Questions & Answers about A missão terminou à noite.
Because missão is a feminine singular noun, and Portuguese often uses the definite article where English might not.
- a = the for feminine singular nouns
- missão = mission
So A missão literally means The mission.
In Portuguese, it is very natural to say A missão terminou, whereas in English you might sometimes prefer just Mission accomplished or The mission ended, depending on context.
Nouns in Portuguese have grammatical gender, and missão is a feminine noun.
That is why it takes:
- a in the singular: a missão
- as in the plural: as missões
This grammatical gender does not necessarily have anything to do with biological sex. It is simply a property of the noun that affects articles, adjectives, and some other words.
