af hverju / hvers vegna

Why (Af Hverju)

Level 1

af hverju and hvers vegna both mean why: Af hverju ertu þreytt? (Why are you tired?)

How It Works

Two ways to say why

  • af hverju, literally from what, is the most common, in speech and in writing.
  • hvers vegna, literally for the sake of what, is also everyday Icelandic and appears a lot in writing.

Use either one. A third word, hví, is old-fashioned and rare today.

Word order
The question phrase counts as one unit in first place, so the verb comes next: Af hverju kemurðu ekki? (Why aren't you coming?) See The Verb Comes Second. A very short question needs no verb: Af hverju ekki? (Why not?)

Answering
Start with Because (af því að) and keep normal statement order: Af því að ég er veik. (Because I'm sick.) A more formal answer uses Because (vegna þess að).

Spelling
af hverju is always two words. The joined spelling afhverju is common online but is not correct.

Common Mistakes

  • Keeping statement order after af hverju.

    Af hverju þú ert að læra íslensku?
    Af hverju ertu að læra íslensku?

    af hverju counts as the first part of the sentence, so the verb must come next, before the subject.

  • Writing af hverju as one word.

    Afhverju ertu svona þreytt?
    Af hverju ertu svona þreytt?

    The official Icelandic spelling rules write af hverju as two words.
