散乱物(さんらんぶつ)

Compound of 散乱(さんらん) ('scattering; being strewn about') and 物(ぶつ) ('thing; object'). A formal, written term used in road traffic information, news reports, and public-safety contexts. Less common in casual conversation, where speakers prefer phrases like 散(ち)らかった物(もの) or just ごみ ('litter; rubbish').

Usage

• Often appears in expressway and highway traffic alerts: 散乱物(さんらんぶつ)あり ('debris reported'), warning drivers of fallen cargo or accident debris.
• The companion verb 散乱(さんらん)する ('to be scattered') is common; 散乱物(さんらんぶつ) packages the result of that scattering as a noun.
• Distinct from 'wreckage' of a vehicle (残骸(ざんがい)); 散乱物(さんらんぶつ) emphasises that the items are spread out over an area.
