The Illative Case: Expressing "To" or "Into"
In Finnish, to talk about going to a destination or into a place, use the illative case. Verbs of movement like mennä (to go), ajaa (to drive), matkustaa (to travel), and lähteä (to leave) require this case.
The illative ending changes depending on the word's final letters.
Multi-Syllable Words Ending in a Long Vowel (-seen)
If a multi-syllable word ends in a long vowel (like -oo), add the ending -seen. This is very common with city names.
One-Syllable Words Ending in a Long Vowel (-hVn)
For short, one-syllable words ending in a long vowel (like puu, tree), or compound words ending in one (like Joensuu), add an -h, repeat the final vowel, and add -n. This creates the -hVn ending.
- Joensuu -> Joensuuhun
- puu -> puuhun
Words Ending in -e
When a word ends in -e, the final vowel doubles to -ee- before adding the -seen ending.
- työhuone (study) -> työhuoneeseen
Words Ending in -us
Words ending in -us, like terveyskeskus (health center), undergo a stem change. The -us changes to -ukse-, and you add -en.
- terveyskeskus -> terveyskeskukseen
Words Ending in a Short Vowel (-Vn)
For most nouns ending in a single short vowel, simply double the final vowel and add -n (often written as -Vn).
- näyttely (exhibition) -> näyttelyyn
- uimahalli (swimming pool) -> uimahalliin
- päiväkoti (daycare) -> päiväkotiin
- kylpylä (spa) -> kylpylään
- kuntosali (gym) -> kuntosaliin
