Grammar Rule in 30 Seconds
In Finnish, double consonants are held twice as long as single ones; missing this changes the meaning of your words entirely.
- Single consonants are short: 'tuli' (fire).
- Double consonants are long: 'tulli' (customs).
- Always hold the sound for a full beat, like a musical rest.

Meanings
Finnish uses consonant length to distinguish between different words. A double consonant (geminate) requires a longer duration of the sound.
Meaning distinction
Changing the length of a consonant creates an entirely different word.
“Muta (mud)”
“Mutta (but)”
Grammatical gemination
Certain grammatical cases force a consonant to become long.
“Kaupunki -> Kaupungissa”
“Talo -> Talloon”
