trescientos

Trescientos is the Spanish cardinal number that denotes the value 300. It functions as an adjective before masculine plural nouns, as in trescientos libros, and its feminine form, trescientas, accompanies feminine plural nouns, as in trescientas personas. When used in isolation or in enumerations, trescientos can also stand as a numeral by itself.

Etymology and form: The word derives from tres (three) plus cientos (hundreds), from Latin trecenti, which itself comes from centum (hundred). It is part of the regular pattern of Spanish hundreds, alongside doscientos, cuatrocientos, quinientos, and so on. In numbers combining hundreds with tens and units, the form remains trescientos: 342 is trescientos cuarenta y dos, and 301 is trescientos uno. For exact hundreds, the predicate form is trescientos used with masculine nouns, or trescientas with feminine nouns.

Usage: Trescientos appears commonly in dates, quantities, prices, distances, and measurements. Examples include trescientos euros, trescientos kilómetros, and trescientos años. In Roman numerals, the value 300 is represented as CCC.
