Ikke is the workhorse of Danish negation — it is the plain word for "not," and you will use it constantly. The single thing that makes it tricky is placement: where ikke stands depends on the kind of clause it's in. But the good news running through this whole page is that the placement is not a list of arbitrary cases. It is one rule with several surface forms: ikke sits next to the finite verb, on one side in main clauses and the other side in subordinate clauses. Learn to feel which clause type you're in, and ikke falls into place automatically.
Main clauses: ikke comes after the finite verb
In a main clause, ikke stands after the finite (conjugated) verb.
Jeg spiser ikke fisk.
I don't eat fish.
Han kommer ikke i dag.
He isn't coming today.
Vi har ikke tid.
We don't have time.
The pattern is subject – verb – ikke – rest. Notice there is no "do": Danish negates by inserting ikke, never by adding a helper verb. This is the most common position you'll meet, and for simple statements it's all you need.
Subordinate clauses: ikke comes before the finite verb
Here is the shift that surprises English speakers. Inside a subordinate clause — one introduced by at ("that"), fordi ("because"), hvis ("if"), da ("when"), and the like — ikke moves to before the verb.
Hun ved, at jeg ikke spiser fisk.
She knows that I don't eat fish.
Jeg bliver hjemme, fordi jeg ikke har tid.
I'm staying home because I don't have time.
Hvis han ikke kommer, går vi alene.
If he doesn't come, we'll go alone.
Compare the main-clause and subordinate-clause versions of the same idea directly:
| Clause type | Order around the verb | Example |
|---|---|---|
| Main clause | verb – ikke | Jeg spiser ikke fisk. |
| Subordinate clause | ikke – verb | …at jeg ikke spiser fisk. |
Nothing about the meaning changed — only the clause template did. This ikke-before-the-verb position is in fact one of the clearest signals that you're inside a subordinate clause; if you hear ikke land before the verb, you know a linking word came earlier.
Ikke and the fundament: fronting doesn't move ikke
The V2 rule still governs main clauses, so you can front a time word and invert the subject. Ikke stays where it belongs — after the finite verb, which means after the inverted subject.
I dag spiser jeg ikke fisk.
Today I'm not eating fish.
Desværre kommer han ikke til festen.
Unfortunately he isn't coming to the party.
The order is fundament – verb – subject – ikke. Fronting reshuffles the front of the clause, but ikke keeps its place relative to the verb.
Object shift: ikke moves around a pronoun object
Here is a subtle but important interaction. A light pronoun object — ham ("him"), hende ("her"), den/det ("it") — jumps to before ikke. This is called object shift. A full noun object does not move; only an unstressed pronoun does.
Jeg kender ham ikke.
I don't know him. (pronoun 'ham' shifts before ikke)
Jeg kender ikke din bror.
I don't know your brother. (full noun stays after ikke)
Compare the two side by side: with the pronoun ham, the order is kender – ham – ikke; with the full noun phrase din bror, the order is kender – ikke – din bror. The pronoun is "light" and slides forward, hugging the verb; the heavier noun phrase stays put. (For the broader rules, see Order of Objects and Light Elements.)
Scope: sentential vs partial negation
So far ikke has negated the whole clause — this is sentential negation, the default. But ikke can also negate a single constituent, which is partial negation. When ikke immediately precedes a particular phrase, it denies just that phrase, often setting up a correction with men ("but").
Jeg kommer ikke i dag, men i morgen.
I'm not coming today, but tomorrow. (ikke negates 'i dag' specifically)
Det er ikke min bog, men din.
It's not my book, but yours. (ikke negates 'min bog')
In ikke i dag ("not today"), the negation targets the time phrase alone: the coming still happens, just not today. This is why position carries meaning — ikke tends to negate what comes right after it. The finer points, including where the negated phrase is ambiguous, are on Negation Scope and Position.
One rule, several surface forms
Step back and the whole page collapses to a single idea. Ikke attaches to the finite verb. The clause type decides which side:
- Main clause: after the verb — Jeg spiser *ikke fisk.*
- Main clause with fronting: still after the verb (and after the inverted subject) — I dag spiser jeg *ikke fisk.*
- With a pronoun object: the pronoun shifts in front of ikke — Jeg kender ham *ikke.*
- Subordinate clause: before the verb — …at jeg *ikke spiser fisk.*
- Partial negation: directly before the constituent it denies — …*ikke i dag, men i morgen.*
Five surface forms, one underlying principle. You are not memorising cases; you are tracking the finite verb and the clause type.
Common mistakes
❌ Hun ved, at jeg spiser ikke fisk.
Incorrect — used main-clause order inside a subordinate clause; ikke must precede the verb.
✅ Hun ved, at jeg ikke spiser fisk.
She knows that I don't eat fish.
❌ Jeg ikke spiser fisk.
Incorrect — in a main clause, ikke goes AFTER the finite verb, not before it.
✅ Jeg spiser ikke fisk.
I don't eat fish.
❌ Jeg kender ikke ham.
Incorrect — an unstressed pronoun object (ham) shifts before ikke.
✅ Jeg kender ham ikke.
I don't know him.
❌ Jeg gør ikke lide kaffe.
Incorrect — imported English do-support; Danish negates with ikke alone.
✅ Jeg kan ikke lide kaffe.
I don't like coffee. (literally: I can't like coffee — the fixed Danish expression)
Key takeaways
- Ikke means "not" and attaches to the finite verb.
- Main clause: ikke comes after the verb. Subordinate clause: ikke comes before the verb.
- Fronting reshuffles the clause but leaves ikke in place relative to the verb.
- An unstressed pronoun object shifts before ikke (object shift); a full noun stays after it.
- Ikke can negate the whole clause (sentential) or just the constituent right after it (partial), as in ikke i dag.
- Danish never uses do-support — negate with ikke, not a translated "do."
