This is the 3011th most frequent Portuguese word.
vai
"Vai" means "goes" or "is going" in English.
In this sentence, 'vai' is the third-person singular present indicative form of the verb 'ir' ('to go'), denoting an action in the present moment.
Ele vai ao mercado agora.
He is going to the market now.
In this sentence, 'vai' acts as part of a future verbal construction, coupled with the infinitive 'chover' ('to rain'), indicating that the action will take place in the future.
Vai chover mais tarde.
It will rain later.
Here, 'vai' introduces a future consequence or outcome, again forming a future tense when used before the infinitive verb 'perder' ('to lose').
