Amass and deplete are opposites that act on a large store. Amass means to gather a great quantity by deliberate effort — you amass a fortune, an army, vast reserves. Deplete means to use up a supply, draining it down faster than it is replaced — you deplete reserves, resources, savings. One heaps a great store up; the other empties it.
Amass fills a store to a great size; deplete drains it away. From massa ('a lump') and deplere ('to un-fill'), they are natural opposites: a dynasty amasses a fortune over generations and a spendthrift heir depletes it in a few years; a nation amasses reserves in good times and depletes them in a crisis. Where one builds a hoard, the other bleeds it dry.
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.
deplete
To deplete is to empty by use — the Latin deplere, 'to un-fill', is the exact mirror of 'replete' and 'complete', which share its root plere, 'to fill'. The word is quietly mathematical: fish stocks, aquifers, savings, and stamina all deplete when the rate of taking outruns the rate of return. Nothing dramatic happens at any single moment — that is depletion's danger; each withdrawal looks exactly like the last one, except that eventually nothing stands behind it.

They are opposites — heap up vs drain down. Amass is the treasure hoard: a great store deliberately piled up, climbing to a vast size (amass a fortune, amass reserves). Deplete is the draining battery: a finite supply used up until it scrapes empty (deplete reserves, deplete resources). If a great store is built up, it is amassed; if a supply is drawn down to nothing, it is depleted.
amass
- iOver decades the family amassed a vast fortune.
- iiThe state amassed huge grain reserves.
- iiiHe amassed power well beyond his office.
deplete
- iThe long siege depleted the city's supplies.
- iiOveruse has depleted the aquifer.
- iiiThe legal fight depleted her savings.
They are antonyms acting on a store: amass builds it to a great size, deplete drains it to empty. The same reserves can be amassed in good years and depleted in bad ones. Amass stresses the deliberate building of bulk; deplete stresses the using-up.
