Character Breakdown

Meaning and Usage

"微量" (びりょう) refers to an extremely small or minuscule amount of something, often used in scientific, medical, or technical contexts. It emphasizes that the quantity is so small it might be barely noticeable but still significant.

Common Contexts

You will often see "微量" used when discussing substances like chemicals, medicines, or elements where even a tiny amount can have an effect. For example, "微量元素" means trace elements essential for health.

Collocations and Patterns

  • 微量の + noun: indicates a tiny amount of something (e.g., 微量の水分 - a tiny amount of moisture).
  • 微量でも + verb: expresses that even a minuscule amount is sufficient for some effect (e.g., 微量でも効果がある - effective even in tiny amounts).

Register and Nuance

"微量" is a formal term often found in written language, scientific papers, or technical discussions. It is less common in casual conversation but may appear when discussing precise measurements.

Common Learner Mistake

Learners sometimes confuse "微量" with "少量" (しょうりょう), which means "small amount" but is less extreme. Remember, "微量" implies an extremely tiny quantity, often near the detection limit, while "少量" is simply a small but noticeable amount.
