Questions & Answers about He eivät tule sisään.
How do we get the negative form tule from the dictionary word tulla?
tulla (to come) is a Type 3 verb. To make its stem, you drop the last two letters (-la) and add an -e, which gives you tule-. In negative sentences, the main verb is simply this stem without any extra personal endings.
Why do we use eivät instead of ei?
In Finnish, the negative word acts like a verb and changes depending on who you are talking about. Because the subject is he (they), the negative verb must be the matching plural form eivät. The main verb (tule) remains in its stem form.
What does sisään mean, and why don't we use sisällä?
sisään means in or inside when there is movement involved. Since the action is coming into a place, you use sisään. If someone was already inside and staying there, you would use the location word sisällä.
Do I need to include the pronoun he in this sentence?
Yes. In standard Finnish, you can often drop the pronouns for I and you, but you must always keep the pronouns for he/she (hän) and they (he).
