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

Yes

The word "tímidos" has the same meaning, spelling, and grammatical function in both Brazilian and Continental Portuguese. The only difference lies in pronunciation:

• Vowel Reduction: In Continental Portuguese, unstressed vowels are often more "closed" or even swallowed (reduced), making the word sound much shorter and more clipped. In Brazilian Portuguese, vowels are more "open" and clearly articulated.
• Sibilance (The "sh" sound): In many regions of Portugal (especially Lisbon), the "s" at the end of the word is pronounced as a "sh" sound (e.g., tímidush). In most of Brazil, the "s" is pronounced as a sharp "s" sound (e.g., tímidos).
