Questions & Answers about A pressão máxima aparece no pneu.

Why is there a before pressão máxima?

Because Portuguese normally uses the definite article with a subject like this.

So A pressão máxima means the maximum pressure. In English, we sometimes drop the in general statements, but in Portuguese a full sentence like this usually sounds more natural with the article.

• A pressão máxima aparece no pneu. = The maximum pressure appears on the tire.

Leaving out a here would sound unnatural in normal speech.

Why is it máxima and not máximo?

Because adjectives in Portuguese must agree with the noun they describe in gender and number.

• pressão is feminine singular
• so the adjective must also be feminine singular
• therefore: máxima

Compare:

• pressão máxima = maximum pressure
• valor máximo = maximum value

Since valor is masculine, the adjective becomes máximo.

Why does máxima come after pressão?
