Character Breakdown

Meaning and Usage

"用いる" (もちいる) means "to use" or "to make use of" something, often in a formal or written context. It is more formal than the common verb "使う" (つかう) and is frequently found in academic, technical, or official language.

Common Contexts

This verb is often used when referring to the application of techniques, methods, tools, or specialized language. For example, "最新の技術を用いる" (to use the latest technology) or "専門用語を用いる" (to use specialized terms).

Collocations and Patterns

  • 用いる + 技術/方法/手段: to use technology/method/means
  • 専門用語を用いる: to use technical terms
  • 新しい方法を用いる: to employ a new method

Register and Nuance

"用いる" carries a formal tone and is suitable for written Japanese, presentations, or formal speeches. It is less common in casual conversation where "使う" is preferred.

Common Mistake

Learners sometimes confuse "用いる" with "使う" and use it in casual speech, which can sound overly formal or unnatural. Use "用いる" when you want to sound formal or when writing.
