Agent Participle in Finnish

In Brief

The Finnish agent participle (agenttipartisiippi) expresses that the noun it describes is the result or object of an action performed by a named doer: äidin tekemä kakku means “a cake made by mother.” The doer comes first in the genitive case (the form often ending in -n), while the verb takes -ma/-mä and agrees with the noun. With a personal pronoun, standard Finnish also adds a possessive suffix: minun tekemäni kakku “the cake made by me.”

Overview

A participle is a form made from a verb that can describe a noun, much like an adjective. English uses forms such as “written” in “a written message.” Finnish has several participles; the agent participle is special because it combines the action with an explicitly identified agent—the person, group, institution, or sometimes thing that performs it.

This B2 structure often replaces a relative clause. Finnish can turn kakku, jonka äiti teki “a cake that mother made” into the more compact äidin tekemä kakku. It is particularly useful in news, instructions, reviews, academic writing, and other information-dense texts, but ordinary expressions such as itse tehty and minun tekemäni occur in everyday language too.

English normally puts the doer after a passive participle with “by”: “a book written by Leena.” Finnish reverses that order and uses no word corresponding to “by”: Leenan kirjoittama kirja. The pattern is therefore best learned as a complete unit rather than translated word by word.

How It Works

The basic pattern

The central structure is:

doer in the genitive + verb stem + -ma/-mä + noun

Full clause	Agent-participle phrase	Meaning
Äiti teki kakun.	äidin tekemä kakku	a cake made by mother
Opettaja antoi tehtävän.	opettajan antama tehtävä	a task given by the teacher
Leena kirjoitti kirjan.	Leenan kirjoittama kirja	a book written by Leena

The genitive is a Finnish case—a form that marks relationships such as possession and, here, the doer. For many nouns it has -n: äiti → äidin, opettaja → opettajan, Leena → Leenan. Stem changes still apply, so you must use the noun’s real genitive form rather than simply attaching -n mechanically.

The suffix follows vowel harmony: use -ma with back-vowel words and -mä with front-vowel words. In practice, learn the participle from the verb’s appropriate stem:

Infinitive	Agent participle	Example phrase	English
tehdä	tekemä	isän tekemä pöytä	a table made by father
antaa	antama	lääkärin antama neuvo	advice given by the doctor
kirjoittaa	kirjoittama	toimittajan kirjoittama artikkeli	an article written by a journalist
nähdä	näkemä	minun näkemäni elokuva	a film seen by me
ostaa	ostama	yrityksen ostama rakennus	a building bought by the company
löytää	löytämä	lapsen löytämä avain	a key found by the child

Because Finnish verb stems can change, forms such as tekemä and näkemä should not be guessed from the English translation. Connect each form directly to its infinitive: tehdä → tekemä, nähdä → näkemä.

The participle agrees with the noun

The agent remains in the genitive, but the participle behaves like an adjective. It takes the same case (a noun or adjective ending that shows its role in the sentence) and number as the noun it describes.

Function	Finnish	English
Basic singular	äidin tekemä kakku	a cake made by mother
Genitive singular	äidin tekemän kakun hinta	the price of the cake made by mother
Partitive singular	Söin äidin tekemää kakkua.	I ate some cake made by mother.
Inessive singular	äidin tekemässä kakussa	in the cake made by mother
Nominative plural	äidin tekemät kakut	the cakes made by mother
Partitive plural	äidin tekemiä kakkuja	cakes made by mother / some cakes made by mother

Notice that äidin does not change across these examples. It marks who did the making. The endings on tekemä and kakku change together: tekemä kakku, tekemän kakun, tekemää kakkua, tekemät kakut, tekemiä kakkuja.

Personal pronouns require a possessive suffix

When the doer is a personal pronoun, careful standard Finnish normally marks the person twice: with the pronoun’s genitive and with a possessive suffix (an ending showing whose action it is) on the participle.

Doer	Standard form	Meaning
minä	minun tekemäni	made by me
sinä	sinun tekemäsi	made by you
hän	hänen tekemänsä	made by him/her
me	meidän tekemämme	made by us
te	teidän tekemänne	made by you (plural or formal)
he	heidän tekemänsä	made by them

The suffix remains attached when the participle declines: minun tekemäni kakku, minun tekemässäni kakussa, meidän kirjoittamamme raportit. A noun agent does not trigger this suffix: Leenan kirjoittama raportti, not Leenan kirjoittamansa raportti.

The pronoun can sometimes be omitted when the person is clear: tekemäni virhe “the mistake made by me,” kirjoittamamme raportti “the report written by us.” The suffix itself identifies the doer.

What time does it express?

The agent participle does not contain a normal tense ending. It usually presents the action as already completed or as producing the noun being discussed: Mikon rakentama talo is a house that Mikko built. The surrounding sentence supplies the time:

• Tämä on Mikon viime vuonna rakentama talo. — “This is the house Mikko built last year.”
• Näemme huomenna palkinnon voittajan suunnitteleman työn. — “Tomorrow we will see the work designed by the prize winner.”

Do not treat -ma/-mä as simply a Finnish past tense. It is a noun-modifying form, and time words or the main verb establish when the action happened.

The negative counterpart: -maton/-mätön

Forms in -maton/-mätön commonly express that the action has not occurred or that something lacks the quality implied by the verb. They decline like adjectives, with the stem -mattoma-/-mättömä- in many case forms.

Verb	Negative form	Example	Meaning
lukea	lukematon	lukematon kirja	an unread book
maksaa	maksamaton	maksamaton lasku	an unpaid bill
ratkaista	ratkaisematon	ratkaisematon ongelma	an unresolved problem
tuntea	tuntematon	tuntematon henkilö	an unknown person

This negative form does not normally identify a doer as neatly as the positive agent-participle pattern does. If “not done by X” is important, a full clause is often clearer: kirja, jota en ole lukenut “a book that I have not read.” Also, many -maton/-mätön forms have become established adjectives, so tuntematon often simply means “unknown,” not “not known by a particular agent.”

Examples in Context

Finnish	English	Note
Söimme äidin tekemää kakkua.	We ate some cake made by mother.	The participle and noun are partitive.
Tämä on opettajan antama tehtävä.	This is the task given by the teacher.	Basic singular form.
Luin Leenan kirjoittaman artikkelin.	I read the article written by Leena.	kirjoittaman artikkelin is genitive/total-object form.
Poliisi löysi varkaan käyttämän auton.	The police found the car used by the thief.	The doer varkaan is genitive.
Pidätkö minun ottamastani kuvasta?	Do you like the photo I took?	Elative agreement: ottamastani kuvasta.
Korjasimme tekemämme virheet.	We corrected the mistakes we had made.	The suffix -mme identifies “us.”
Hänen suunnittelemansa talo valmistui viime vuonna.	The house designed by him/her was completed last year.	Pronoun plus possessive suffix.
Museossa on paikallisten taiteilijoiden tekemiä veistoksia.	The museum has sculptures made by local artists.	Partitive plural: tekemiä veistoksia.
Yrityksen kehittämä sovellus on helppokäyttöinen.	The application developed by the company is easy to use.	An institution can be the agent.
Nämä ovat lasten piirtämät kuvat.	These are the pictures drawn by the children.	Nominative plural agreement.
En löytänyt maksamatonta laskua.	I did not find an unpaid bill.	Negative -maton form, declined in the partitive.
Ongelma on edelleen ratkaisematon.	The problem is still unresolved.	Predicative adjective use.
Tapasimme entuudestaan tuntemattoman henkilön.	We met a person previously unknown to us.	tuntematon is a lexicalized adjective.

Common Mistakes

Using a “by” phrase instead of the genitive

• Wrong: kakku tehty äidiltä
• Right: äidin tekemä kakku
• Why: The agent-participle construction places the doer before the participle in the genitive. Finnish does not copy English “made by mother” word order here.

Leaving the agent in the basic form

• Wrong: opettaja antama tehtävä
• Right: opettajan antama tehtävä
• Why: The doer must be genitive: opettaja → opettajan.

Forgetting agreement

• Wrong: Söin äidin tekemä kakkua.
• Right: Söin äidin tekemää kakkua.
• Why: The participle agrees with kakkua in the partitive case. Treat it as an adjective attached to the noun.

Omitting the possessive suffix in standard Finnish

• Less suitable in formal writing: minun tekemä kakku
• Standard: minun tekemäni kakku
• Why: A personal-pronoun agent normally requires the corresponding possessive suffix. The shorter pattern is common in colloquial speech, especially as mun tekemä kakku, but it is not the safest model for formal writing.

Adding a possessive suffix after a noun agent

• Wrong: Leenan kirjoittamansa kirja
• Right: Leenan kirjoittama kirja
• Why: Ordinary noun agents such as Leenan do not require a possessive suffix. The suffix belongs with personal-pronoun agents such as hänen kirjoittamansa.

Treating every -maton word as a literal passive phrase

• Misleading analysis: tuntematon henkilö = “a person not known by a named doer”
• Better: tuntematon henkilö = “an unknown person”
• Why: Many negative forms function as independent adjectives. Use a full relative clause when you need to state exactly who did not perform the action.

Usage Notes

Agent participles are productive and natural, but they are more concentrated in written Finnish than in relaxed conversation. News headlines, product descriptions, official decisions, and academic texts favor compact phrases such as hallituksen tekemä päätös “the decision made by the government.” In speech, a relative clause may feel easier: päätös, jonka hallitus teki.

The structure can be used attributively, directly before a noun, or predicatively after olla: Tämä pöytä on isän tekemä “This table was made by father.” The predicative version is especially useful when identifying the maker of an object.

English does not always use a passive translation. Minun ottamani kuva is naturally “the photo I took,” not necessarily “the photo taken by me.” Translating the Finnish phrase into an English relative clause often produces smoother English while preserving the same relationship.

Do not confuse the agent participle with the third infinitive, even though both contain -ma/-mä. In Menen syömään “I am going to eat,” syömään follows a motion verb and does not describe a noun. In lapsen syömä omena “the apple eaten by the child,” syömä modifies omena and has a genitive agent.

Beyond the Basics / Advanced Use

Contrast with other participles

Choosing the right participle depends on what you want to foreground.

Form	Example	Main idea
Active present -va/-vä	kirjaa lukeva opiskelija	the student who is reading a book
Passive past -ttu/-tty	eilen luettu kirja	a book that was read; no agent needs to be named
Agent -ma/-mä	opiskelijan lukema kirja	a book read by the student; the agent is named
Negative -maton/-mätön	lukematon kirja	a book that has not been read

The contrast between luettu kirja and opiskelijan lukema kirja is especially useful. Both can refer to a book that was read, but only the agent participle builds the reader into the noun phrase.

Long agent phrases

The genitive agent can be more than one word:

• Suomessa asuvan tutkijan kirjoittama artikkeli — “an article written by a researcher living in Finland”
• kaupungin viime vuonna perustaman työryhmän laatima raportti — “a report prepared by the working group established by the city last year”

Such nesting is grammatical, but several participles and genitives in a row can become hard to process. Formal Finnish uses these structures readily; clear modern prose often replaces an overloaded phrase with one or more relative clauses.

Ambiguity and information structure

A genitive before a noun can express possession, while a genitive before an agent participle expresses the doer. In Marian kirjoittama kirja, Maria is the writer; the phrase does not by itself say that she owns the book. Context usually makes this clear.

The agent need not always be human. Organizations and natural forces can perform actions: yhtiön kehittämä menetelmä “a method developed by the company,” myrskyn kaatama puu “a tree brought down by the storm.” What matters is that the genitive element can be understood as causing or carrying out the verb’s action.

Practice Tips

1. Convert relative clauses in both directions. Start with kirja, jonka Leena kirjoitti and produce Leenan kirjoittama kirja. Then reverse the process. This makes the agent and the modified noun easy to identify.
2. Decline the whole pair. Practice a short series: tekemä työ, tekemän työn, tekemää työtä, tekemässä työssä, tekemät työt, tekemiä töitä. Say the participle and noun together so agreement becomes automatic.
3. Separate noun and pronoun agents. Make paired cards such as Leenan tekemä versus hänen tekemänsä. This directly targets the possessive-suffix rule that learners most often miss.
