承知しました
Meaning
A very formal way of saying 'acknowledged' or 'understood' — sometimes used ironically in casual texting for humorous effect.
承知しました is genuinely formal Japanese meaning 'I have understood/acknowledged.' In texting culture, it has a dual life: used sincerely in work-related messaging (business LINE, Slack, email) and used ironically among friends to add formality humor. When a friend asks you to buy milk and you reply 承知しました, the joke is the exaggerated politeness. The ironic usage highlights the gap between formal business Japanese and casual friend communication.
Examples
- はい、承知しました。明日の会議、準備しておきます。 Yes, understood. I will prepare for tomorrow's meeting.
- 「コンビニでアイス買ってきて」「承知しました」 Go buy me ice cream from the convenience store.' 'Acknowledged.
- 承知しました、ただちに対応いたします（笑） Understood, I shall attend to it immediately (lol).
