"She does not speak English."
Translation:Hon talar inte engelska.
The main rule is the V2 rule: In any sentence (except questions and subclauses) the finite verb needs to be in second place. The finite verb is the one that can show time (like, I sing - I sang, sing/sang are finite verbs. In 'I love to read', love is a finite verb, but not read).
With very few exceptions, yes. :) One exception to be something like "I can't make her if she doesn't want to" - "Jag kan inte tvinga henne om hon inte vill" OR "If you don't do this, you're fired" - "Om du inte gör det här blir du avskedad".
But in simple sentences like this in the beginning of the course, it's safe to assume that "inte" comes after the verb. You'll probably learn the exceptions further down the road.
