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

Yes

The word "bonitas" is identical in both Brazilian and Continental Portuguese regarding its spelling, grammar (feminine plural adjective), and meaning (pretty/beautiful). The only difference is in pronunciation:

• Brazilian Portuguese: The vowels are generally more open and the rhythm is "syllable-timed," meaning each syllable is pronounced with more distinct clarity and weight. The "i" is clearly articulated.
• Continental Portuguese: The vowels are more closed and the rhythm is "stress-timed." Unstressed vowels, such as the "i" in bonitas, are often reduced or almost swallowed, making the word sound more clipped and shorter.
