Questions & Answers about O código postal está no computador.
Why do we use está here instead of é?
Está comes from the verb estar, which is used for locations. In Portuguese, we almost always use estar to talk about where something is located, whether it is a physical object or digital information. Ser (which gives us é) is used for permanent characteristics, like what a thing is or where someone is originally from.
The English translation says "on the computer", but doesn't no mean "in the"?
The word no is a contraction of the preposition em (in/on/at) and the masculine word for "the", o. In Portuguese, em and its contractions cover "in", "on", and "at" in English. So no computador translates to "in the computer" or "on the computer" depending on what sounds best in English.
Why is it código postal instead of postal código?
In Portuguese, adjectives (descriptive words like postal) almost always come after the noun they describe (like código). So instead of saying "postal code", the sentence literally says "code postal".
