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

Yes

The word "triunfo" is identical in spelling, meaning, and grammatical function in both Brazilian and Continental Portuguese. The only differences are in pronunciation:

• Vowel Quality: In Brazilian Portuguese, vowels are generally more open and clearly articulated. In Continental Portuguese, unstressed vowels (such as the "i" in "triunfo") tend to be more closed, reduced, or even elided.
• Rhythm: Brazilian Portuguese follows a more syllable-timed rhythm, where each syllable carries a relatively similar weight. Continental Portuguese is more stress-timed, meaning unstressed syllables are shortened significantly, creating a more "clipped" or rapid-fire sound.

Brazilian Portuguese Examples:

1. A conquista do título foi um grande triunfo para o time. (The conquest of the title was a great triumph for the team.)
2. Ele celebrou o triunfo de sua carreira política. (He celebrated the triumph of his political career.)
3. A vitória foi um triunfo da justiça. (The victory was a triumph of justice.)
4. Não foi apenas uma vitória, foi um verdadeiro triunfo pessoal. (It wasn't just a victory; it was a true personal triumph.)
5. O projeto foi um triunfo da equipe de engenharia. (The project was a triumph of the engineering team.)
