Questions & Answers about Dá lá o assobio antes que a batida comece.
What exactly is the word lá doing in this sentence?
Why do we use comece instead of the normal present tense começa?
The phrase antes que always triggers the subjunctive mood because it introduces an anticipated action that has not happened yet. Because of this rule, the verb começar is forced into its present subjunctive form, comece.
Could I just use the verb for whistling and say assobia lá?
Yes, you absolutely can. Saying dá o assobio is a slightly more colloquial choice that frames the whistle as a specific, expected signal (like a starting cue) rather than just the general action of whistling.
How would this sentence change if I were speaking formally to a você?
Dá is the informal tu imperative form of the verb dar. If you were speaking formally, you would use the formal imperative dê, making the first part of the sentence Dê lá o assobio.
