Meaning

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.

Examples

1. 「明日10時に集合ね」「りょ」 Let's meet at 10 tomorrow.' 'Ryo.
2. りょ、じゃああとでLINEするわ。 Ryo, I'll LINE you later then.
3. 「これコピーしといて」「りょりょ」 Make copies of this.' 'Ryo ryo.
