eiku
/ˈeiku/
No wait. I mean. Scratch that. Written ei kun One word for taking back the last thing you said
Quick answer
Eiku means no wait, or I mean. It cancels what you just said and puts the correction next.
- The comprehensive grammar lists it among the particles used for self-repair, with tai, siis and niinku.
- It corrects yourself, not the other person - for that you need ei vaan or eiku sä sanoit.
What eiku means
Eiku undoes your own last few words. It signals that a correction is coming, and the important part of the sentence is whatever follows it.
It comes from ei kun, no but, and speech has fused the two into one unit.
How Finns actually use eiku
Fixing a fact mid-sentence. Se oli kolmelta, eiku neljältä means it was at three, no, at four.
Fixing a word: mä otan kahvin, eiku teen.
Softening a whole retraction: eiku unohda koko juttu - actually, forget the whole thing.

ei kun on paper, eiku out loud
One of the written-and-spoken pairs - every word on this site that exists in both forms is in that table, beside the change between them.
Why ei kun became eiku
Written you would separate it - ei, kun tarkoitin - or rewrite the sentence entirely, which is what writing lets you do.
Eiku exists because speech cannot be rewritten. It is the spoken equivalent of a backspace, and it belongs to a small set of particles that do that job.
The rule behind eiku
The change in eiku is not a one-off. It is one of the regular changes between written and spoken Finnish, and it applies well beyond this word.

| Writtenniin kuin | Spokenniinku | What changedThe same fusion on the other high-frequency pair, and the source of the filler. |
| Writtenettä | Spokenet | What changedThe commonest conjunction in the language, worn down to two letters. |
| Writtensitten | Spokensit | What changedFinal syllable gone: sitten, sitte, sit. |
| Writtenkun | Spokenku | What changedFinal n drops, which is what lets it glue onto the word in front. |
