prueban

Prueban is the third-person plural present indicative form of probar, a Spanish verb with several related meanings, including to try, to taste, to test, and to prove. The form is used with subjects such as ellos, ellas, or ustedes and corresponds to "they try," "they test," or "they prove" in English, depending on context.

Probar is an o-ue stem-changing verb in the present tense. The full present-conjugation is pruebo, pruebas, prueba, probamos, probáis, prueban. The stem changes to prue- in most forms, while the nosotros form remains probamos and the vosotros form is probáis.

Usage: Prueban appears in contexts such as testing software, tasting foods, or validating a hypothesis. Examples: Ellos prueban el nuevo software para verificar su funcionamiento. Los científicos prueban la hipótesis mediante experimentos. La empresa prueba el producto en varios mercados. La evidencia prueba su culpabilidad. In Spain, the vosotros form probáis is used; in much of Latin America, ustedes prueban is standard.

Etymology and regional variation: Probar comes from Latin probare, meaning to test or prove. The present tense form prueban reflects the standard Spanish pattern of stem change, with regional variation mainly in the form used for the plural second person (vosotros) in Spain versus ustedes in Latin America.
