collide

To collide means to come into forceful contact with another person or object, resulting in an impact. We most readily picture this as a physical crash—cars colliding on the highway, planets colliding in space, or two football players colliding during a game: "The two vehicles collided at the intersection."

However, collide isn't limited to tangible objects. It can describe situations where ideas, opinions, or interests clash. A "collision of cultures" happens when different traditions and values come into contact, sometimes creating tension but also providing opportunities for learning. You might say, "Their political views collided," meaning they had fundamentally opposing beliefs that led to conflict.

The word carries a sense of force and often implies disruption or harm. While a gentle meeting is simply a meeting, a forceful one is a collision. A collision can be dramatic—like the clash of two galaxies—or subtle, like the clash of emotions within a person. It suggests that something is disturbed or changed by the impact. So, whether it's metal crashing against metal, ideas battling for dominance, or feelings swirling together, to collide is to come together with force and, often, with noticeable consequences.
