The word "egoist" derives from the Latin "ego," meaning "I," reflecting its core focus on the self. The suffix "-ist" (from Greek "-istes") denotes a person who practices or adheres to a particular philosophy or behavior. Combined, "egoist" literally means "one who prioritizes the self," aligning with its modern usage in both everyday language (self-centeredness) and philosophy (ethical egoism). The term emerged in the 18th century, influenced by Enlightenment debates on individualism.
