How it's used
This phrase is used to justify an action taken to avoid a potential negative outcome. It functions as a conjunction or adverbial phrase that signals foresight, often implying that the speaker is being cautious or prudent. Unlike some formal idioms, it is frequently used in casual speech to explain why someone is carrying an extra item or keeping a backup plan.
Examples
Bring an extra jacket out, just in case it gets cold.
