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

Yes

The spelling, meaning, and grammatical identity of the word "roupas" (the plural form of the noun roupa) are identical in both Brazilian and Continental Portuguese. However, there are differences in how the word is pronounced and how it is used within the context of a sentence.

• Pronunciation: In most regions of Brazil, the "s" at the end of "roupas" is pronounced as a sibilant [s]. In Portugal, the "s" is almost always pronounced as a "sh" sound [ʃ]. Additionally, Brazilian Portuguese tends to have more open vowels, while Continental Portuguese often features more closed or reduced vowel sounds.
• Usage and Syntax: While the word "roupas" does not change, the words surrounding it do. In Portugal, it is standard to use a definite article before possessive pronouns (e.g., "as minhas roupas"), whereas, in Brazil, this article is frequently omitted (e.g., "minhas roupas"). Furthermore, a Portuguese person would typically use the pronoun "tu" (and its corresponding verb forms) to refer to "your clothes," whereas a Brazilian would more likely use "você" (and "suas roupas").
