Questions & Answers about Eu tenho o mesmo livro.
I am learning about comparisons like mais do que (more than). How does mesmo fit into comparing things?
Why do we say o mesmo instead of just mesmo?
Just like in English where you say 'the same', Portuguese requires the definite article before mesmo. Because livro (book) is a masculine singular noun, you use the masculine singular article o.
Does mesmo change if the object I own is feminine?
Yes! Because it describes the noun, it has to match the noun's gender and number. If you had the same house (casa, which is feminine), you would say a mesma casa.
Does mesmo always go before the noun it describes?
As a quick refresher, what is the infinitive (dictionary form) of tenho?
