✔ Out of the blue
■ Meaning: If something happens out of the blue, you’re not expecting it to happen and you’re surprised when it does.
■ For example:
- A letter came today, totally out of the blue, from a lawyer who said that an uncle I hadn’t heard from in years had died and left me a million dollars. But then my alarm went off … and I woke up.
- A girl Barry had known years ago called him out of the blue and invited him to her wedding. He was very surprised, as you can imagine.
