Questions & Answers about Vi har inte mycket tid innan snön kommer.
Why do we use mycket here instead of många?
In this sentence, time (tid) is treated as an uncountable amount, just like water or air. Because you cannot count individual units of time here, we use mycket (much). If you were talking about countable things, like many days, you would use många.
Why does inte come right after har?
In standard Swedish main clauses, the word inte (not) usually goes directly after the verb. So instead of using a helper phrase like the English do not have, Swedish simply says have not (har inte).
Why is there an n at the end of snön?
That -n at the end is how Swedish makes the noun definite. The base word is snö (snow), and because it is an en-word, adding -n changes it to the snow (snön).
Does kommer just mean comes, or can it refer to the future here?
It refers to the future! Swedish often uses the present tense (kommer) to talk about future events, especially when a word like innan (before) already makes it clear that the action hasn't happened yet.
