Questions & Answers about O capitão prefere que tu apertes o cinto na cabine.
Why do we use apertes instead of apertas in this sentence?
The phrase prefere que (prefers that) expresses a preference. In Portuguese, when one person (the captain) prefers that someone else (you) does something, the second verb must be in the present subjunctive. That is why the normal present tense apertas changes to the subjunctive apertes.
How do we get the ending for apertes?
The verb is apertar (to fasten or tighten). To form the present subjunctive, regular -ar verbs swap their usual a vowel for an e. Because the subject is tu (you), we add the expected -s ending, making it apertes.
Is it necessary to include the pronoun tu after que?
