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

Yes

The word "enfermeiros" is identical in spelling, meaning, and grammatical function in both Brazilian and Continental Portuguese. The differences are strictly phonetic:

• Vowel Reduction: In Continental Portuguese, unstressed vowels often undergo reduction. The "e" in the middle of the word (enfermeiros) may be whispered or almost disappear, making the word sound more like "enfrmeiros." In Brazilian Portuguese, vowels are generally more open and clearly articulated.
• Sibilance: In most regions of Portugal, the "s" at the end of the word is pronounced as a "sh" sound (/ʃ/). In many parts of Brazil, particularly in the interior, it is pronounced as a sharp "s" sound (/s/), though in coastal cities like Rio de Janeiro, it may also take on a "sh" sound.
