Character Breakdown

Understanding 研究 (けんきゅう)

The word 研究 primarily means "research" or "study" and is used in academic, scientific, and professional contexts. It refers to the systematic investigation or examination of a subject to discover new information or reach new conclusions.

Common Uses

  1. Scientific or academic research: Often used when talking about studying a specific topic deeply, such as medicine, environment, or technology.
  2. Research projects: Can describe ongoing or completed research activities.
  3. General investigation: Sometimes used more broadly for any detailed study or inquiry.

Collocations and Patterns

  • 研究をする (けんきゅうをする): to do research
  • 研究を始める (けんきゅうをはじめる): to start research
  • 研究分野 (けんきゅうぶんや): research field
  • 研究成果 (けんきゅうせいか): research results

These collocations are common in academic and professional settings.

Usage Notes

When using 研究, it often implies a formal or serious study rather than casual learning. It is common in university, laboratory, or corporate research contexts. Avoid confusing 研究 with 勉強 (べんきょう), which means "study" in a more general or school-related sense.

Tips for Learners

  • Use 研究 when referring to systematic or scientific study.
  • Pair it with verbs like する (to do) or 始める (to start) to describe research activities.
  • Remember it is a noun and often appears with の to modify other nouns (e.g., 研究成果).

This word is essential for discussing academic topics and professional investigations in Japanese.
