What does amass mean?
"Amass" is a verb meaning to gather together or accumulate a large quantity of something over time, most often money, wealth, possessions, or information. To amass a fortune is to build it gradually through repeated acquisition, and the word implies considerable scale — small amounts are not typically described as amassed. The verb can also apply to intangible things such as power, influence, evidence, or data, and occasionally to the physical assembly of people or forces, as when a leader amasses troops. Connotations vary with context: amassing wealth through diligent saving sounds admirable, while amassing riches through exploitation may sound greedy. Derived from the same Latin root as "mass," the word literally suggests heaping things into a growing pile. It remains a staple of financial journalism, biography, and everyday speech about accumulation, making it a precise and vivid alternative to plainer verbs like "get" or "collect."

Where does amass come from?
"Amass" derives from the French verb "amasser," meaning to heap together, which itself traces back to the Latin "massa," meaning a lump or mass, ultimately from Greek "maza," a barley cake or lump of dough. The word entered English in the late sixteenth or early seventeenth century, carrying with it the image of piling material into an ever-larger heap. Its cognates include "mass" itself and related words built on the same Latin root, all sharing the core idea of accumulated bulk.
