Assure vs Ensure (What’s the Difference?)

“Assure” and “Ensure” are often used interchangeably but have distinct meanings. “Assure” involves giving confidence or dispelling doubts, often focusing on people and their feelings. For instance, one might assure a friend of their success.

In contrast, “Ensure” means to make certain that something will happen or be achieved. It focuses on outcomes or events, like ensuring a project’s completion on time. Understanding these differences can enhance clarity and precision in communication.
