Character Breakdown

Meaning and Usage

"生物" (せいぶつ) refers broadly to living things or organisms, including animals, plants, and microorganisms. It is a common term used in scientific contexts such as biology classes and environmental discussions.

Common Contexts

You will often see "生物" used in educational settings, especially in biology (生物学) or when talking about ecosystems and habitats. It can refer to any living entity, from microscopic cells to large animals.

Collocations and Patterns

  • 生物学 (せいぶつがく): biology, the scientific study of living things.
  • 生物の授業: biology class.
  • 珍しい生物 (めずらしいせいぶつ): rare organisms, often used in nature documentaries or scientific reports.
  • 生物が住む/生息する: living things inhabit or live in a place.

Register and Nuance

"生物" is a neutral, formal term suitable for academic, scientific, and general use. It is not typically used in casual conversation when referring to pets or animals; in those cases, more specific words like "動物" (どうぶつ) might be preferred.

Common Learner Mistake

Learners sometimes confuse "生物" with "動物" (animals). Remember, "生物" includes all living things, not just animals. Using "生物" when you mean specifically animals can sound overly broad or scientific.
