Перевод - Португальский (Бразилия)-Английский - Eu não sei falar em ingles. So algumas palavras...

English.

Sorry...
It's capital only with the word English? If I say portuguese, should it have capital P too?
If not: I really hate this capital E.

English has its own freaks. All proper names, nationalities, months of the year, days of the week, the pronoun "I" and so on,... take capital letters. So, Portuguese is not an exception.

Oh, ok, hehehe.

Achei que era algo de superioridade do tipo: Americano, sendo que eu os chamo de Estadounidenses. Nada a ver, mas tudo bem.
