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

Yes

The word "parar" retains the same meaning, spelling, and grammatical function in both Brazilian and Continental Portuguese. The only differences lie in pronunciation:

• Vowels: In Brazilian Portuguese, vowels are generally more open and clearly articulated. In Continental Portuguese, vowels are much more "reduced" or closed, often sounding almost swallowed when unstressed.
• The "r" sound: In many regions of Brazil, the final "r" in "parar" is pronounced as a soft breathy sound (like an "h" in English) or a glottal fricative. In Portugal, the "r" is typically more pronounced, often as a tapped or trilled sound.
