Change Of State Intransitives

Level 5

In Danish, many verbs can function both transitively (I open the door) and intransitively (The door opens). This 'anti-causative' use focuses on the process itself rather than who did it.

How It Works

Danish anti-causatives generally fall into three categories:

1. Labile Verbs (Zero-marked): These are the most common. The verb form does not change between the transitive and intransitive use. Examples include åbne (open), lukke (close), koge (boil), and smelte (melt).

  • Jeg koger vandet (Transitive: I am the agent)
  • Vandet koger (Anti-causative: The water is boiling)

2. Reflexive Anti-causatives: Some verbs require the reflexive pronoun sig to indicate the change of state. This often implies a physical or spontaneous movement.

  • Døren åbnede sig (The door opened [by itself/physically])
  • Verden forandrer sig (The world is changing)

3. Ablaut Pairs (Historical): A few high-frequency verbs use a vowel change to distinguish the action (causative) from the state (intransitive).

  • lægge (to lay something) vs. ligge (to lie/be lying)
  • Sætte (to set) vs. sidde (to sit)

Nuance: Use the anti-causative (Butikken åbner) for scheduled or functional events. Use the s-passive (Døren åbnes) when you want to imply that an agent is currently performing the action.

Examples (5)

  1. Butikken åbner klokken ni.

    The shop opens at nine.

    Word by Word: The shop opens at clock nine.

    A labile use of 'åbne'. It describes a scheduled event rather than a physical movement caused by a person at that moment.

  2. Isen smelter i solen.

    The ice is melting in the sun.

    Word by Word: The ice melts in the sun.

    A natural change of state where the ice is the subject. No external agent is 'melting' it; it happens spontaneously.

  3. Pludselig åbnede døren sig.

    Suddenly the door opened.

    Word by Word: Suddenly opened the door itself.

    The reflexive 'sig' is used here to emphasize the physical, spontaneous movement of the door opening 'on its own'.

  4. Vandet er kogt nu.

    The water has boiled now.

    Word by Word: The water is boiled now.

    In the perfect tense, anti-causative verbs (change of state) use 'er' instead of 'har'. See 'er + participium'.

  5. Han lagde bogen på bordet, og nu ligger den der.

    He laid the book on the table, and now it is lying there.

    Word by Word: He laid the book on the table, and now lies it there.

    This shows the ablaut pair: 'lægge' (transitive action) vs 'ligge' (intransitive state).

Common Mistakes

  • Using the passive voice for natural processes.

    Different MeaningIsen bliver smeltet af solen.
    Isen smelter i solen.

    While grammatically possible, 'bliver smeltet' sounds like a deliberate action. For natural changes, Danish prefers the simple anti-causative verb.

  • Adding 'sig' to verbs that don't need it.

    Vandet koger sig.
    Vandet koger.

    Verbs like 'koge' (boil) and 'smelte' (melt) are labile and do not take a reflexive pronoun in Danish.

  • Confusing 'lægge' and 'ligge'.

    Jeg ligger bogen på bordet.
    Jeg lægger bogen på bordet.

    'Ligge' is intransitive (the book lies). 'Lægge' is transitive (I lay the book). You cannot 'ligge' an object.
