high-iq

The term is a modern compound adjective formed in the 20th century from the English adjective "high," with roots in Proto-Germanic hauhaz and ultimately Proto-Indo-European kewk-, conveying the sense of being elevated or great. It is combined with the initialism "IQ," an abbreviation for "Intelligence Quotient," a concept coined by the German psychologist William Stern in 1912. The literal construction "high-IQ" therefore logically denotes a person whose measured intelligence quotient is elevated above the average, directly linking the ancient concept of physical height to a modern metric of cognitive ability. This compound exemplifies how contemporary technical terminology is often built from simple, native English lexical elements.
