急(きゅう)に (kyuu ni)
急に — “suddenly”
Pattern
-
急に + 動詞(変化・出来事)急に変わる / 急に呼ばれる / 急に用事ができる
Where it comes from
It is the に form of the na-adjective 急だ, used as an adverb. It shares a kanji with 急ぐ, but 急に means “suddenly,” not “quickly.”
When to use it
Use it when weather, feelings or plans change unexpectedly: 急に天気が変わりました, 急に用事ができて、行けなくなった. With the passive (呼ばれた) the feeling of surprise is stronger.
Difference from similar words
突然 is a little more formal and common in writing. いきなり is more casual and stronger in surprise. 急に sits between the two and fits either.
Examples
-

-

-

Common mistakes
- 急に does not mean “quickly.” Do not confuse it with 急いで (急いで走る).
- Do not drop the に: 急天気が変わった is wrong.
