未読スルー

• 読み: みどくスルー
• ローマ字: midoku surū
• 漢字の分解: 未 (not yet) + 読 (read) + スルー (through/ignore) → not even reading the message
• 発音: /mi.do.ku su.rūː/

意味

Intentionally not opening a message to avoid showing a read receipt — a step beyond leaving someone on read.

While 既読スルー means reading a message but not replying, 未読スルー takes avoidance further by not even opening the message. This way, no read receipt is generated and the sender does not know if the message was seen. It is considered a more deliberate form of ignoring someone, and can feel even more hurtful than 既読スルー because it signals complete disinterest. Very common in LINE culture where read receipts are prominent.

例文

1. 通知で内容見えたけど、めんどいから未読スルーした。
2. 未読スルーされてるっぽい、既読もつかない。
3. あの人いつも未読スルーするから連絡しても無駄。

正しい言い方

避ける言い方

• 未読スルーを深刻に受け止めすぎる (Don't take unread-ignoring too seriously — they might just be genuinely busy)

よくある間違い

• Confusing 未読スルー with 既読スルー — 未読 means the message was not even opened, 既読 means it was read but not replied to
