Character Breakdown

Understanding 慣例 (かんれい)

慣例 refers to customs, conventions, or precedents that are established by repeated practice over time. It is often used in formal or business contexts to describe standard procedures or traditional ways of doing things.

Usage and Nuance

When speakers use 慣例, they imply that the action or rule is not just a one-time decision but follows an established pattern accepted by a group or organization. It carries a sense of tradition and expectation.

Common Collocations

  • 慣例に従う (かんれいにしたがう): to follow the custom or precedent
  • 慣例を破る (かんれいをやぶる): to break the convention
  • 慣例として (かんれいとして): as a convention

These phrases are useful in discussing rules, traditions, or organizational behavior.

Register and Formality

慣例 is a formal noun and is commonly used in written language, business, legal, or official contexts. It is less common in casual conversation.

Learner Tip

A common confusion is mixing 慣例 with 習慣 (しゅうかん), which means personal habits or customs. 慣例 usually refers to collective or organizational customs rather than individual habits. Remember 慣例 is about established conventions shared by a group.
