When do you put an O or A before the words Meu Minha in Brazilian Portuguese?

You use "O" or "A" before "Meu" and "Minha" in Brazilian Portuguese to agree with the gender of the noun that follows them.

Here's the breakdown:

* "O Meu" is used before masculine nouns:

* O meu carro (My car)

* O meu livro (My book)

* "A Minha" is used before feminine nouns:

* A minha casa (My house)

* A minha irmã (My sister)

Examples:

* O meu amigo (My friend) - "Amigo" is masculine.

* A minha irmã (My sister) - "Irmã" is feminine.

* O meu cachorro (My dog) - "Cachorro" is masculine.

* A minha gata (My cat) - "Gata" is feminine.

Important Notes:

* If the noun is plural, you'll use "Os meus" (masculine) or "As minhas" (feminine).

* Os meus livros (My books)

* As minhas irmãs (My sisters)

* Sometimes "Meu" and "Minha" can be used directly before the noun without "O" or "A" for emphasis.

* Meu carro novo (My new car) - Emphasis on the car being yours.

* Minha casa linda (My beautiful house) - Emphasis on the house being yours.
