Icelandic builds questions in just two ways, and both are simpler than the English machinery you are used to. A yes/no question is made by inversion: you move the finite verb to the front, ahead of the subject (Talar þú íslensku? "Do you speak Icelandic?"). A wh-question fronts a question word (hvað, hver, hvar …) and then keeps the verb in second position. The single most important thing to unlearn is the English helper "do" — Icelandic has no "do"-support at all. There is no verb you insert to ask a question; you simply rearrange the words you already have.
Yes/no questions: invert the verb and subject
To turn a statement into a yes/no question, take the finite verb (the one carrying tense and person) and put it first, with the subject right after it. That is the whole rule. A statement is Þú talar íslensku ("You speak Icelandic"); the question is Talar þú íslensku? The verb and subject simply swap places.
Talar þú íslensku?
Do you speak Icelandic? (statement Þú talar íslensku → verb first)
Ert þú þreyttur?
Are you tired? (said to a man — þreyttur is masculine)
Kemur hún í kvöld?
Is she coming tonight?
Notice there is no extra word anywhere. English needs a helper — "Do you speak," "Are you," "Is she" — but for "speak" Icelandic just lifts talar to the front. The verb that was already in the sentence does all the work.
No "do"-support — the hardest habit to break
English speakers reflexively want a "do." To make "You like coffee" into a question, English inserts do: "Do you like coffee?" Icelandic finds this baffling — gera ("to do") is a real verb meaning "to do/make," and inserting it produces nonsense. The Icelandic question is built only by moving the verb you already have.
Drekkur þú kaffi?
Do you drink coffee? (NOT *Gerir þú drekka kaffi)
Skilur þú þetta?
Do you understand this?
The verb drekkur / skilur moves to the front by itself. There is nothing to add. Once you internalise that "do" simply does not exist as a question-builder, half of Icelandic question formation is already behind you.
Wh-questions: front the question word, keep the verb second
For an information question, you put a question word at the very front, and the finite verb comes immediately after it, in second position. This is the famous Icelandic V2 ("verb-second") rule: whatever opens the clause, the finite verb is the second element. The question word fills the first slot, the verb the second, and the subject follows.
The core A1 question words:
| Word | Meaning | Note |
|---|---|---|
| hvað | what | the workhorse question word |
| hver | who / which | declines for case (see its page) |
| hvar | where (at) | static location |
| hvert | where to (whither) | motion toward |
| hvaðan | where from (whence) | motion away / origin |
| hvenær | when | |
| hvernig | how | |
| af hverju / hvers vegna | why | af hverju is the everyday form |
A useful detail English collapses: Icelandic keeps three "where" words apart by direction. Hvar asks about a static place ("where are you?"), hvert about motion toward ("where are you going?"), and hvaðan about origin ("where are you from?"). English uses "where" for all three (with "from"/"to" patched on), so this three-way split is something to watch.
Hvar býrð þú?
Where do you live? (static location → hvar)
Hvert ertu að fara?
Where are you going? (motion toward → hvert; ertu = ert þú)
Hvaðan ertu?
Where are you from? (origin → hvaðan)
Hvenær kemur lestin?
When does the train arrive?
Hvað segir þú?
What do you say? / What's up? (a common greeting)
In every one of these the verb (býrð, ert, kemur, segir) sits in second position, right after the question word, exactly as V2 demands. There is no "do" here either.
The spoken clitic forms: ertu, áttu, viltu
Here is the high-frequency reality that textbooks often skip. In speech, the subject pronoun þú ("you") fuses onto the end of the verb. The unstressed þú leans on the verb and reduces to -(t)u, so the everyday spoken question form looks different from the careful written one:
| Written-formal | Spoken (clitic) | Meaning |
|---|---|---|
| ert þú | ertu | are you |
| átt þú | áttu | do you have / own |
| vilt þú | viltu | do you want |
| kemur þú | kemurðu | are you coming |
| kannt þú | kanntu | can you / do you know how |
This fusion is not slang — it is the normal, neutral way Icelanders ask a þú-question out loud. The fuller ert þú is (formal) or emphatic; ertu is the unmarked everyday form (informal). Learn both: you will read ert þú and hear ertu.
Áttu bíl?
Do you have a car? (áttu = átt þú; literally 'own you')
Viltu kaffi?
Do you want coffee? (viltu = vilt þú)
Kemurðu með okkur?
Are you coming with us? (kemurðu = kemur þú)
Intonation: rising vs falling
Word order does the grammatical work, but intonation still matters. A yes/no question typically ends on a rising pitch — the voice lifts at the end, much as in English. A wh-question, by contrast, usually falls at the end, because the question word already signals that it is a question; the pitch does not need to rise. So Talar þú íslensku? rises, while Hvar býrð þú? falls. Unlike English, though, you cannot rely on intonation alone: you must still invert (for yes/no) or front a wh-word.
Common Mistakes
❌ Gerir þú tala íslensku?
Incorrect — Icelandic has no 'do'-support; just invert the real verb.
✅ Talar þú íslensku?
Do you speak Icelandic?
There is no helper "do." Move the actual verb (talar) to the front; gera means "to do/make" and makes no sense here.
❌ Þú talar íslensku?
Incorrect as a real question — statement order needs verb-first inversion.
✅ Talar þú íslensku?
Do you speak Icelandic?
A rising tone on statement order is not enough; you must actually invert the verb and subject.
❌ Hvar þú býrð?
Incorrect — after the question word the verb must come second (V2).
✅ Hvar býrð þú?
Where do you live?
In a wh-question the finite verb sits immediately after the question word, not after the subject.
❌ Hvaðan ertu að fara?
Mismatched direction — 'where to' for going is hvert, not hvaðan.
✅ Hvert ertu að fara?
Where are you going?
Hvaðan is "from where" (origin); for motion toward a destination use hvert.
Key Takeaways
- Yes/no questions = inversion: finite verb first, subject second (Talar þú …? Ert þú …?).
- Wh-questions = question word first, then the verb in second position (V2): Hvar býrð þú?
- Icelandic has no "do"-support — never insert gera; just move the real verb.
- Keep the three "where" words apart: hvar (at), hvert (to), hvaðan (from).
- In speech, þú fuses onto the verb: ertu, áttu, viltu, kemurðu, kanntu — learn these from day one.
- Yes/no questions tend to rise in pitch; wh-questions tend to fall — but intonation never replaces inversion.
