self-focused

The word "self-focused" is a modern English compound adjective. Its first element, "self," is an ancient Germanic root referring to one's own identity. The second element, "focus," originates from the Latin word for "hearth" or "fireplace," the central gathering point in a Roman home. By the 17th century, "focus" was adopted into scientific terminology to denote the point where rays of light converge. The suffix "-ed" is added to the noun "focus" to create an adjectival form. Thus, the literal construction "having one's own center" evolved to describe a person predominantly oriented toward their own concerns or, in a technical sense, an optical device that centers an image automatically.
