Questions & Answers about Queremos assegurar que não fizemos nada de errado.
Can we drop the que in this sentence to make it more formal, like in other examples from this lesson?
No. The omission of que is typically reserved for highly formal contexts involving verbs of requesting, hoping, or commanding that trigger the subjunctive (such as espero compreendam instead of espero que compreendam). Because assegurar is a verb of declaring that triggers the indicative (fizemos), the que cannot be dropped.
The English translation says 'assure you', but there is no word for 'you' in the Portuguese sentence. Is it missing?
It is not missing, just implied. In Portuguese, it is perfectly natural to leave out the indirect object pronoun (like vos, lhe, or lhes) when the context makes it obvious who is being addressed. If you wanted to be completely explicit, you could add it to the verb, for example: Queremos assegurar-lhe (assure you, formal singular) or Queremos assegurar-vos (assure you, plural).
Why is there a de in nada de errado?
In Portuguese, whenever you modify an indefinite pronoun like nada (nothing), algo (something), or tudo (everything) with an adjective, you must link them using the preposition de. Therefore, the English phrase 'nothing wrong' must be structured as 'nothing of wrong' (nada de errado).
Since this is a subordinate clause following que, why do we use the indicative fizemos instead of the subjunctive?
