Trinta

Trinta is the Portuguese word for the number thirty. It functions as a cardinal numeral in Brazilian and European Portuguese and is used in counting, dates, ages, amounts, and measurements. In forming numbers beyond thirty, Portuguese typically uses the construction trinta e … (for example, trinta e um, trinta e dois), with agreement in gender when referring to nouns (such as trinta e uma classificando feminine nouns). The word also appears in common expressions involving time, quantity, and ranges, such as trinta minutos (thirty minutes) or trinta e quarenta (thirty to forty).

Etymology and cognates: Trinta derives from the Latin triginta. The form shows typical Iberian Romance development, sharing cognates with Galician trinta and with related forms in other Romance languages, such as Italian trenta and Spanish treinta, which reflect parallel Latin roots with regional phonetic changes.

Usage in context: As a base numeral, trinta is a fundamental building block for numbers in the range of 30 to 39 and participates in arithmetic, calendrical calculations, and scoring systems. In literature and everyday speech, it often serves as a precise, neutral numeral rather than an approximate figure.

Toponymy and references: In Portuguese-speaking regions, numerical terms sometimes appear in place names or historical references, but Trinta is primarily encountered as the number thirty in ordinary language.
