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

Yes

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

• Brazilian Portuguese: The pronunciation is more open and "musical." The vowels are clearly articulated, and the rhythm is syllable-timed (each syllable receives relatively equal emphasis).
• Continental Portuguese: The pronunciation is more "closed" and dense. Unstressed vowels are often reduced or almost swallowed, and the rhythm is stress-timed (emphasis is placed heavily on certain syllables, while others are shortened).

Brazilian Portuguese Examples:

1. Eu estou aprendendo italiano. (I am learning Italian.)
2. Você gosta de comida italiana? (Do you like Italian food?)
3. Ele é um chef italiano muito famoso. (He is a very famous Italian chef.)
4. Eu adoro massa italiana. (I love Italian pasta.)
5. O meu amigo é italiano. (My friend is Italian.)
