buena

Buena is the feminine singular form of the Spanish adjective bueno, meaning good. It is used to describe feminine nouns or feminine subjects and agrees in gender with the noun it modifies. The masculine form is bueno, and the corresponding plural forms are buenos (masculine) and buenas (feminine).

Etymologically, buena derives from the Latin bonus, and it functions as an adjective in modern Spanish. It is used in a wide range of expressions, such as buena idea (a good idea), buena persona (a good person), buena suerte (good luck), and buena noticia (good news). In contrast to bien, which is used as an adverb or neuter concept, buena marks gender and number to agree with the noun.

In colloquial speech, buena can also appear as an interjection to express approval or praise, for example, ¡Buena! or ¡Buena jugada!, especially in sports or competitions, where it signals that a move or outcome was well done.

Geographically, buena occurs as a component in many place names across the Spanish-speaking world and regions influenced by Spanish. It commonly appears in compounds such as Buena Vista or Buena Park, where the element conveys a positive or favorable descriptor of the place. Such toponyms reflect historical naming practices rather than grammatical usage.
