Description
- by chance
- by accident
- without planning
Sometimes life throws you little surprises—moments when things line up in an unexpected way. That's when we say something happened "coincidentally." It means two or more things came together by chance, not because of planning or a clear cause-and-effect link. Imagine running into a childhood friend while on vacation across the country—you both happened to be in the same place at the same time by chance!
The word comes from "coincidence," the state of events happening together. "Coincidentally" adds a sense of surprise to that overlap. It's more than two things happening; it's two things happening in a way that feels unexpected.
"Coincidentally" describes something that happens by chance, without any deliberate planning or direct connection between events. It suggests an accidental alignment of circumstances and can make an outcome feel surprising or noteworthy. For example: "I was just thinking about my old college roommate, and coincidentally, she called me five minutes later!"
The key to understanding "coincidentally" is recognizing the lack of causation. If you study hard for a test and get a good grade, that's not coincidental—it's a result of your effort. But if you randomly pick a set of numbers and they match the winning lottery draw, that is pure chance.
It's often used to introduce an unexpected link or a surprising turn of events in a story or conversation. "Coincidentally, both my parents and grandparents met at the same summer camp." It can feel like a happy accident.
Overall, "coincidentally" signals that something happened in an unplanned, unconnected way—a small twist that can make life feel surprising.
