The word "self-interest" combines "self," derived from Old English "self" (meaning "one's own person"), and "interest," from Latin "interest" (originally "it concerns, it makes a difference"). The term emerged in the 17th century to describe the prioritization of personal gain, reflecting Enlightenment-era debates about human motivation. The morphemes retain their original meanings, with "self" emphasizing individuality and "interest" denoting stake or advantage.
