How it's used
This idiom is used to describe an event that occurs with such extreme speed that it is impossible to prepare for or defend against. It is often employed in contexts involving sudden accidents, unexpected news, or lightning-fast physical actions. While it originates from classical literature, it remains a common and effective way to emphasize the sheer velocity of an occurrence in modern speech.
Examples
His movements were so fast that I couldn't react at all.
This happened so suddenly that everyone was shocked.

Common mistake
Learners often mistake this for a simple adjective, but it functions as an adverbial phrase describing the manner in which an action occurs. It is typically used with verbs of movement or occurrence rather than to describe a person's general personality.
