Etymology: "Decumulation" is built from the prefix "de-" (meaning reversal or removal) attached to "accumulation," which itself comes from Latin "accumulare," "to heap up," from "ad-" plus "cumulus," meaning "heap" or "pile." So the word literally means "un-heaping," the undoing of a pile that was built up over time. The term is a modern formation, not an ancient one. Its use in English is most common in finance, where it describes the phase of retirement or investment when a person begins drawing down savings rather than adding to them, and it has since spread to ecology and resource management. Because "accumulation" was coined for the building up of wealth, "decumulation" is the mirror term for spending it down, a pairing that makes the vocabulary of saving and spending read as a single process in reverse.
