Explanation

Amassed is the past form of amass, which means to gather a lot of something over time. You don’t get it all at once—you collect, save, or bring it together bit by bit until it becomes a large amount. People can have amassed money by saving, amassed books by collecting them, or amassed experience by working many years. It suggests steady effort, patience, or growth. When we say “He amassed a fortune,” we mean he built it up slowly, not in one day.
