✦Grammar Breakdown
Nasextanãovouestar
Na (em + a)
The preposition *em* (in/on) contracts with the feminine article *a* to form *na*, meaning “on” or “in” before a feminine noun.
Dia da semana (sexta)
*Sexta* is the feminine noun for Friday; days of the week are treated as nouns and take the article when used with a preposition.
Negação (não)
*Não* precedes the verb (or verb phrase) to negate it. It always comes before the conjugated verb.
Futuro próximo (vou + infinitivo)
The construction *vou + infinitive* (I will) expresses a near‑future intention, similar to English “I’m going to…”.
Infinitivo (estar)
*Estar* is the infinitive of the verb “to be” (temporary state or location). In the near‑future construction it stays in the infinitive.

All right, we’ll see each other on Monday then.
✕Common Mistakes
Na sexta eu vou não estar.
Learners often forget that *não* must come before the conjugated verb *vou*; placing it after *vou* (*vou não estar*) is incorrect.
Na sexta não vou estar.
In formal contexts, native speakers usually prefer *estarei* instead of the near‑future *vou estar*.
Na Sexta não vou estar.
The day name should stay lowercase unless it begins the sentence; writing *Sexta* is a common mistake for learners.

I won’t be (there) on Friday.

Cultural Tip
In Brazil, the near‑future *vou + infinitive* is very common in spoken language, especially for informal plans. However, many speakers prefer the simple future *estarei* for a slightly more formal tone. Also, note that days of the week are not capitalized in Portuguese unless they start a sentence.
