The Subordinate Clause Rule: Adverbs Before Verbs
In Danish, central adverbs—words like altid (always), aldrig (never), ofte (often), and også (also)—usually come after the verb in a normal main clause.
However, in subordinate clauses (dependent clauses starting with words like at, fordi, or hvis), there is a strict word order rule: the central adverb must come before the finite verb.
Notice how the adverbs altid and aldrig step right in front of the verbs kommer and sover in these at (that) clauses:
| I expect that he always comes. | Jeg forventer at han altid kommer. |
| It is typical that the child never sleeps at night. | Det er typisk at barnet aldrig sover om natten. |
Cause and Condition: Fordi and Hvis
The same rule applies when giving reasons with fordi (because) or setting conditions with hvis (if).
Here is a new adverb to practice with:
| rarely | sjældent |
| I am angry because my sister rarely listens. | Jeg er sur fordi min søster sjældent lytter. |
| If they rarely work, we cannot help them. | Hvis de sjældent arbejder, kan vi ikke hjælpe dem. |
Notice in the example above how sjældent comes right before the verb arbejder. Also recall the V2 rule: because the sentence starts with a subordinate hvis-clause, the main clause that follows must invert its subject and verb (kan vi instead of vi kan).
Let's look at one more example using ofte:
| The behavior is a problem because she often laughs. | Opførslen er et problem fordi hun ofte griner. |
Expressing Opinions and Reactions
Placing the adverb before the verb in subordinate clauses is an essential habit to build, as you will use this structure constantly when reacting to situations, stating requirements, or commenting on behavior.
| It surprises me that you always arrive late. | Det overrasker mig at du altid ankommer sent. |
| The customer is dissatisfied because the food is always cold. | Kunden er utilfreds fordi maden altid er kold. |
