millonésimo

Millonésimo is a Spanish word that translates to "millionth" in English. It is an ordinal number representing the position in a sequence that follows the 999,999th item and precedes the 1,000,001st item. In mathematical terms, it signifies the element at the 1,000,000th place.

The word is derived from "millón," which means "million," and the ordinal suffix "-ésimo," indicating the position in a series. It is used in contexts where precise ordering is important, such as in measurements, statistics, or when referring to the one millionth occurrence of an event. For example, one might refer to the "millonésimo" visitor to a website or the "millonésimo" kilogram of a substance.

In Spanish grammar, "millonésimo" is an adjective and agrees in gender and number with the noun it modifies. The masculine singular form is "millonésimo," the feminine singular is "millonésima," the masculine plural is "millonésimos," and the feminine plural is "millonésimas." However, its plural forms are rarely used in practice as ordinal numbers beyond the first few are typically described using cardinal numbers followed by "or" or simply by the cardinal number itself. The concept remains consistent with its English equivalent, signifying the one millionth position in any given quantifiable sequence.
