primeiros

Primeiros is the Portuguese term meaning "the first ones." It is the masculine plural form of the adjective primeiro and is used to refer to the earliest members of a group or the initial items in a sequence. As an adjective, primeiros agrees with the noun it modifies; the feminine plural is primeiras. When used as a noun phrase, it is typically introduced by an article, as in os primeiros or os primeiros a chegar.

In everyday and formal Portuguese, primeiros appears in descriptions of chronology, history, or process: os primeiros habitantes do território (the earliest inhabitants of the territory); os primeiros passos (the first steps). It can also be used metaphorically to denote pioneers or early adopters, such as os primeiros a experimentar a nova tecnologia.

In literature and education, primeiros is often encountered as part of fixed expressions or as a heading, such as Primeiros, Primeiros momentos, or Primeiros passos, to mark initial sections. There is no widely recognized standalone entity or proper noun simply named "Primeiros" on its own; rather, it functions as a common linguistic element. The concept has direct equivalents in other Romance languages, and its usage aligns with the general grammar of adjectives and noun phrases in Portuguese.
