アラフィフ

• 読み: アラフィフ
• ローマ字: arafifu
• 漢字の分解: From アラウンド (around) + フィフティ (fifty) → abbreviated to アラフィフ
• 発音: /a.ɾa.ɸi.ɸu/

意味

Around fifty years old — describing someone in their late 40s to early 50s.

アラフィフ follows the same pattern as アラサー (around thirty) and アラフォー (around forty), describing people approximately 50 years old (roughly 47-53). The term is often used in lifestyle media, fashion, and health contexts targeting this demographic. While originally coined by media, it has become a common self-identifier. The term is typically used with neutral to positive connotations, as 'active fifties' becomes an aspirational lifestyle category.

例文

1. アラフィフでもおしゃれな人増えたよね。
2. うちの母、アラフィフなのにめっちゃ元気。
3. アラフィフ向けのファッション雑誌って結構あるよね。
