What is the Third Infinitive in Finnish?
In Finnish, verbs have several infinitive forms that serve different grammatical functions. The third infinitive is used to express actions related to purpose, manner, or the means by which something is done. It is often comparable to English expressions like “by doing,” “while doing,” or “in order to do.” This form is essential for constructing sentences that describe how or why something happens.
How is the Third Infinitive Formed?
The third infinitive is created by taking the verb stem and adding the suffix -ma/-mä, depending on vowel harmony. This base form can then be further declined to indicate different cases, most commonly the inessive (where something happens) and the adessive (by means of something).
Forming the Third Infinitive: Step-by-Step
- Start with the verb’s basic form (the infinitive).
- Remove the final -a/-ä from the infinitive.
- Add -ma/-mä to the stem.
For example:
- Lukea (to read) → luke + ma = lukema
- Syödä (to eat) → syö + mä = syömä
- Juosta (to run) → juokse + ma = juoksema
Using the Third Infinitive in Different Cases
The third infinitive is rarely used in its basic nominative form. Instead, it is typically declined in various cases. The two most common are the inessive (-ssa/-ssä) and adessive (-lla/-llä) cases.
1. The Inessive Case (-ssa/-ssä): Expressing “While Doing”
This is used to describe something happening at the same time as another action, similar to “while doing” in English.
- Syödessä (while eating): Syödessäni kuuntelen musiikkia. (While I eat, I listen to music.)
- Lukiessa (while reading): Lukiessa opin uusia sanoja. (While reading, I learn new words.)
2. The Adessive Case (-lla/-llä): Expressing Means or Method
This case is used to show the means or method by which an action is performed, similar to “by doing” or “with doing” in English.
- Kirjoittamalla (by writing): Opin paremmin kirjoittamalla. (I learn better by writing.)
- Puhumalla (by speaking): Kieltä oppii puhumalla. (You learn a language by speaking.)
Possessive Suffixes and the Third Infinitive
When you want to specify the person performing the action, Finnish attaches possessive suffixes to the third infinitive. For example:
- Syödessäni (while I eat)
- Puhuessasi (while you speak)
- Kirjoittaessamme (while we write)
This is particularly useful in complex sentences and is a feature that sets Finnish apart from many other languages.
Common Mistakes and Tips for Learners
- Confusing the infinitive forms: Remember, the third infinitive uses the -ma/-mä suffix, not -minen or others.
- Using correct vowel harmony: Choose -ma for back vowels (a, o, u) and -mä for front vowels (ä, ö, y).
- Practicing with real examples: Try using the third infinitive when describing your daily routine, such as “I learn Finnish by reading” or “While cooking, I listen to podcasts.”

To master the third infinitive, it’s important to see and use it in real contexts. Here are a few practical tips:
