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

Yes

The meaning, spelling, and grammar of "divertido" are identical in both Brazilian and Continental Portuguese. The only difference is pronunciation. In Brazilian Portuguese, the vowels are more open and the rhythm is "syllable-timed," meaning each syllable is articulated clearly. In Continental Portuguese, the rhythm is "stress-timed" and vowels are often "reduced" or "closed." This means unstressed vowels (such as the "i" in "divertido") are often swallowed or pronounced very lightly, making the word sound more clipped or muffled to a Brazilian ear.

Brazilian Portuguese Examples:

1. O filme foi super divertido! (The movie was super fun!)
2. Ele é um cara muito divertido. (He is a very fun guy.)
3. A festa ontem estava bem divertida. (The party yesterday was quite fun.)
4. Que passeio divertido a gente teve! (What a fun outing we had!)
5. Achei esse jogo muito divertido. (I found this game very fun.)

Continental Portuguese Examples:

1. O filme foi bastante divertido. (The movie was quite fun.)
2. Ele é uma pessoa muito divertida. (He is a very fun person.)
3. A festa de ontem foi muito divertida. (Yesterday's party was very fun.)
4. Que passeio tão divertido tivemos! (What a very fun outing we had!)
