たちまち

• 読み: たちまち
• ローマ字: tachimachi
• 漢字の分解: 忽 (kotsu) — sudden, fleeting (kanji form 忽ち is rarely used)
• 発音: /ta.tɕi.ma.tɕi/

意味

In an instant; immediately; right away; at once. Describes extremely rapid change.

An adverb emphasising how quickly something happens, often with a sense of surprise at the speed. Unlike すぐに (right away), たちまち implies a dramatic or noteworthy transformation: たちまち人気になった (became popular in no time), たちまち売り切れた (sold out instantly). Slightly literary in tone.
