Wealth

The word traces to the Middle English welthe, meaning "happiness, prosperity, well-being," formed from wele ("well-being") with the suffix -th, on the pattern of health from heal.1 The Old English root wela meant "prosperity, riches, possessions" and also "well-being, bliss." It descends from the Proto-Germanic *welo-, from the same root that gives us "well."

In its earliest English usage, wealth encompassed the full range of human flourishing, not only material possessions but physical health, emotional contentment, and social standing. The "commonwealth," a political term that entered English in the fifteenth century, originally meant the common well-being of the whole community, not a collection of states.2

The narrowing of wealth to mean primarily financial assets and material abundance was gradual. By the sixteenth century, the word was shifting toward its modern sense of "abundance of possessions."3 Adam Smith's An Inquiry into the Nature and Causes of the Wealth of Nations (1776) cemented the economic meaning, though Smith himself argued that the real wealth of a nation was its annual labor, not its gold reserves.4

The older, broader sense survives in phrases like "a wealth of experience" and "a wealth of knowledge," where the word still means abundance in the original, non-monetary sense. In Old English, a person of great wela was someone whose life was going well, not necessarily someone with a large account balance.5
