangerous behavior or ideas that do not show good thinking.
用法パターン：
[something] is sheer madness
よくある間違い：
Learners sometimes think this meaning always refers to medical mental illness. In everyday speech, calling something "madness" here is usually a strong way to say it is very foolish or risky, not a medical description.

|

2
severe mental illness or insanity
A serious mental problem that makes a person lose normal control of thoughts, feelings, and actions.
用法パターン：
[someone] descends into madness
よくある間違い：
Learners may use "madness" in serious, real‑life medical contexts where modern speakers often prefer terms like "mental illness" or specific diagnoses. "Madness" is common in stories, historical writing, or dramatic speech, but can sound insensitive in clinical or respectful discussion.
類義語
insanity (Very close in meaning; similarly non‑technical and can sound dramatic or old‑fashioned in medical contexts.)
対義語
sanity (Refers to a normal, healthy state of mind, the direct opposite of madness in this sense.)
|
mental health (Neutral, modern term for a healthy mind, often preferred in clinical or respectful discussion.)

3
extreme excitement or enthusiasm
Very strong excitement or love for something, often by many people at the same time.
用法パターン：
[activity] madness
よくある間違い：
Learners sometimes use "madness" here when a simpler word like "excitement" is enough. "Madness" makes the feeling sound much stronger and more chaotic, so it fits big events or strong trends, not just normal interest.
類義語
mania (Suggests very strong excitement or fashion; can be used in both casual and slightly formal contexts.)
|
craze (Emphasizes a strong but often short‑lived popular interest.)
対義語
apathy (Lack of interest or enthusiasm, the opposite of shared madness for something.)
|
disinterest (Not caring about something that others might be excited about.)

brief period of foolish impulse
A short time when a person does something very foolish because they do not think carefully.
用法パターン：

Learners may mix this sense with long‑term mental illness. Phrases like "a moment of madness" or "a fit of madness" almost always describe a short, foolish action, not a medical condition.
類義語
impulse (Focuses on acting suddenly without thinking; does not itself sound as strong or critical as madness.)
|
rush of blood (Informal phrase for a sudden emotional reaction that leads to unwise action.)
対義語
self-control (The ability to stop yourself from acting on foolish impulses.)
|
clear thinking (Careful, calm thought that stops you from doing something in a moment of madness.)
