Coincide and disperse are opposites in direction. Coincide is for two independent things to occupy the same point or happen at the same time. Disperse is to spread a gathered crowd, substance or mass out over a wide area until it thins. Coincide brings things to one shared point; disperse spreads them out wide.
One brings things to a single point; the other spreads them out over an area. Coincide, from co- 'together' and incidere 'to fall upon', means two things fall on the same spot or moment. Disperse, from dis- 'apart' and spargere 'to scatter', takes a gathered mass and spreads it thin across a wide area. Two events coincide at one moment; a crowd is told to disperse. One converges on a shared point; the other thins out everywhere.
coincide
To coincide is to occupy the same point — in time, space, or opinion — while belonging to different paths. From the Latin co-incidere, 'to fall upon together'. Festivals coincide with full moons; an interview coincides with a strike; two rivals' interests briefly coincide. The word insists on independence: neither schedule bent for the other, which is exactly what makes coincidence feel like fate — two orbits, each obeying only itself, agreeing on a single moment.
disperse
To disperse is to break up a gathering and spread it out until it thins away — movement from concentration to diffusion. A crowd disperses when a concert ends; wind disperses seeds and smoke; light disperses through a prism. The word works both ways — things disperse on their own or are dispersed by some force — but it leans toward an even, gradual spreading that often fades to nothing, rather than a sudden, random fling. What was massed in one place ends up thinly distributed across many.
| coincide | disperse | |
|---|---|---|
| Meaning | occupy the same point or time | spread out over a wide area |
| Direction | to one shared point | outward, over an area |
| The result | two things meeting at a point | a wide, thin spread |
| Often with | dates, events, lines, opinions | crowds, smoke, seeds, light |
| Noun | coincidence | dispersal / dispersion |
| Example | The dates coincide. | The crowd dispersed. |
Ask whether things meet at one point or spread wide. Coincide brings two things to the very same point or moment — two rings crossing at one spot. Disperse spreads a gathering out over a wide area — a dandelion head flung the width of a field. If two things share a single point, they coincide; if a gathering spreads out wide, that is disperse.
coincide
- iHer visit happened to coincide with the festival.
- iiThe two lines coincide at exactly one point.
- iiiOur views on the matter largely coincide.
disperse
- iPolice moved in to disperse the crowd before nightfall.
- iiThe morning wind dispersed the last of the smoke.
- iiiWind and birds disperse the seeds far from the parent plant.
Coincide brings two things to a single shared point or moment; disperse spreads many things out over a wide area. They oppose in direction — toward one point versus away over an area. Coincide's figurative sense (opinions coincide = agree) has no match in disperse.
