Learn Hardcore Portuguese (Portugal): Também preciso pesquisar sobre o salário médio para não aceitar uma proposta injusta. - I also need to research about the average salary so I don't accept an unfair offer.

It means “also.” In this context, it indicates that in addition to other tasks or considerations (possibly mentioned earlier), the speaker needs to research the average salary.

Why isn’t the subject “I” explicitly mentioned in this sentence?

In Portuguese, the subject is often omitted because the verb conjugation already implies it. The form preciso clearly indicates “I need,” so it’s unnecessary to add eu explicitly.

Why do we use the preposition sobre after pesquisar? Could we say just pesquisar o salário médio instead?

While pesquisar can sometimes take a direct object, in European Portuguese it’s common to use sobre to introduce the topic you’re researching. Saying pesquisar sobre o salário médio clearly specifies that the research is about the average salary.

What does salário médio mean, and why is it accompanied by the article o?

Salário médio translates to “average salary.” The definite article o is used because salário is a masculine noun and the article helps to specify that a particular average salary (the one relevant to the context) is being discussed.

How does the phrase para não aceitar uma proposta injusta function grammatically in the sentence?

This phrase is a purpose clause. The preposition para introduces the infinitive não aceitar, indicating that the research is being done with the intention or purpose of not accepting an unfair proposal. It’s similar to saying “in order not to accept an unfair proposal.”

Why is pesquisar in its infinitive form after preciso?

In Portuguese, when a modal-like adjective such as preciso (meaning “need”) is followed by another verb, that verb is placed in the infinitive. This construction—preciso pesquisar—is used to indicate what action is required.
