self-importance

The compound 'self-importance' is a relatively modern English formation, synthesizing two distinct lexical streams to articulate a psychological concept. The Germanic root 'self,' with ancient Proto-Indo-European origins meaning "of oneself," provides the reflexive element, anchoring the quality to the individual's own perception. The Latinate component 'importance' evolved from a concrete meaning of "bearing consequence" (literally, "that which is brought in") to an abstract sense of significance or weight. By the 18th century, these elements fused to create a term that literally means "the state of attributing great significance to oneself," capturing the essence of an inflated ego with logical precision, where the self is the object of its own overstated valuation.

Structure: self (own) + importance (significance) - self: From Old English self, seolf, sylf, meaning "one's own person." It is a Germanic root, functioning as a pronoun or prefix denoting identity or autonomy. - importance: From Medieval Latin importantia, meaning "significance, weight." The morpheme 'import' (from Latin importare, "to bring in, signify") is combined with the noun-forming suffix '-ance' (from Latin -antia), indicating a state or quality.
