Amalgamate and disperse are opposites. Amalgamate is to merge several things — especially organizations — into one combined body. Disperse is to spread a gathered crowd, substance or mass out over a wide area until it thins. Amalgamate draws separate things into one; disperse breaks one gathering apart and scatters it wide.
One pulls inward into a single body; the other pushes outward into a thin spread. Amalgamate, from amalgam (a mercury alloy), gathers separate firms or bodies into one whole under a single name. Disperse, from dis- 'apart' and spargere 'to scatter', takes a mass that sits in one place and sends it out across a wide area — a crowd, a cloud of smoke, a head of seeds. Delegates amalgamate into one federation; a crowd is ordered to disperse. One concentrates many into one body; the other thins one body out until it is spread everywhere and nowhere.
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.
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.

Ask which way things are moving. Amalgamate draws separate bodies inward until they stand as one under a single name. Disperse drives one gathering outward until it is spread thin across a wide area — a dandelion head flung the width of a field. If things move together into one whole, that is amalgamate; if a gathering breaks apart and spreads wide, that is disperse.

Amalgamate is transitive and about bodies fusing into one; disperse can be transitive (the wind disperses the smoke) or intransitive (the crowd disperses) and always ends in a wide spread. Note the register gap too: amalgamate is almost always institutional, while disperse ranges from the physics lab to the riot line — its noun even splits into dispersal (the spreading) and dispersion (the physical scattering of light or data).
