Simple:
* The two projects are running concurrently, meaning they happen at the same time.
* The defendant was sentenced to two concurrent terms of imprisonment.
More Complex:
* The development team is working on concurrent features, allowing for faster progress on the overall project.
* The historian argued that the two revolutions were not concurrent, but rather one followed directly from the other.
* The professor's research interests are concurrent with those of the department, making for a good fit.
Remember: "Concurrent" means happening at the same time. You can use it to describe actions, events, or even thoughts that happen simultaneously.
