Is the word prova the same in Brazilian and European Portuguese?

No. While the spelling and fundamental meaning of "prova" are identical in both dialects, there are differences in typical usage and contextual preference. In Portugal, the word is often used for specific components of an assessment, whereas "exame" is more common for major final exams. Additionally, when referring to trying on clothing, Brazilians typically use the plural "prova de roupas," while Portuguese people more naturally use the singular "prova de roupa."
