Finnish Filler Words That Make You Sound Fluent
Written Finnish and spoken Finnish are noticeably different, and casual speech is full of small filler words that give you time to think. This guide covers the ones Finns actually say, how they work, and how to use them without leaning on them too hard.

What's in this guide
Spoken Finnish is its own thing
One of the first surprises for Finnish learners is that the colloquial spoken language, puhekieli, differs a fair amount from the tidy written form in textbooks. Fillers live almost entirely in that spoken world, so hearing them in real conversation matters more than reading about them. They are the small sounds and short words that buy you a moment to think while your speech keeps flowing.
Start with the pure hesitation sounds, which mean nothing on their own:
- öö (uh) = the basic thinking sound, like the English "uh"
- no (noh) = "well", a soft opener before a reply
Use öö to fill a short gap while your brain works, and no to ease into an answer, similar to starting an English sentence with "Well...". The rest of this guide covers the real words that act as fillers and connectors. Learn a few of them well and your Finnish will sound spoken and relaxed rather than read off a page.
Niinku, the Finnish "like"
If you learn only one Finnish filler, this is the one you will hear most.
- niinku or niin ku (NEEN-koo) = "like", from niin kuin
Niinku is a shortened, spoken form of niin kuin, which means "like" or "as". As a filler it works almost exactly like the English "like": you slot it in before an idea you are about to explain or an example you are reaching for. A Finn might say the equivalent of "it was niinku really weird." It is extremely common in casual speech, especially among younger people. The honest warning is the same as for "like" in English: it is very easy to overuse. Lean on it too hard and every clause gets one, which sounds careless. In a relaxed chat, one or two per thought is natural. In a formal presentation or interview, cut it almost entirely.
Tota and tuota, the classic hesitation words
When you need a beat to gather your thoughts, two closely related words carry you.
- tota or tota noin (TOH-tah) = "um", "well", or "like"
- tuota (TOO-oh-tah) = "um" or "that", a placeholder
Tota, often stretched into tota noin, is the classic Finnish stall, the sound you make while deciding how to phrase something, like a drawn out "well..." in English. Tuota is a close relative that works the same way, a spoken placeholder while you search for the next word. You will hear both at the start of replies and mid sentence when someone pauses to think. They are casual and very natural. The main thing to watch is that they are meant to bridge a short gap, not to open every single sentence. A well placed tota sounds thoughtful, while a tota before every clause turns into a habit your listener will start to notice.
Siis and niin, for clarifying and agreeing
Two short words help you restate an idea or signal agreement.
- siis (sees) = "so" or "I mean"
- niin (neen) = "so", "yeah", or "right"
Siis introduces a clarification or a conclusion, similar to "so" or "I mean" in English. You use it when you want to restate something more clearly or draw things together. Niin is a workhorse that can mean "so" to move a thought forward, or act as "yeah" and "right" to show you are listening and agreeing. You will hear niin used as a quiet backchannel while someone else talks, the way English speakers murmur "right" or "mm hmm." Both fit casual and semi formal speech. A common learner mistake is starting every sentence with siis, which quickly sounds mechanical, so vary your openers and let it land where it genuinely signals a summary.

Say a sentence, hear where it went wrong, and try again, all in seconds. SPAIKING gives you a patient partner that never sighs at your mistakes.
Silleen, kai and justiin
A few more fillers add nuance, from vagueness to certainty.
- silleen (SIL-layn) = "like" or "kinda"
- kai (kigh) = "maybe" or "I guess"
- justiin (YOOS-teen) = "exactly" or "just so"
Silleen softens a description, similar to "kinda" or "in a way" in English, and it appears in relaxed speech when you are being loose about the details. Kai adds gentle uncertainty, like "I guess" or "maybe", letting you commit to something only halfway. It is handy when you are not fully sure and want to sound honest rather than overconfident. Justiin goes the other direction, expressing agreement or precision like "exactly" or "just so." All three belong to casual speech. Kai in particular is useful because hedging politely is such a common need in conversation. Use them to color your speech, but keep them light so they add nuance rather than clutter.
Formal versus casual, and common mistakes
Nearly all of these fillers belong to spoken, colloquial Finnish. In formal writing, a presentation, or an official setting, the language shifts toward the tidy written form, and you should thin the fillers out, keeping mainly a plain hesitation sound and perhaps siis. Niinku and silleen especially mark relaxed, everyday talk. Matching your fillers to the setting is part of sounding fluent rather than just casual.
The biggest mistake learners make is overusing niinku, exactly as English speakers overuse "like." Once it appears in every clause, it stops helping and starts distracting. Another slip is opening every sentence with the same word, whether no, siis, or tota, until the rhythm feels mechanical. Aim for one filler per thought and vary which one you reach for. Listen to how Finns pace them in real speech, since the timing matters as much as the word itself.
How to make them stick
Reading a list of fillers will not put them in your mouth at the right moment. They stick when you hear them in real speech and imitate the timing. Watch Finnish vlogs, interviews, or shows and notice how often niinku, tota and niin appear, then pause and repeat the phrase out loud, copying the rhythm.
The real test is speaking. Try narrating your day in simple spoken Finnish and let yourself drop in tota or niinku whenever you pause, instead of freezing in silence. Practicing conversations out loud, whether with a patient friend or an AI speaking partner that talks back, is where these words move from something you recognize into speech you actually produce. Start with just two or three, use them until they feel effortless, then add more. A light, natural touch will always beat cramming every filler into one sentence.
