'self-centeredness' originates from the combination of 'self' and 'centered,' where 'self' refers to one's own person and 'centered' implies being focused or concentrated.

'self-centered' evolved from the concept of being 'centered on oneself,' eventually forming the noun 'self-centeredness' to describe the quality.

Initially, it meant 'focused on oneself,' but over time it evolved to imply a negative connotation of excessive self-focus.
