Learn German: Vor allem am Wochenende arbeite ich nicht. - Above all at the weekend I do not work.

In German, the conjugated verb must always be in the second position of a statement. Since the time phrase Vor allem am Wochenende takes up the entire first position, the verb arbeite comes second. This pushes the subject ich into the third position. This is exactly the same V2 rule you use when starting a sentence with adverbial connectors like deshalb or darum!

What does the phrase vor allem mean?

Vor allem literally translates to "before all," but it is a common fixed expression that means "above all," "especially," or "primarily."

Why do we say am Wochenende instead of just an Wochenende?

Time expressions answering the question "when?" usually require the dative case. The word Wochenende is neuter (das Wochenende), so its dative article is dem. The preposition an merges with dem to create the short word am.

Why does nicht go at the very end of this sentence?

When you negate the entire action of a sentence (in this case, the fact that you work), the word nicht typically moves to the very end of the clause.
