Meaning and Usage

The word 濫用 (らんよう) refers to the abuse or misuse of something, often implying excessive or improper use beyond appropriate limits. It is commonly used in formal contexts such as legal, medical, or social discussions.

Common Contexts

濫用 is frequently used with words like 薬 (medicine/drugs), 権力 (power), and インターネット (internet) to describe harmful or unethical overuse.

Collocations and Patterns

  • 濫用する: to abuse or misuse something
  • 権力の濫用: abuse of power

Nuances and Register

This term carries a negative connotation and is typically used in formal or serious discussions. It is not used for casual or minor overuse but rather for significant or harmful misuse.

Common Learner Mistake

Avoid confusing 濫用 with 過剰使用 (かじょうしよう), which means excessive use but without the strong negative implication of abuse. 濫用 implies unethical or improper use, not just quantity.
