Etymology

The compound 'self-important' is a relatively modern English formation, emerging in the 18th century. It combines the ancient Germanic root for identity, 'self', with the Latinate adjective 'important', which itself derives from the Latin verb importare ("to bring in, imply, be of consequence"). The literal construction suggests one who "imports" or assigns great consequence to oneself. Over time, this literal sense evolved into the modern abstract meaning, carrying a critical connotation of exaggerated and often off-putting personal pride, distinct from mere confidence.
