Expert writing Tips

Best practice

Use "it was out of the blue" to emphasize the unexpected nature of an event, especially when the lack of anticipation is central to the narrative. For example: "The job offer came completely out of the blue, as I hadn't applied anywhere recently."

Common error

Avoid using "it was out of the blue" for events that are reasonably foreseeable or part of a known process. Overusing it in such situations diminishes its impact. For instance, stating "The tax bill arrived out of the blue" is inaccurate, as tax bills are expected annually.
