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

Yes

The word "tarde" is identical in Brazilian and Continental Portuguese regarding its meaning (afternoon/late), spelling, and grammar. The only difference lies in pronunciation:

• Brazilian Portuguese: The vowels are generally more open and melodic. The final "e" is often pronounced more clearly or as a light "i" sound (e.g., tar-dji).
• Continental Portuguese: The pronunciation is more "closed" and stress-timed. The final "e" is often extremely reduced, sounding like a faint whisper or nearly disappearing (e.g., tard).

3. A tarde está muito quente hoje. (The afternoon is very hot today.)
4. Não chegue tarde para o jantar. (Don't arrive late for dinner.)
