Questions & Answers about Quero reservar um quarto no hotel.
Why isn't there a word for "to" between Quero and reservar?
The translation says "I want", but where is the word for "I"?
In Portuguese, you don't usually need to say the subject pronoun (eu for "I") because the verb ending already tells you who is doing the action. Quero can only mean "I want", so adding eu is optional and usually dropped to sound more natural.
Why is it no hotel instead of "em o hotel"?
I thought quarto meant "fourth". Why does it mean "room" here?
Quarto is a word with multiple meanings. While it does mean "fourth" or "a quarter", it is also the standard Portuguese word for a bedroom or a hotel room. The context of the sentence makes it clear which meaning is intended here.
