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

Yes

The word "favorita" is identical in spelling, meaning, and grammatical function in both Brazilian and Continental Portuguese. The only difference is in pronunciation:

• Brazilian Portuguese: The vowels are generally more open and clearly articulated. The "t" in "favorita" is typically pronounced as a dental [t], though in certain regions (such as Rio de Janeiro or São Paulo), it may be palatalized to [tʃ], sounding like the "ch" in "cheese."
• Continental Portuguese: The vowels are much more closed and often reduced (almost swallowed). The "t" before an "i" sound is almost always palatalized as [tʃ], creating a distinct "ch" sound.

Brazilian Portuguese Examples:

1. Essa é a minha cor favorita. (That is my favorite color.)
2. A pizza de calabresa é a minha favorita. (Pepperoni pizza is my favorite.)
3. Qual é a sua comida favorita? (What is your favorite food?)
4. Ela é a minha atriz favorita. (She is my favorite actress.)
5. Essa é a minha série favorita. (That is my favorite series.)

Continental Portuguese Examples:

1. Esta é a minha cor favorita. (This is my favorite color.)
2. A pizza de chouriço é a minha favorita. (Sausage pizza is my favorite.)
3. Qual é a tua comida favorita? (What is your favorite food?)
4. Ela é a minha atriz favorita. (She is my favorite actress.)
5. Esta é a minha série favorita de sempre. (This is my all-time favorite series.)
