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

Yes

The word "país" is identical in meaning, spelling, and grammatical function in both Brazilian and Continental Portuguese. The only difference lies in pronunciation:

• The "s" sound: In Brazilian Portuguese, the "s" at the end of the word is typically pronounced as a sibilant /s/ (like the "s" in "sun"). In Continental Portuguese, the "s" is pronounced as a palatal fricative /ʃ/ (like the "sh" in "shoe").
• Vowel quality and rhythm: Brazilian Portuguese tends to have more open vowels and a more melodic, rhythmic cadence. In contrast, Continental Portuguese often features more closed or reduced vowels and a more "clipped" or consonant-heavy rhythm.
