Learn Hardcore Portuguese (Brazil): Respeitar as regras ajuda a manter a ordem na casa. - Respecting the rules helps keep order in the house.

The literal translation is "Respecting the rules helps maintain order in the house." In this translation, "respeitar" means "to respect" (or "respecting" when used as a gerund), "as regras" is "the rules," "ajuda" means "helps," "a manter" translates to "to maintain," and "a ordem na casa" means "order in the house." This translation closely follows the structure of the Portuguese sentence.

Why does the sentence use an infinitive phrase ("Respeitar as regras") as the subject instead of a conjugated noun phrase?

In Portuguese, it's common to use the infinitive as a subject to express general ideas or actions. The phrase "Respeitar as regras" serves as a nominal expression, equivalent to the English "Respecting the rules" or "To respect the rules." This construction conveys a general truth without specifying a particular agent.

What is the purpose of the preposition "a" in the phrase "ajuda a manter"?

The preposition "a" in "ajuda a manter" is used to link the main verb "ajuda" (meaning "helps") with the following infinitive "manter" (meaning "to maintain"). In Portuguese, many verbs that express assistance or facilitation require the preposition "a" before the infinitive that details the action being helped to occur, much like in English we sometimes say "helps to maintain."

What does the contraction "na" in "na casa" represent, and why is it used here?

The term "na" is a contraction of "em" (meaning "in") and "a" (the feminine definite article meaning "the"). Thus, "na casa" translates to "in the house." This contraction is standard in Portuguese when the preposition "em" is immediately followed by the feminine article "a".

Why is the infinitive "manter" not conjugated, and what does it imply in this context?

The infinitive "manter" remains in its unconjugated form because it is linked to the verb "ajuda" by the preposition "a." In this construction, "ajuda" is the conjugated verb (in the third person singular), and it governs the infinitive "manter." This pattern is typical in Portuguese when a main verb is followed by an action expressed in the infinitive—similar to the structure in English where we might say "helps maintain" or "helps to maintain."
