Character Breakdown

Meaning and Usage

「法則」(ほうそく) refers to a law or rule, often describing natural laws, scientific principles, or established rules that govern behavior or phenomena. It is commonly used in academic, scientific, and formal contexts.

Common Contexts

  • Natural laws (自然の法則)
  • Scientific or mathematical rules (数学の法則)
  • Social or behavioral rules (社会の法則)

Collocations and Patterns

  • 自然の法則: laws of nature
  • 数学の法則: mathematical rules
  • 法則を守る: to follow a rule or law
  • 法則に従う: to obey a law or rule

Register and Nuance

This word is formal and often used in written or academic language. It implies a principle or rule that is generally accepted or scientifically proven, rather than casual or arbitrary rules.

Common Mistake

Learners sometimes confuse 「法則」 with 「規則」 or 「ルール」, which also mean rules but are more often used for social or organizational rules. 「法則」 is more about universal or scientific principles, so use it when referring to laws of nature, science, or fundamental principles.
