Negative Questions: Etkö tule? | Finnish Grammar

To turn a negative statement into a yes/no question, Finnish does exactly what it does with a positive one: it attaches -ko/-kö to the fronted verb. The twist is that in a negative clause the "verb" that carries the clitic is the negative verb ei — which inflects for person — while the main verb stays in its bare connegative form. The bigger challenge is not building these questions but answering them, because the yes/no words behave differently after a negative.

Where the clitic goes

The negative verb (en, et, ei, emme, ette, eivät) takes the clitic and moves to the front; the lexical verb keeps its connegative form (the stem with no personal ending: tule, ole, mene, tiedä). See the connegative for that form.

Person	Negative question	English
1sg	Enkö minä tule?	Am I not coming? / Shouldn't I come?
2sg	Etkö sinä tule?	Aren't you coming?
3sg	Eikö hän tule?	Isn't he/she coming?
1pl	Emmekö me mene?	Aren't we going?
2pl	Ettekö te tiedä?	Don't you know?
3pl	Eivätkö he tule?	Aren't they coming?

Etkö tule mukaan?

Aren't you coming along?

Eikö hän ole kotona?

Isn't he at home?

Ettekö te tiedä, missä asema on?

Don't you know where the station is?

Notice the harmony: every negative-verb form (en, et, ei, emme, ette, eivät) contains only e, i or ä — all front or neutral — so the clitic is always -kö: enkö, etkö, eikö, emmekö, ettekö, eivätkö. You will never see -ko here.

For possession and existence, the negative verb still leads, and ole stays connegative:

Eikö sinulla ole autoa?

Don't you have a car?

Enkö minä saa tulla?

Am I not allowed to come?

💡

Build a negative question in two moves: (1) take the ordinary negation — sinä et tule — and (2) front the negative verb with the clitic: etkö sinä tule? The lexical verb never changes; it was already the connegative tule.

Answering a negative question — the crux

Here English fails you. If someone asks "Aren't you coming?" and you say "No", do you mean "no, I'm not" or "no, that's wrong — I am"? English is genuinely ambiguous. Finnish is not, because it has a dedicated word for overturning a negative: kyllä.

The logic is clean:

Agree with the negative (yes, you're right, I'm not) → En. / Ei.
Contradict the negative (no, you're wrong, I am) → Kyllä.

Question	To confirm you're NOT coming	To insist you ARE coming
Etkö tule?	En. (No, I'm not.)	Kyllä (tulen). (Yes, I am.)

Etkö tule? — En.

Aren't you coming? — No (I'm not, you're right).

Etkö tule? — Kyllä (tulen).

Aren't you coming? — Yes I am (you're wrong)!

So here kyllä is not just an emphatic 'yes' — it is the grammatical device for reversing the negative in the question. This is precisely the role German fills with doch and French with si: a special affirmative reserved for contradicting a negative. English has no such word, which is exactly why "aren't you coming? — no/yes" is confusing and why Finns rely on kyllä here.

Eikö sinulla ole nälkä? — Kyllä on!

Aren't you hungry? — Yes I am (I certainly am)!

Eikö kauppa ole auki? — Ei ole.

Isn't the shop open? — No, it isn't (you're right).

eikö niin? — the everyday tag

The frozen phrase eikö niin? ("isn't that so?") turns any statement into a tag question, the way English adds "…right?" or "…isn't it?" It never changes form, whatever the sentence before it.

Sinä tulet huomenna, eikö niin?

You're coming tomorrow, right?

Tämä on hyvä ravintola, eikö totta?

This is a good restaurant, isn't it?

You will also hear the clipped spoken eiks (informal) for eikö: Eiks niin? Beyond this fixed tag, Finnish forms tags in a couple of other ways — those live on the tag questions page.

Common Mistakes

❌ Etkö tule? — Ei. (meaning 'no, you're wrong, I AM coming')

Misleading — to overturn the negative you need kyllä, not ei.

✅ Etkö tule? — Kyllä (tulen).

Aren't you coming? — Yes I am.

❌ Etkö tulet? (leaving the main verb inflected)

Incorrect — after the negative verb the main verb is the connegative: tule.

✅ Etkö tule?

Aren't you coming?

❌ Et tuletko? (clitic on the lexical verb)

Incorrect — the clitic goes on the fronted negative verb: Etkö tule?

✅ Etkö tule?

Aren't you coming?

❌ Etko tule? / Eiko hän ole? (back-vowel clitic)

Incorrect — the negative verb is always front/neutral, so it takes -kö: etkö, eikö.

✅ Etkö tule? / Eikö hän ole?

Aren't you coming? / Isn't he at home?

Key Takeaways

A negative yes/no question fronts the negative verb with the clitic: Etkö? Eikö? Emmekö? — the main verb stays connegative (tule, ole, mene).
Harmony is fixed: the negative verb only has front/neutral vowels, so the clitic is always -kö.
Answering: use en/ei to agree with the negative, kyllä to contradict it.
kyllä after a negative question is a grammatical reversal device, like German doch / French si — not just an emphatic "yes".
eikö niin? is the invariable everyday tag: "…right? / …isn't it?"
