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

Yes

The word "popular" is identical in terms of spelling, grammar, and fundamental meaning (referring to something widely liked, famous, or belonging to the people). The only difference is pronunciation:

• Brazilian Portuguese: The vowels tend to be more open, and the rhythm is more "syllable-timed," which gives the word a more melodic and elongated sound.
• Continental Portuguese: The vowels are often more closed or reduced, and the rhythm is more "stress-timed," which can make the word sound more clipped or "shushed."

Brazilian Portuguese Examples:

1. "Esse cantor é super popular no Brasil." (This singer is super popular in Brazil.)
2. "Ela é uma menina muito popular na escola." (She is a very popular girl at school.)
3. "A música popular brasileira é incrível." (Brazilian popular music is incredible.)
4. "Esse restaurante é bem popular por aqui." (This restaurant is very popular around here.)
5. "O filme foi muito popular entre as crianças." (The movie was very popular among children.)

European Portuguese Examples:

2. "Ela é uma rapariga muito popular na escola." (She is a very popular girl at school.)
