Character Breakdown

Understanding 機構

The word 機構 (きこう) can refer to both a physical mechanism and an organizational structure. It is commonly used in technical contexts to describe how parts work together mechanically, as well as in social or corporate contexts to describe institutions or organizational frameworks.

Usage Nuances

When referring to machines or devices, 機構 emphasizes the functional mechanism or system that enables operation. In organizational contexts, it denotes a formal structure or institution, such as a government agency or international body.

Common Collocations

  • 機構が動く (きこうがうごく): the mechanism operates — used when describing mechanical function.
  • 国際機構 (こくさいきこう): international organization — refers to global institutions.
  • 機構改革 (きこうかいかく): organizational reform — used in business or government contexts.

Register and Formality

機構 is a formal term often found in written language, technical documents, and official discourse. It is less common in casual conversation unless discussing technical or organizational topics.

Learner Tips

A common confusion is mixing 機構 with 機械 (きかい), which means 'machine.' 機構 focuses on the mechanism or structure behind a system, while 機械 refers to the machine itself. Remember that 機構 can be abstract (an organization) or concrete (a mechanical system).
