Know-it-all 🧠🌎💯

Meaning

A person who acts as if they possess superior knowledge on every subject and frequently corrects or condescends to others.

Origin

The phrase “know-it-all” burst onto the American linguistic scene in the early 20th century, a time when rapid industrialization and burgeoning educational opportunities meant that people were encountering more individuals eager to parade their supposed expertise. Before this, concepts like "wiseacre" or "pedant" had their place, but "know-it-all" captured a particular blend of unearned confidence and unsolicited advice that resonated deeply. It was coined to succinctly label that irritating personality type who, despite their confident pronouncements, often proved more annoying than truly insightful, becoming an instant, popular shorthand for intellectual pretension and social exasperation.
