Amalgamate and coincide are only loosely related, and rarely interchangeable. Amalgamate is to merge several things — especially organizations — into one combined body. Coincide is for two independent things to occupy the same point or happen at the same time, often by chance. Amalgamate fuses things into one; coincide simply has them meet at a shared point without merging.
Both bring things to one point, but only one of them makes a single thing. Amalgamate, from amalgam (a mercury alloy), merges separate bodies into one whole under a single name. Coincide, from co- 'together' and incidere 'to fall upon', means two things fall on the same spot or moment while staying separate — two dates that happen to land together, two lines that cross at a point. Two firms amalgamate into one company; two events coincide but remain two. One yields a single body; the other only a shared point.
amalgamate
To amalgamate is to combine several distinct things into a single larger whole — most often companies, institutions, or groups. The word comes from amalgam, an alloy of mercury with another metal, and it keeps that flavour: the parts bond into one body but often stay recognizable within it, the way stones stay visible in a wall. When firms amalgamate they dissolve into a new combined entity. It is a formal word, a close cousin of merge and consolidate, and the quiet opposite of forces that disperse.
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.
| amalgamate | coincide | |
|---|---|---|
| Meaning | merge several organizations into one | occupy the same point or time |
| The result | one combined body | two things sharing a point, still separate |
| Register | formal, institutional | neutral, often formal or technical |
| Often with | companies, councils, unions | dates, events, lines, opinions |
| Noun | amalgamation | coincidence |
| Example | The firms amalgamated. | The dates coincide. |
Ask whether one thing results, or two things merely touch. Amalgamate makes a single body out of several — firms fused under one name. Coincide leaves the things separate; they only share a point in space or time, like two rings that cross at one spot and part again. If several become one, that is amalgamate; if two independent things merely meet at a shared point, they coincide.
amalgamate
- iThe two authorities amalgamated into a single council.
- iiSeveral small firms amalgamated under one brand.
- iiiThe libraries amalgamated their catalogues.
coincide
- iHer visit happened to coincide with the festival.
- iiThe two lines coincide at exactly one point.
- iiiOur views on the matter largely coincide.
These are not true synonyms: amalgamate makes one thing from several, while coincide leaves things separate but sharing a point or moment. They meet only in the loose sense of 'coming together'. Note coincide's figurative use — when opinions coincide, they agree — which amalgamate never carries; and 'coincidence' usually means a chance meeting of events, not a merger.
