How it's used
Literary in origin, this phrase is frequently used in news reports or dramatic storytelling to emphasize the suddenness of a drastic change. It carries a sense of gravity or surprise that simple time expressions lack. While it literally refers to a single night, it is almost always applied to abstract concepts like status, wealth, or physical landscapes rather than literal sleep cycles.
Examples
His shop went out of business overnight.
Why has this place changed so much overnight?

Common phrases
to become famous overnight
to disappear overnight
Common mistake
Avoid using this to describe literal events that happen while someone is sleeping, such as waking up with a cold. It is reserved for significant, often irreversible shifts in circumstances.
