1. The challenges of this article

I haven’t kept track of the amount of time I’ve spent on this article, but I think I can safely say that we’re talking about more than a hundred hours. Multiple challenges presented themselves, which slowed my progress significantly.

1.1. Google is even less reliable than I thought

The full list of words ending in -sti, which I started this article with, had more than 3000 words, simply taken from käänteissanakirja. After getting rid of anything that wasn’t an adverb, I fed all the adverbs into Google to find out how common each of these adverbs were. The idea was that I would be able to rely on Google to tell me which adverbs were most used.

I did not expect Google to be accurate – I was just using it as a tool to get an approximate idea of whether the search results were in the thousands, the hundreds of thousands, or the millions. However, Google turned out even more unreliable than I expected. Depending on the day I looked them up, there was often a very large difference in the number of search results. To show you what I was working with, here are some of the progressions I recorded over the many months I spent on this article:

Word Search result progression Explanation
huonosti 10.6 m > 3.9 m > 10.3 m The search results took an unexpected dive of many millions, only to rise back up later.
tarkasti 5 m > 11.7 m > 10.4 m The search results doubled, after which they maintained their number more or less.
erinomaisesti 5 m > 3.8 m > 3 m > 6 m The search results took a dip, then remained stable, only to double again later.
aiheettomasti 44 k > 77 k > 90 k > 83 k The search results steadily climbed then dipped a little at a later search.
intuitiivisesti 171 k > 74 k > 61 k > 198 k The search results took a deep dive only to come back up later.
karmeasti 174 k > 11 k > 12 k The search results suddenly became 15 times less common than initially.
viileästi 132 k > 119 k > 124 k The search results stayed pretty stable through all of my searches.

As you can see, the differences can be very stark. While I never intended to trust Google, it became hard to use it to weed out the rare adverbs.

In order to be included into this article, I decided to set my limit at a minimum of 50 000 search results. For some words, like karmeasti in the list above, this meant they could be very well established as a candidate for this group during one search (174 k is well over 50 k), only to fall short significantly later (11 k isn’t nearly enough).

The final display of the count of each adverb is based on the final Google search I did for each and every one on the 16th of October 2022.

1.2. How am I supposed to display these?

Like for many articles I write, figuring out how I wanted to present these adverbs was a process. I needed to decide if I wanted to add how common these adverbs were, how to order them, whether to add examples or just stick with the list.

I decided I wanted to display a translation for both the base word and the adverb, with an approximation of how common the adverb is. I also really wanted to add example sentences. Originally, I was going to make two giant tables: one which would list all the adjectives and adverbs, and another to list all the examples. Eventually, I decided against these two giant lists and started dividing the adverbs into small groups followed by a small table of example sentences for each group.

However, to keep each list short, it turned out I had to start dividing the adverbs which technically belonged to the same group into subgroups. This was very challenging. You will see below that my divisions are quite arbitrary: randomly picked on a small quality the words in that group might have in common, such as listing adverbs based on adjectives ending in -ma in a different group than other adverbs based on adjectives ending in -a.

The immense amount of adverbs ending in -sesti (based on adjectives ending in -nen) was a major issue. When you scroll down, you will see I have 25 different groups of adverbs ending in -sesti. That’s a crazy number of subcategories, especially when you take into account that ALL of these adverbs are based on an adjective ending in -nen. ALL of them undergo the exact same change in each of the subcategories.

1.3. Motivation problems

Challenge #2 was more of a mental problem. Working for such a long time on one article is taxing. Progress is almost unnoticeable and it’s just word after word of Googling, translating, finding examples, translating the examples, etc.  I lost the motivation to finish this article many times.

The lack of motivation can also be noticeable in this article if you’d go through this systematically and see which adverbs are missing. I did not stick to the “minimum 50 k search results” rule I made up for myself. Oftentimes, I would remove adverbs that should definitely have made it into this article for reasons such as “I can’t think of an example”, “the examples I find for this word are all stupid” or “there is no good translation for this in English”.

The version of this article you’re seeing today is the result of months of work, many frustrated sighs and endless Googling and re-Googling. I hope you find it useful. Personally, I’m just glad it’s over.

2. Adjectives ending in -o/ö/u/y

For all adjectives ending in -o/ö/u/y, you just add -sti to the end of the corresponding adjective. The adjective will undergo consonant gradation and become weak when adding -sti. The 4 groups below are all the same type; they’re just divided up for easier reading.

3. Adjectives ending in -i

Words ending in -i can belong to two groups: they can be so-called “old” and “new” words (click the link to read more). In addition, old words can be divided in two subgroups depending on whether they end in -si or just in -i.

3.1. New adjectives ending in -i

For new words ending in -i, you will add -sti to the basic form of the adjective. No changes happen to the base adjective except for consonant gradation. Words ending in -i will have -sti added to their weak form. You can find the weak form by inflecting the adjective in, for example, the genitive case or the comparative form (e.g. kiltti : kiltin : kiltimpi : kiltisti)

Adjective English Adverb English #
normaali normal normaalisti normally, as usual 7.1 m

3.2. Old adjectives ending in -i

For old words ending in -i, you will change the final -i into an -e- before adding -sti. This is the same change these words undergo in, for example, the genitive case and the comparative form (e.g. suuri : suuren :suurempi : suuresti).

Adjective English Adverb English #
suuri large, great suuresti greatly, considerably 6.5 m

4. Adjectives ending in -a/ä

Finnish has a massive amount of words ending in -a or . In order to keep this article readable, I’ve made some very odd choices when dividing the words in smaller groups. You won’t find any other source that lists adjectives ending in -ma in a separate group. They don’t differ in any way. However, there are enough of them to list them separately and keep these lists fairly short.

4.1. Adjectives ending in -a (two syllables)

For adjectives ending in -a, you just add -sti to the end of the corresponding adjective. This section only contains adjectives without consonant gradation.

Adjective English Adverb English #

4.3. Adjectives ending in -a (consonant gradation)

You can find the weak form by, for example, inflecting the word in the genitive or the T-plural case (e.g. tarkka : tarkan : tarkat : tarkasti). Especially interesting in this group are the words raaka (raa’asti) and arka (arasti).

4.7. Adjectives ending in (two syllables)

For words that undergo consonant gradation, you use the same weak stem you get in the genitive and T-plural form.

For adjectives ending in -e, you will add another -e- before adding -sti. This is the same change words ending in -e undergo in, for example, the genitive and the T-plural cases (e.g. ahne : ahneen : ahneet : ahneesti)

Note how, if your adjective would have consonant gradation, you would need the strong form of the word (e.g. altis would become alttiisti but this word didn’t make it onto the list because it’s too rarely used).

Adjective English Adverb English #

8. Adjectives ending in -as/-äs

Note that I have divided adjectives ending in -as in several subgroups. This only serves the purpose of dividing quite a long list into several smaller groups. It doesn’t mean these groups are somehow different from one another!

8.1. Adjectives ending in -as/äs

Just like if you would be putting these adjectives in the genitive case, you will replace the -as at the end of the adjective with -aa-, after which you add -sti (e.g. runsas : runsaan : runsaasti).

Adjective English Adverb English #
runsas plentiful, abundant runsaasti abundantly, plenty 10.4 m

8.2. Adjectives ending in -as (consonant gradation)

Words ending in -as belong to wordtype B, which means they will undergo consonant gradation. The basic form of words ending in -as will have a weak consonant, while the -sti adverb will have the corresponding strong consonant.

The -as at the end of the word will be replaced by -aa- before the -sti. You can compare the adverb to the genitive or T-plural cases (e.g. hidas : hitaan : hitaat : hitaasti).

Adjective English Adverb English #
hidas slow hitaasti slowly 2.5 m
reipas brisk, vigorous reippaasti briskly, vigorously 1.6 m

Just like if you would be putting these adjectives in the genitive case, you will replace the -as at the end of the adjective with -aa-, after which you add -sti (e.g. kohtelias : kohteliaan : kohteliaasti).

9. Adjectives ending in -ton/tön

Finnish has a large amount of adjectives ending in -ton/tön, which means I’ve opted once again for creating subgroups which don’t especially differ from one another but help break up the long tables into several smaller ones.

The suffix -ton creates an adjective that expresses a lack of something out of a noun. These words undergo quite a drastic change when they’re turned into adverbs, which can be compared to, for example, the genitive case. For example, the adjective loputon will become loputtoman in the genitive case, so you get loputtomasti through that model.

9.1. Adjectives ending in -ton

When your adjective ends in -ton, you will replace this element with -ttoma- followed by the adverb’s -sti.

Adjective English Adverb English #
vaivaton effortless, easy vaivattomasti effortlessly 3.6 m
rajaton limitless rajattomasti unlimitedly 1.5 m
saumaton seamless saumattomasti seamlessly 600 k
tahaton unintentional tahattomasti unintentionally 497 k
armoton merciless, ruthless armottomasti mercilessly, ruthlessly 459 k

ennakkoluuloton open-minded ennakkoluulottomasti without prejudice 271 k
onneton unhappy onnettomasti unhappily, hopelessly 166 k

9.2. Adjectives ending in -ton (based on nouns with consonant gradation)

From the perspective of the adverb, this group doesn’t differ in any way to the previous group of words ending in -ton. However, it can be interesting to look at the noun which the adjective is based on. The follow adjectives are based on a noun which has consonant gradation (e.g. ehto > ehdoton > ehdottomasti; loppu > loputon > loputtomasti).

Adding -sti to the end of the adjectives doesn’t have any effect on the first part of the word; it only requires us to change -ton into -ttoma- before adding -sti.

Adjective English Adverb English #
ehdoton unconditional ehdottomasti absolutely 13.5 m
loputon endless loputtomasti endlessly, indefinitely 893 k
laiton illegal, unlawful laittomasti illegally 724 k

9.3. Adjectives ending in -eeton

These adjectives have -ee- in front of the suffix -ton. This is due to the noun these words are based on: each has a noun ending in -e in its core. This -e which turns into -ee- when you add -ton (e.g. moite > moitteeton > moitteettomasti; tarve > tarpeeton > tarpeettomasti).

Adjective English Adverb English #
moitteeton impeccable moitteettomasti impeccably, immaculately 657 k
tarpeeton unnecessary, needless tarpeettomasti needlessly, unnecessarily 357 k
puolueeton impartial, neutral, fair puolueettomasti impartially, fairly 212 k

9.4. Adjectives ending in -tön

There is zero difference between adjectives ending in -ton vs. -tön, but it allows me to break up these tables into smaller subsections. When your adjective ends in -tön, you will replace this element with -ttömä- followed by the adverb’s -sti.

Adjective English Adverb English #
välitön instant, immediate välittömästi instantly, immediately 17.4 m
vilpitön sincere, candid vilpittömästi sincerely, genuinely 724 k
älytön ludicrous, witless älyttömästi incredibly, a ludicrous amount 300 k

Suomen kieli kiinnostaa minua järjettömästi I’m insanely interested in the Finnish language.

9.5. Adjectives ending in -maton

Adjectives ending in -maton are based on a verb rather than an adjective. For example, huomaamaton is based on the verb huomata and arvaamaton is based on arvata.

Other than the difference in the base word, we change adjectives ending in -maton in exactly the same way as all adjectives ending in -ton: replace the -ton with –ttomasti. It is interesting to see, however, that this causes these adverbs to end in -mattomasti with a double -ma-. The first -ma- is part of the base word, while the second -ma- is part of the adverb.

Adjective English Adverb English #
huolimaton careless, sloppy huolimattomasti carelessly 507 k
huomaamaton unnoticed huomaamattomasti discreetly, imperceptibly 503 k
peruuttamaton irreversible, irrevocable peruuttamattomasti irreversibly, irrevocably 199 k

odottamaton unexpected, unforeseen odottamattomasti unexpectedly 114 k
sopimaton inappropriate, improper sopimattomasti inappropriately, improperly 103 k
auttamaton irredeemable auttamattomasti irrecoverably, irreparably 102 k
arvaamaton unpredictable, uncertain arvaamattomasti unpredictably 96 k

9.6. Adjectives ending in -mätön

Adjectives ending in -mätön have the same origin as adjectives ending in –maton: they’re based on a verb. The only difference is vowel harmony (e.g. auttaa > auttaamaton vs. kärsiä > kärsimätön). Replace the -tön with -ttomä- before adding -sti.

Adjective English Adverb English #

10. Adjectives ending in -nen

Finnish has a very large number of adjectives ending in -nen. Thus, this is another group of adverbs into -sti that gets divided into multiple arbitrary groups which in practice don’t differ from each other at all. Bear with me because there are quite a lot of tables below for words ending in -nen!

We could summarize this whole lower section by saying that adjectives ending in -nen will get -nen replaced with -se- before the suffix -sti.

As such, we could say that tavanomainen (based on the noun tapa “habit”) means “habit-like”, while räjähdysmäinen (based on the noun räjähdys “explosion”) means “explosion-like, similar to an explosion”. Replace -nen by -se- when turning this word into a -sti adverb.

10.8. Adjectives ending in -vainen

The following adverbs are based on adjectives ending in -vainen. In fact, we can analyze most of these words even further: they are all based on a verb (e.g. varoa, luottaa), which has been turned into a VA-participle (varova, luottava), which has been turned into an adjective (varovainen, luottavainen). Finnish has many more such adjectives (e.g. riippuvainen, auttavainen, taipuvainen), but most of these aren’t commonly turned into adverbs.

10.16. Adjectives ending in -illinen which are based on nouns ending in -i (new words)

The journey towards out adverb ending in -illinen starts with a noun (e.g. tyyppi “type” or esimerkki “example). These nouns are new words that end in -i (read more about old and new words ending in -i). When you make an adjective out of this type of noun, you will add -llinen to the end without changing the -i. You will need to pay attention to consonant gradation here. For example, musiikillinen is based on musiikki and laillinen is based on laki. Replace -nen by -se- when turning these adjectives into -sti adverbs!

10.17. Adjectives ending in -ellinen which are based on nouns ending in -i (old words)

Replace -nen by -se- when turning these adjectives into -sti adverbs!

At the very base of these adverbs lies an old noun ending in -i. Nouns ending in -i can belong to two different groups depending on how they inflect in the different cases: old words and new words. When the word is old, the final -i changes into -e when you put the word in the different cases. This same change also takes place when you create an adjective out of them. For example, kielellinen is based on kieli “language” and nimellinen is based on nimi “name”. The adjective täydellinen is based on another adjective: täysi. When the base adjective ends in -si, you will replace -si with -de-.

However, the table below contains two types of words ending in -us/ys: nouns that get “-us > -ukse-” and nouns to get -us > -ude-. This change also takes place when making an adjective out of the nouns. Click the link to find out more about the difference.

11. Adjectives based on the VA-participle

The active present participle is referred to in Finnish as the VA-partisiippi because it ends in –va/vä. It’s based on a verb.

11.1. VA-participle based adjectives ending in -va

For words ending in -va (both participles and regular words like vakava), you just add -sti to the end of the word. This list only has adjectives that are based on verbtype 1 verbs (e.g. jatkua, sujua and toistua).

11.2. VA-participle based adjectives ending in -ttava/ttävä (verbtype 1)

The adjectives there adverbs are based on also come from verbs that belong to verbtype 1. Visually, these all have -ttava at the end because they are based on a verb ending in -ttaa (e.g. yllättää, riittää). Add -sti to the end of the adjective without making any changes.

Adjective English Adverb English #

11.3. VA-participle based adjectives ending in -vä

Due to vowel harmony, these verbs have -vä rather than -va in the present active participle. They do not differ in any way from the previous groups when adding the suffix -sti to them: just glue the suffix to the end of the word!

näkyvä visible näkyvästi visibly, prominently 367 k

12. Adjectives based on the TAVA-participle

The passive present participle is referred to in Finnish as the TAVA-partisiippi (or the TTAVA-partisiippi) because it ends in -(t)tava or -(t)tävä. Add -sti to the end of the adjective to turn it into an adverb.

13. Adjectives ending in -nut/nyt

There are many adjectives that end in -nut/nyt, but they do not all lend themselves to be used as adjectives ending in -sti. My list is particularly short because most of the adverbs that could theoretically exist, do not get more than 50 000 search results in Google.

When making an adverb out of a verb-based adjective ending in -nut/nyt, you replace -nut/nyt with -nee- before adding -sti. This is the same change these words undergo if you were to inflect them in the genitive or T-plural case (e.g. onnistunut : onnistuneen : onnistuneet : onnistuneesti).

Adjective English Adverb English #
onnistunut successful onnistuneesti successfully 4.8 m
hermostunut nervous hermostuneesti nervously 207 k
innostunut enthusiastic, excited innostuneesti enthusiastically, eagerly 198 k
sivistynyt civil, educated sivistyneesti  civilly 96 k


Example sentence Translation
Kuva on lähetetty onnistuneesti. The image has been sent successfully.
Miksi käyttäydyt niin hermostuneesti? Why are you behaving so nervously?
Puhut niin innostuneesti Arista. You talk so enthusiastically about Ari.
He käyttäytyvät sivistyneesti. They behave in a civilized manner.

14. Adjectives based on the TU-participle

The TU-participle is also known as the past passive participle. When turning such adjectives into -sti adverbs, you will need to take consonant gradation into consideration. Add -sti to the weak stem of the word, which is the same stem you have in the genitive and T-plural cases (e.g. odotettu : odotetun : odotetut : odotetusti).

Adjective English Adverb English #
tietty specific, certain tietysti of course 12 m
taattu assured, guaranteed taatusti assuredly, surely 3.9 m
tunnettu known, renowned tunnetusti notoriously, famously 1.3 m
odotettu anticipated odotetusti as expected, as foreseen 599 k
oikeutettu righteous, justified oikeutetusti rightly, rightfully 330 k
harkittu deliberate harkitusti deliberately, thoughtfully 303 k
ansaittu deserved ansaitusti deservedly 234 k
hallittu controlled hallitusti in a controlled manner 209 k
hillitty restrained, temperate hillitysti with restraint, composedly 172 k


Example sentence Translation
Tietysti haluat tulla mukaan. Of course you want to come along.
Tulen taatusti kaipaamaan Aria. I will surely miss Ari.

Näissä juhlissa pitää käyttäytyä hillitysti. At these parties, one must behave with restraint.

15. Adjectives belonging to uncommon word types

This group contains some word types that are quite uncommon. It is a good idea to compare these to the genitive case or the comparative form. For example, lyhyt becomes lyhyesti (compare: lyhyen, lyhyempi) and lämmin becomes lämpimästi (compare: lämpimän, lämpimämpi).

Adjective English Adverb English #
lyhyt short lyhyesti shortly, briefly 3.9 m
kevyt light kevyesti lightly 2.6 m
lämmin warm lämpimästi warmly, heartily 2.4 m
avoin open avoimesti openly 1.9 m
ohut thin ohuesti thinly 191 k


Example sentence Translation
Haluan vain lyhyesti kiittää kaikkia. I just want to briefly thank everyone.
Tätä ei saa ottaa kevyesti. This is not to be taken lightly.
Kannatan sopimusta lämpimästi. I warmly welcome the agreement.
Ari puhuu avoimesti ongelmistaan. Ari speaks openly about his problems.
Huomasitko ohuesti verhotut viittaukset? Did you notice the thinly veiled references?

16. Adverbs based on numbers

Numbers can also be turned into -sti adverbs. The meaning of the number becomes “x times”. Numbers are very old words which have an irregular inflection in most cases. However, the trick of looking at the genitive the T-plural cases (e.g. kaksi : kahden : kahdet : kahdesti) works for these words as well.

Adjective English Adverb English #
kaksi two kahdesti twice 5.6 m
kolme three kolmesti thrice 916 k
viisi five viidesti five times 183 k
tuhat thousand tuhannesti thousand-fold 131 k
kuusi six kuudesti six times 92 k


Example sentence Translation

These are all the adverbs ending in STI I decided to include in this article. Hopefully you get some use out of this article because it surely was a real pain to get this one ready for publishing. Happy studying everyone!
