サブ垢

• 読み: サブあか
• ローマ字: sabu aka
• 漢字の分解: サブ (sabu, from English 'sub') + 垢 (aka, account) → sub account
• 発音: /sa.bu.a.ka/

意味

A secondary or sub account used alongside one's main account, often dedicated to specific interests or communities.

A compound of サブ (sabu, from English 'sub') and 垢 (aka, 'account'). Unlike 裏垢 (which is secret), a サブ垢 is generally known to friends and is used to separate different interests — for example, one account for daily life and another for a specific fandom. Many Japanese users maintain サブ垢 to avoid overwhelming their main followers with niche content.

例文

1. サブ垢は趣味用に使い分けてる。

3. アカウント分けたくてサブ垢作った。
