Etymology: Spanish "cuarterón" was a term in the colonial caste systems of Spanish America, where it named the child of a European and a mestizo, meaning a person of about three-quarters European ancestry. The word came from "cuarto," meaning "one-fourth," which descends from Latin "quartus." The "-on" ending is an augmentative-style suffix that turned the number into a noun for a fraction of a population. English borrowed the term in the sense of a person with one African-born or African-descended grandparent, a shift in meaning that reversed the original fractions. In the Spanish system, the word described someone nearly white, while English speakers applied it to someone with one-quarter African ancestry, a usage tied to the racial classifications of the American South and the Caribbean. The word is also a doublet of "cuarteron," a variant spelling that shows the same Spanish source entering English along a second path. Its use has declined sharply, and many now regard it as offensive because it was a tool of racial classification.
