Definition in Spanish

Apócope del número 'uno' que actúa como artículo indefinido delante de sustantivos masculinos singulares para expresar una unidad indeterminada, conservándose ante algunos femeninos por motivos.

Word origin

It comes from Latin unus, with the numeral uno losing its final -o by apocope in pre-nominal position to produce un as the indefinite article.

Usage tips

  • It also appears before some feminine nouns that begin with a stressed a (agua, águila, hacha), but the noun remains feminine so adjectives agree in the feminine.
