mennä + Illative

Going into (Mennä + Illative)

Level 1

In Finnish, when you 'go' somewhere, you don't just use a preposition like 'to'. Instead, you change the ending of the destination word to the illative case (the 'into' form) to show you are moving toward it.

How It Works

When using mennä, you must choose the correct destination ending based on the word type, while always following vowel harmony. These rules apply to the singular illative (plural examples include kouluihin, taloihin, naisiin, and huoneisiin: choose the plural stem and its word-type-specific ending rather than attaching one form to every noun):

First, always find the inflectional vowel stem of the word before adding the ending, rather than just adding it to the dictionary form.

  • Short Vowel Words: Double the final vowel and add -n (e.g., koulu → kouluun, nalle → nalleen).
  • One-Syllable Words ending in a long vowel or diphthong: Add -h + vowel + -n (e.g., maa → maahan, suo → suohon, yö → yöhön).
  • Multisyllabic words with a long vowel stem, including many dictionary forms in -e such as huone: These take the -seen ending (e.g., huone → huonee- → huoneeseen, Espoo → Espooseen).
  • 'Old -i' Words vs 'New -i' Words: Older Finnish words like kieli (language) change the 'i' to 'e' first (e.g., kieleen). Words ending in '-si' like vesi (water) change 'si' to 'te' (e.g., veteen). However, 'New -i' words (newer words and loanwords) simply double the 'i' (e.g., Helsinki → Helsinkiin, taksi → taksiin).
  • Foreign Loanwords (Minor Exception): Polysyllabic words ending in a diphthong take the -hVn ending, where V is the last vowel of the diphthong (e.g., Macau → Macauhun).

Crucially, the illative case uses the strong stem. This means ordinary direct-gradation words do not weaken (e.g., kauppa stays strong as kauppaan), while inverse-gradation words use their strong vowel stem (e.g., rakas → rakkaaseen).

Note that pronouns are highly irregular with mennä + illative. Personal pronouns: minä → minuun, sinä → sinuun, hän → häneen, me → meihin, te → teihin, he → heihin. Demonstrative/interrogative pronouns: tämä → tähän, tuo → tuohon, se → siihen, mikä → mihin.

While mennä often takes the illative for 'into' movement, it takes the allative for open spaces or some cities (e.g., mennä torille - to go to the market square, mennä Tampereelle).

Other Verbs with Destinations
The illative answers mihin? and also occurs with tulla (come), saapua (arrive), muuttaa (move), and jäädä (stay/remain): Hän jäi huoneeseen. The location still decides inner versus outer case: saapua kouluun but saapua torille. Do not replace the stem rule with “every final-e word takes -seen”: nalle → nalleen is a different type.

Examples (6)

  1. Minä menen kauppaan.

    I am going to the shop.

    Word by Word: I go into-shop.

    The word 'kauppa' keeps its double 'pp' (strong grade) and doubles the final 'a' to form the illative.

  2. Menen huomenna kouluun.

    I am going to school tomorrow.

    Word by Word: I-go tomorrow into-school.

    Koulu becomes kouluun by doubling the final 'u' and adding 'n'.

  3. Hän meni kotiin.

    He/she went home.

    Word by Word: He/she went into-home.

    Kotiin is the familiar illative of koti, with lengthened i plus n. Compare static kotona and source kotoa, which use different conventional local forms.

  4. Lapset menevät ulos leikkimään.

    The children go outside to play.

    Word by Word: Children go out to-play.

    Here, 'mennä' is paired with the 3rd infinitive 'leikkimään' to show the purpose of going.

  5. Me menemme Porvooseen.

    We are going to Porvoo.

    Word by Word: We go to-Porvoo.

    Proper nouns ending in long vowels, like Porvoo, use the -seen ending for the illative.

  6. He menevät naimisiin.

    They are getting married.

    Word by Word: They go into-marriages.

    The abstract expression 'mennä naimisiin' (to get married) uses the plural illative form.

Common Mistakes

  • Using the weak stem (consonant gradation) in the illative.

    Menen kaupaan.
    Menen kauppaan.

    The illative case always requires the strong stem. Do not apply consonant gradation to remove the extra 'p' from 'kauppa'.

  • Using the plural illative when a singular is intended.

    Menen vesiin. (Meaning: into the water as one substance.)
    Menen veteen.

    Vesi has singular stem vete- and illative veteen. Vesiin is a real plural form, used for waters or bodies of water, so the issue is the intended number and meaning.

  • Using the inessive case (-ssa) for movement.

    Menen kaupassa.
    Menen kauppaan.

    'Kaupassa' means you are already inside the shop. To show movement toward it, you must use the illative 'kauppaan'.
