Questions & Answers about Tu exportarias o produto para Londres?
How is the conditional verb exportarias formed in this sentence?
For regular verbs in the conditional tense, you take the full infinitive verb (here, exportar) and add the conditional endings. Since the subject is tu (you, informal), the ending is -ias. Put them together, and you get exportarias (would export).
Why do we use para instead of a for to London?
In Portuguese, para is used for a final destination or a longer-term move. Because exporting a product implies sending it to its final destination, para is the natural choice here. If you used a, it would imply a quick round-trip visit, which does not make sense for sending cargo.
How would this sentence change if I were speaking to someone formally?
You would drop the informal tu and use the formal you. The verb ending changes to match the third-person singular, which for regular conditional verbs is -ia. So the sentence becomes: Você exportaria o produto para Londres? or simply Exportaria o produto para Londres?
Why is there no definite article like a before Londres?
Most cities in Portuguese do not take a definite article like o or a. You just use the preposition directly attached to the city name. Therefore, it is simply para Londres rather than para a Londres.
