uní

Uní is the first-person singular preterite form of the Spanish verb unir, meaning I joined or I united. It denotes a completed action in the past, typically describing the act of bringing together two or more elements, such as pieces, groups, or ideas. In narrative writing, uní appears to recount past events, for example: “Ayer uní las piezas del rompecabezas” (Yesterday I joined the puzzle pieces).

Grammar and usage notes: Unir follows a regular -ir verb pattern in the preterite, with yo form uní and other forms such as tú uniste, él unió, nosotros unimos, vosotros unisteis, ellos unieron. The third-person singular form unió is often confused with uní due to the accent, but it refers to “he/she/it joined.” The word uní can also appear in composite verb constructions or reported speech to indicate a past act of joining.

Etymology and related forms: Unir derives from Latin unire, meaning to unite. Related Spanish terms include unión (noun, “union”) and unir, as well as unirse (reflexive form, “to join oneself”). The accent in uní helps indicate the correct pronunciation and distinguishes it from other conjugations.

Other uses and disambiguation: In isolation, uní is primarily a grammatical form rather than a standalone term or name. In some contexts, uppercase variants or similar-looking acronyms (for example, UNI or UNÍ in signage or branding) may refer to institutions or organizations, but uní as a common noun or verb form remains the grammatical past-tense form of unir.
