To negate a sentence in Icelandic, you reach for one small word: ekki ("not"). It is the core sentential negator, and the single most important fact about it is where it goes. In a main clause, ekki sits after the finite verb — Ég kem ekki ("I'm not coming"), not Ég ekki kem. That placement is not an isolated quirk: ekki occupies a fixed mid-clause slot, so learning where it lands quietly teaches you the whole architecture of the Icelandic sentence. This page orients you to the system; the finer placement rules and the negative pronouns each have their own page.
ekki goes AFTER the finite verb
The basic rule for a simple main clause: put ekki right after the finite verb. English puts "not" after the auxiliary ("I do not come," "I am not coming") and inserts a "do" when there is no other auxiliary. Icelandic has no "do" — ekki simply follows whatever finite verb is already there.
Ég veit ekki.
I don't know. (the single most useful negative sentence — verb veit, then ekki)
Hann er ekki heima.
He's not home. (er, then ekki)
Hún borðar ekki kjöt.
She doesn't eat meat. (borðar, then ekki, then the object kjöt)
In each case the finite verb (veit, er, borðar) comes first, ekki immediately follows it, and the rest of the clause continues. There is nothing to "do"-support and nothing to add — you slot ekki in behind the verb.
The order with objects: pronoun before ekki, full noun after
Here is the detail that makes ekki such a revealing little word. Where exactly it lands depends on what else is in the clause — and pronoun objects behave differently from full-noun objects.
A pronoun object (hann "him," það "it," mig "me") is light and unstressed, so it scoots in before ekki. A full noun phrase object, being heavier and informationally new, stays after ekki.
Ég sé hann ekki.
I don't see him. (pronoun object hann comes BEFORE ekki)
Ég sé ekki manninn.
I don't see the man. (full-noun object manninn comes AFTER ekki)
Look at the contrast directly: hann ekki but ekki manninn. The dividing line is ekki: light, given pronouns shift left of it; heavy, new noun phrases stay right of it. This is not random — it reflects a general principle that unstressed pronouns cliticise into the verbal field, a pattern you will meet again with reflexives and other short elements.
Ég þekki hana ekki.
I don't know her. (pronoun hana before ekki)
Ég þekki ekki konuna.
I don't know the woman. (full noun konuna after ekki)
ekki as a diagnostic of clause structure
Why dwell on one word? Because ekki marks the boundary of the clause's mid-field — the zone between the verb and the rest of the content. Its position is fixed relative to that boundary, so ekki acts as a probe: wherever ekki sits tells you where the structural seams of the sentence are. Learn the slot ekki occupies and you have effectively learned the skeleton of Icelandic word order. This is why a good grammar treats negation placement not as a footnote but as a gateway to syntax.
One consequence to flag now (detailed on its own page): ekki's position shifts in subordinate clauses. In a main clause it follows the finite verb; in a subordinate clause it comes before the finite verb (…að ég kem ekki vs. …að ég ekki kem in certain clause types). That contrast — verb-before-ekki in main clauses, ekki-before-verb in subordinate ones — is one of the clearest windows into the difference between the two clause types.
Beyond ekki: the rest of the negative toolkit
Ekki is sentential "not," but Icelandic has dedicated negative words for "no/none," "never," and "nothing." You will meet these properly on the negative-words page; here is the orientation:
| Word | Meaning | Note |
|---|---|---|
| ekki | not | sentential negator (this page) |
| enginn | no / none / nobody | declines for gender, number, case |
| aldrei | never | adverb, sits where ekki would |
| ekkert | nothing | the neuter of enginn, used as 'nothing' |
Það er enginn heima.
There's nobody home. (enginn — 'no one', masculine nominative)
Ég fer aldrei þangað.
I never go there. (aldrei sits in the ekki slot)
Ég sé ekkert.
I see nothing. / I can't see anything. (ekkert — 'nothing')
Two things worth previewing. First, enginn declines — it changes form for gender, number, and case (enginn, engin, ekkert; engan, enga …), unlike the invariable ekki. Second, Icelandic generally avoids double negation: you use enginn ("nobody") instead of a separate ekki, not alongside it — Ég sé engan ("I see no one"), not Ég sé ekki engan. The negative word itself carries the negation.
Common Mistakes
❌ Ég ekki kem.
Incorrect — in a main clause ekki goes AFTER the finite verb, not before.
✅ Ég kem ekki.
I'm not coming.
This is the classic English "do not" transfer. In a main clause the finite verb comes first, then ekki.
❌ Ég geri ekki vita.
Incorrect — Icelandic has no 'do'-support; negate the real verb directly.
✅ Ég veit ekki.
I don't know.
There is no helper "do" to negate. Put ekki after the actual finite verb (veit).
❌ Ég sé ekki hann.
Unnatural — a pronoun object comes before ekki.
✅ Ég sé hann ekki.
I don't see him.
Light pronoun objects (hann, hana, það) shift to the left of ekki; only full noun phrases stay to its right.
❌ Ég sé ekki engan.
Incorrect — Icelandic avoids doubling ekki with a negative word.
✅ Ég sé engan.
I see no one.
The negative pronoun engan already carries the negation; do not add ekki on top of it.
Key Takeaways
- ekki ("not") is the core negator; in a main clause it sits after the finite verb: Ég kem ekki.
- There is no "do"-support — negate the real verb directly: Ég veit ekki.
- Pronoun objects come before ekki (sé hann ekki); full-noun objects come after it (sé ekki manninn).
- Ekki's position is a diagnostic of clause structure, and it shifts to before the verb in subordinate clauses (its own page).
- Beyond ekki: enginn (no/none, declined), aldrei (never), ekkert (nothing) — and Icelandic avoids stacking these with ekki.

- V2: The Verb-Second RuleA2 — The foundational rule of Icelandic main clauses — the finite verb is always the SECOND constituent, so fronting anything other than the subject forces verb-subject inversion (Í dag fer ég, Þetta veit ég ekki), unlike English which keeps the subject first.
