浪費

• 読み: ろうひ
• ローマ字: rohi
• 漢字の分解: 浪 (waves, wandering) + 費 (expense, spending) → money drifting away; wasteful spending
• 発音: /ɾoː.çi/

意味

Wasteful spending; squandering money on things of little value.

Unlike 散財 which can be fun, 浪費 carries a more critical, negative tone — it implies the money was truly wasted with nothing worthwhile to show for it. It's commonly used in self-criticism or when lecturing others about poor spending habits. Financial advice content frequently uses this word as something to avoid.

例文

1. コンビニで毎日なんとなく買い物するの、積み重なると浪費だよね。
2. 浪費癖を直したくて家計簿アプリ入れたのに三日坊主で終わった。
3. セール品ばっかり買うのも、使わないなら浪費と同じだよ。
