Why does this sentence begin with the article "O"? I'm having trouble comprehending this.
when the possessive works as adjective, you can choose whether or not use the definite article. Here it is opitional.
What is the difference between minha and meu?
Minha is used for feminine nouns and meu for masculine. If you own a dog (o cachorro) you say: "O meu cachorro". If you own a skirt (a saia) you would say: "A minha saia".
Yeah, I often have trouble with this, too. Can somebody explain this?
They refer to the gender of the object. If the object is feminine, you use "minha" if it is masculine, you use " meu" instead.
Example: Minha mãe but meu pai.
