Character Breakdown

Meaning and Usage

"荒らす" (あらす) is a verb that means to damage, ruin, or mess up something. It often implies causing disorder or destruction, whether physically (like a storm damaging a field) or metaphorically (like messing up a room or disrupting an online forum).

Common Contexts

It is frequently used to describe natural disasters damaging land or crops, children or people making a place messy, and disruptive behavior online or in social settings.

Collocations and Patterns

  • 畑を荒らす: to damage fields, often by natural causes
  • 部屋を荒らす: to mess up a room, usually by people
  • 掲示板を荒らす: to troll or disrupt an online forum

Register and Nuance

The word is neutral but can carry a negative nuance because it describes unwanted damage or disorder. It is commonly used in both formal and informal contexts.

Common Mistakes

Learners sometimes confuse "荒らす" with "壊す" (こわす), which means "to break." "荒らす" emphasizes disorder and messiness, not just breaking something physically. Use "荒らす" when the focus is on ruining or messing up an area or system rather than just breaking an object.
