The History of the Word

Foundation originated as a late fourteenth-century word, meaning “the action of foundation.” This is derived from the Old French word fondacion from the fourteenth century, and it also has roots in the Late Latin word fundationem (the nominative would be fundatio), which means “a founding.” Some specialized senses of the word, including “an establishment of an institution that supports it” or “the physical building blocks of a structure,” also emerged in the late fourteenth century. Another meaning, “that which is founded,” such as a university or hospital, comes from the early 1500’s. During the same time period, another meaning developed—“funds endowed for benevolence or charity.”
