Learn Swedish: Ska du se filmen imorgon? - Are you going to see the film tomorrow?

Because this is a yes/no question. Just like in English, Swedish questions swap the order of the subject (du) and the verb. Since ska is the helper verb showing future intention, it takes the first spot.

Why is the verb se used without att (to) here?

The word ska ("going to" or "will") is a helper verb. In Swedish, helper verbs are followed directly by the base form of the next verb, without att. It is just like English where you say "will see" rather than "will to see".

Can I use titta instead of se since we are talking about watching a movie?

You can say titta på filmen ("watch the film"), but using se is very common and natural in Swedish. It works exactly like saying "see a film" in English.

How does filmen translate to "the film"?

In Swedish, "the" is not a separate word before the noun. Instead, it is added as an ending. The base word is film (a film), and adding -en to the end turns it into filmen (the film).

Are imorgon and i morgon the same thing?
