Ducentésimo

Ducentésimo is an ordinal numeral meaning "the two hundredth." It designates the position of an element in an ordered sequence, specifically the place number 200. The term is used in several Romance languages to express the ordinal associated with the cardinal two hundred, including Portuguese and Spanish, where it takes the form ducentésimo. In Italian the equivalent is ducentesimo. The word derives from the Latin ducentēsimus, built from ducentī "two hundred" plus the standard ordinal suffix -ēsimus, which in the modern languages has become -ésimo or -esimo.

In usage, ducentésimo appears in contexts such as counting items, enumerating days, or indexing positions in a list. For example, in Spanish one might say “el ducentésimo día del año” to mean “the two hundredth day of the year,” or in Portuguese “o ducentésimo dia do ano.” In Italian, one would say “il ducentesimo giorno dell’anno.” The form is somewhat formal or technical and is less common in everyday speech, where simpler ordinals like centésimo (hundredth) or numbers written in digits are more typical.

Related terms include centésimo (hundredth) and milésimo (thousandth), which follow the same pattern for other base numbers. The concept of ducentésimo is primarily linguistic and mathematical, used to describe position within an ordered sequence or to denote a specific ordinal rank in lists, calendars, or scholarly texts.
