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

Yes

The word "sonhávamos" is identical in spelling, meaning, and grammar in both Brazilian and Continental Portuguese. It is the first-person plural (nós) of the imperfect indicative of the verb sonhar (to dream). The only differences are in pronunciation:

• Vowel Reduction: In Continental Portuguese, unstressed vowels (such as the "o" in sonh) are more heavily reduced or "closed," whereas in Brazilian Portuguese, they remain more open and distinct.
• Rhythm: Brazilian Portuguese features a more "syllable-timed" rhythm, making the word sound more melodic, while Continental Portuguese is "stress-timed," often resulting in a faster, more clipped pronunciation of the unstressed syllables.
