-massa

In the Middle of Doing (-massa)

Level 3

Use -massa/-mässä to say you are 'out' or 'away' doing something right now (e.g., 'I am out eating').

How It Works

The third infinitive inessive is a progressive form that highlights an ongoing action. While the Finnish present tense (e.g., syön) can already mean 'I am eating,' the -massa form adds a specific nuance: it implies the subject is currently occupied with the task, often at a particular place. This form is the 'middle' part of the directional system of local infinitives, alongside -maan (going to do) and -masta (coming from doing).

1. Formation:
To form this, take the strong-grade vowel stem (the same stem used for the 'they' form in the present tense) and add the suffix -ma or -mä followed by the inessive case ending (-ssa/-ssä).

  • lukea (to read) → luke- + -massa = lukemassa
  • syödä (to eat) → syö- + -mässä = syömässä
  • nukkua (to sleep) → nukku- + -massa = nukkumassa (Note: 'kk' stays strong)

2. Usage:
It is most commonly used with the verb olla (to be) to answer the question missä? (where?). It often suggests the person is 'away' doing the action. For example, Hän on syömässä usually means 'He is out at lunch.'

Crucially, this form is also used with verbs of position like istua (to sit), seisoa (to stand), and maata (to lie) to describe an ongoing action performed in that stance. It is also required with the verb käydä (to visit/go and return) when you want to say you went to do something and came back: Kävin kaupassa ostamassa maitoa (I went to the shop to buy milk).

3. Vowel Harmony:
Always remember to apply vowel harmony. Use -massa for back vowels (a, o, u). If the verb contains only front vowels (ä, ö, y) or neutral vowels (e, i), use -mässä. For example: tehdä → tekemässä.

  1. Lapset ovat ulkona leikkimässä.

    The children are outside playing.

    Word by Word: Children are outside playing-in.

    This emphasizes that the children are currently engaged in the act of playing at that specific location (outside).

  2. Olin juuri nukkumassa, kun puhelin soi.

    I was just sleeping when the phone rang.

    Word by Word: I-was just sleeping-in, when phone rang.

    The -massa form emphasizes the state of being in the middle of the process of sleeping.

  3. Hän on käymässä meillä.

    He is visiting us.

    Word by Word: He is visiting-in at-us.

    A very common way to express a temporary visit or stay.

  4. Mies istuu puistossa lukemassa lehteä.

    The man is sitting in the park reading a newspaper.

    Word by Word: Man sits park-in reading-in newspaper-partitive.

    The -massa form is used with verbs of position like 'istua' (to sit) to describe what someone is doing while in that position.

  5. Mitä sinä olet tekemässä?

    What are you doing?

    Word by Word: What you are doing-in?

    Because 'tehdä' contains only neutral vowels (e), it takes the front vowel ending -mässä.

Common Mistakes

  • Using -massa for general habits or long-term states.

    Olen asumassa Helsingissä.
    Asun Helsingissä.

    In Finnish, the simple present tense is used for living somewhere. Using -massa would imply you are in the physical act of 'residing' right this second, which sounds unnatural.

  • Using the weak grade of the stem.

    Olen opimassa suomea.
    Olen oppimassa suomea.

    The third infinitive always uses the strong grade. 'Oppia' (to learn) has a strong stem 'oppi-'.

Learn This First

To understand the 'third infinitive -massa', you need to know how to form the third infinitive stem (-ma/-mä) from a verb. Since this pattern functions like a local case, you must be familiar with the inessive case ending (-ssa/-ssä). Finally, because this pattern typically describes a state of being engaged in an activity, you need to know how to conjugate the verb 'olla' (to be).
