りょ

• 読み: りょ
• ローマ字: ryo
• 発音: /ɾjo/

意味

Ultra-short abbreviation of 了解 (ryōkai, 'understood/roger that'), used in text messages to quickly acknowledge something.

りょ is the most abbreviated form of 了解 (understood), which itself is already a casual response. The abbreviation chain goes: 了解しました → 了解 → りょうかい → りょ. Some people even shorten it further to just り. It is used exclusively in text communication and conveys a laid-back, efficient response style. Using it with people you are not close to can come across as too casual or dismissive.

例文

1. 「明日10時に集合ね」「りょ」
2. りょ、じゃああとでLINEするわ。
3. 「これコピーしといて」「りょりょ」
