The word "self-centered" combines "self" (Old English "self," meaning "one's own person") and "center" (Latin "centrum," via Old French "centre," meaning "middle point"). The suffix "-ed" turns it into an adjective. The term emerged in the early 19th century to describe someone whose focus revolves entirely around themselves, metaphorically placing their own ego at the "center" of their world.
