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

Yes

The word "design" is an English loanword used in both Brazilian and Continental Portuguese with identical meaning, spelling, and grammatical function (as a masculine noun). The only difference is in pronunciation:

• Brazilian Portuguese: The pronunciation is typically "Lusophonized," often sounding like de-ZINE (with a soft "d" and a vowel sound closer to "ee").
• Continental Portuguese: The pronunciation often stays closer to the original English phonetic structure, sounding more like di-ZAIN.
