Setenta

Setenta is the Spanish word for the cardinal number 70. It is used in counting, to express quantities, ages, and dates, and is common in references to a decade, as in “los años setenta” (the seventies).

Etymology and cognates: Setenta derives from Latin septuaginta, meaning seventy, and belongs to the Romance language family. Related forms appear in other languages, such as Portuguese setenta and Italian settanta, reflecting the shared Latin origin.

Numerical context: In Roman numerals, 70 is written as LXX. As a figure, setenta is an even, composite number, divisible by 1, 2, 5, 7, 10, 14, 35, and 70. In everyday use, it appears in expressions like “setenta años” (seventy years) or “la década de los setenta” (the 1970s). Ordinal forms to denote seventieth exist in formal or regional variants, but the cardinal form setenta is the standard in most contexts.

Overview: The term serves as a basic building block in Spanish numerals and shares its origin with several other Romance languages. Its usage spans daily counting, historical dating, and cultural references to specific decades.
