Vowel Length: Short vs Long

Grammar Rule in 30 Seconds

In Finnish, holding a vowel sound twice as long changes the meaning of a word entirely.

  • A single vowel is short: 'tuli' (fire).
  • A double vowel is long: 'tuuli' (wind).
  • Always pronounce every letter you see; never skip a double vowel.
V = short sound, VV = long sound (V + V)

Meanings

Finnish uses vowel length to distinguish between different words. A double vowel is a distinct phoneme that must be held for the duration of two short vowels.

Semantic Distinction

Changing the length of a vowel creates a completely different word.

“Muta (mud) vs. Muuta (change)”

“Taka (back) vs. Takka (fireplace - note: consonant length)”
