Introduction

<em>Chamo-me Claire Ann.</em>

This is the formal written form.

You can also say "Meu nome é Claire Ann". Literally, "My name is".

But the informal spoken and written form would be "Me chamo Claire Ann".

<em>Eu sou estudante de Psicologia e História de Arte na universidade de Toronto, no Canadá.</em>

"Em Canadá" is not incorrect, but it's almost nonexistent in the Brazilian Portuguese.

"Na" and "no" in this context is simply "in the" or "in", varying according to the gender of the nouns.

<em>Eu tenho vinte e sete anos. </em>
