The modern English word "generosity" derives from the Latin word generōsus, which means "of noble birth," which itself was passed down to English through the Old French word généreux. The Latin stem gener– is the declensional stem of genus, meaning "kin," "clan," "race," or "stock," with the root Indo–European meaning of gen being "to beget." The same root gives us the words genesis, gentry, gender, genital, gentile, genealogy, and genius, among others.
Most recorded English uses of the word "generous" up to and during the Sixteenth Century reflect an aristocratic sense of being of noble lineage or high birth. To be generous was literally a way of complying with nobility."
During the 17th Century, however, the meaning and use of the word began to change. Generosity came increasingly to identify not literal family heritage but a nobility of spirit thought to be associated with high birth— that is, with various admirable qualities that could now vary from person to person, depending not on family history but on whether a person actually possessed the qualities. In this way generosity increasingly came in the 17th Century to signify a variety of traits of character and action historically associated (whether accurately or not) with the ideals of actual nobility: gallantry, courage, strength, richness, gentleness, and fairness. In addition to describing these diverse human qualities, "generous" became a word during this period used to describe fertile land, the strength of animal breeds, abundant provisions of food, vibrancy of colors, the strength of liquor, and the potency of medicine.
Then, during the 18th Century, the meaning of "generosity" continued to evolve in directions denoting the more specific, contemporary meaning of munificence, open–handedness, and liberality in the giving of money and possessions to others. This more specific meaning came to dominate English usage by the 19th Century. Over the last five centuries in the English speaking world, "generosity" developed from being primarily the description of an ascribed status pertaining to the elite nobility to being an achieved mark of admirable personal quality and action capable of being exercised in theory by any person who had learned virtue and noble character (Smith 2009).
