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

Yes

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

• Brazilian Portuguese: The vowels are generally more open, and the rhythm is "syllable-timed," meaning each syllable receives a more distinct and melodic emphasis.
• Continental Portuguese: The vowels are more closed, and the rhythm is "stress-timed." In this version, unstressed syllables are often reduced or "swallowed," making the word sound more clipped or staccato.
