Main clause inversion

The V2 Rule: Fronting a Subordinate Clause

Danish is a "V2" (verb-second) language, meaning the verb is always the second element in a main clause.

When you start a sentence with a subordinate clause—such as those beginning with hvis (if), når (when), or selvom (even though)—that entire clause counts as the first element. To keep the main verb in the second position, the main clause must start immediately with its verb, inverting the usual subject-verb order.

Notice how the main verbs (kan, forsvinder) come right after the comma:

When the boy eats the garlic, the evil witch cannot find him.
Når drengen spiser hvidløget, kan den onde heks ikke finde ham.
If the girl carries the cross, the evil ghost disappears.
Hvis pigen bærer korset, forsvinder det onde spøgelse.

Word Order with Adverbs

If your inverted main clause includes an adverb like altid (always) or ikke (not), the adverb comes after both the verb and the subject.

Structure: [Subordinate Clause], [Verb] + [Subject] + [Adverb]
