Amass and disperse are opposites of concentration. Amass means to gather a great quantity into one place by deliberate effort — a fortune, an army, vast holdings. Disperse means to scatter a mass in different directions — a crowd disperses, seeds disperse, holdings are dispersed. One concentrates a great deal; the other breaks it up and spreads it.
Amass draws a large quantity together; disperse drives it apart. From massa ('a lump') and a Latin root for scattering, they reverse each other: a collector amasses a great holding, and on their death it is dispersed among buyers; an army is amassed at the border and dispersed once the threat passes. Where one gathers into a dense mass, the other scatters it wide.
amass
To amass is to gather a great quantity on purpose — a fortune, an army, a vast collection, power. Where things accumulate almost on their own and you gather whatever is to hand, to amass is to build up a large amount through deliberate effort, with the emphasis on sheer size. It often carries a tint of ambition or greed: people amass wealth, regimes amass weapons. From the Latin massa, 'a lump', what you amass ends up a substantial, weighty whole.
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.

They are opposites — concentrate vs scatter. Amass is the treasure hoard: a great quantity gathered into one dense place (amass a fortune, amass an army). Disperse is the dandelion: a mass broken apart and scattered in all directions (a crowd disperses, a collection is dispersed). If a great deal is drawn into one place, it is amassed; if a mass is broken up and spread, it is dispersed.

They are antonyms: amass concentrates a great quantity in one place; disperse breaks that mass apart and scatters it. A famous collection is amassed by one person and later dispersed among many. Amass gathers into a dense whole; disperse spreads it wide.
