Learn Hardcore Finnish: Minä olen vieläkin väsynyt.

vielä = still, yet
- Olen vielä väsynyt. = I’m still tired.
vieläkin = still, even now, still (after all that)
The little ending -kin often means also, too, even, and here it gives a slightly stronger feeling:
- Olen vieläkin väsynyt. = I’m still tired (even now / surprisingly still).

In many everyday situations, vielä and vieläkin can both work, but vieläkin feels a bit more emphatic or expressive.

Is vieläkin one word or two? What is -kin exactly?

It is written as one word: vieläkin.

The -kin part is an enclitic particle. It:

always attaches to the end of a word, with no space
adds meanings like “also, too, even” or “in spite of everything”, depending on context

Other examples:

minäkin = I also / me too
tänäänkin = today as well / even today
joskuskin = even sometimes

So vieläkin is literally something like “even still”.

Could I change the word order, like Olen vieläkin väsynyt or Vieläkin olen väsynyt? Do they sound natural?

Yes, Finnish word order is quite flexible, and all of these are possible:

Minä olen vieläkin väsynyt.
Neutral, with slight emphasis on minä if context contrasts people.
Olen vieläkin väsynyt.
Very natural and neutral. Common in speech and writing.
Vieläkin olen väsynyt.
Emphasises vieläkin: I am still tired, even now / after all this.
Often used when you’re surprised or annoyed that you’re still tired.
Olen väsynyt vieläkin.
Also possible, but sounds more marked. It can put a bit of emphasis on vieläkin as an afterthought:
I’m tired — still.

The most typical neutral choice is Olen vieläkin väsynyt.

What exactly is väsynyt? Is it an adjective or a verb form?

Väsynyt is used as an adjective here, meaning “tired”.

Grammatically, it comes from a verb:

verb: väsyä = to get tired, to become tired
past participle: väsynyt = (having) gotten tired → tired

Over time, väsynyt is simply treated as the normal adjective tired, used like this:

Olen väsynyt. = I am tired.
Oletko väsynyt? = Are you tired?
Väsyneet lapset nukkuvat. = The tired children are sleeping.

Why doesn’t väsynyt change for gender, like “tired” vs “tired (feminine/masculine)”?

Finnish has no grammatical gender at all. There is:

no masculine/feminine/neuter for nouns
no gender agreement for adjectives
one pronoun hän for he / she

So väsynyt is the same for everyone:

Hän on väsynyt. = He is tired. / She is tired.
Minä olen väsynyt. = I am tired. (regardless of gender)

Adjectives do change for number and case, but not for gender. For example:

singular: väsynyt (I / he / she is tired)
plural: väsyneet (they are tired)

Why is there no word for “a” or “the” before väsynyt?

Finnish has no articles like “a/an” or “the”.

So English phrases such as:

a house, the house
a man, the man
the tired person

are all expressed in Finnish without a separate word:

talo = a house / the house (context tells which)
mies = a man / the man
väsynyt = tired (no “a” or “the” needed)

In Minä olen vieläkin väsynyt, väsynyt just means tired, with no article distinction.

How is the verb olen formed? What are the other forms of olla (to be)?

Olen is the 1st person singular present tense form of the verb olla (to be).

Present tense of olla:

minä olen = I am
sinä olet = you (singular) are
hän on = he/she is
me olemme = we are
te olette = you (plural / formal) are
he ovat = they are

So your sentence follows this pattern:

Minä olen vieläkin väsynyt. = I am still tired.

How would I say “I’m not tired anymore” using this sentence as a model?

You mainly need the negative verb and enää (“anymore”).

En ole enää väsynyt. = I am not tired anymore.

Breakdown:

en = I do not (1st person negative)
ole = base form of “to be” used with the negative
enää = anymore / any longer
väsynyt = tired

So:

Minä olen vieläkin väsynyt. = I’m still tired.
En ole enää väsynyt. = I’m not tired anymore.

Is there an informal or spoken version of Minä olen vieläkin väsynyt?

Yes. In everyday spoken Finnish, especially in southern/urban areas, people often use:

Mä oon vieläkin väsynyt. = I’m still tired. (very common in speech)

Changes:

minä → mä (colloquial “I”)
olen → oon (spoken version of “am”)

Written standard Finnish (books, news, formal texts) prefers:

Minä olen vieläkin väsynyt. or simply
Olen vieläkin väsynyt.

How do I pronounce Minä olen vieläkin väsynyt correctly? Where is the stress?

Key points:

Stress is always on the first syllable of each word:
- MInä Olen VIEläkin VÄsynyt
Vowel lengths matter:
- In vieläkin, all vowels are short here (no double letters).
- In väsynyt, the ä and y are short as written.
Finnish is very phonetic:
- minä ≈ mee-nah (but with short vowels)
- olen ≈ oh-len
- vieläkin ≈ vee-eh-lah-kin (smoothly; ie is a diphthong: vee-eh)
- väsynyt ≈ væ-sy-nyt (with front vowels ä, y, y)

Try to keep the rhythm even and stress only the first syllable of each word.

Is there any difference in feeling between Olen vielä väsynyt and Olen vieläkin väsynyt?

Yes, there is a subtle nuance:

Olen vielä väsynyt.
Neutral “I’m still tired.” It just states the fact.
Olen vieläkin väsynyt.
“I’m still tired (even now).”
Often carries a slight extra emotion — irritation, surprise, or disappointment that you’re still tired despite expectations:
- after sleeping
- after resting
- after some time has passed

Context decides how strong that nuance feels, but vieläkin is usually a bit more expressive than plain vielä.
