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

Yes

The word "receber" is identical in meaning, spelling, and grammar in both Brazilian and Continental Portuguese. The differences are strictly phonetic:

• Vowel Openness: Brazilian Portuguese tends to pronounce vowels more openly and clearly. In Continental Portuguese, unstressed vowels are much more "reduced" or swallowed, which can make the word sound shorter and more closed.
• The Final "R": In many Brazilian dialects, the final "r" in "receber" is more distinct or slightly aspirated (like an "h" sound). In Portugal, the final "r" is often very subtle or nearly silent in natural, fast-paced speech.

Brazilian Portuguese Examples:

1. Eu recebi um presente de aniversário. (I received a birthday present.)
2. Ela recebeu o salário ontem. (She received her salary yesterday.)
3. Nós recebemos muitas mensagens no WhatsApp. (We received many messages on WhatsApp.)
4. Você recebeu o meu e-mail? (Did you receive my email?)
5. Ele gosta de receber visitas no fim de semana. (He likes to receive visitors on the weekend.)
