Past tense for verb type 4 (-si-)

Verb Type 4 infinitives end in a vowel followed by -ta/-tä (like tilata or haluta).

To form the past tense, use the marker -si-. You can easily build the past stem from the present tense:

  1. Start with the present tense stem (e.g., tilaa-).
  2. Drop the final vowel (e.g., tila-).
  3. Add -si- and your personal ending (e.g., -n).

Take tilata (to order):

  • Present stem: tilaa-
  • Past stem: tilasi-
  • Past form: tilasin (I ordered)

For the third-person singular (hän, se), simply stop at the -si marker. There is no personal ending or vowel doubling in the past tense.

I ordered the tickets for the festival already in January.
Tilasin liput festivaalille jo tammikuussa.
The band wanted to go on stage early.
Bändi halusi mennä lavalle aikaisin.

Consonant Gradation

Type 4 verbs use the strong grade in all conjugated forms, even though their infinitives are in the weak grade.

  • Present stem: tapaa-
  • Past stem: tapasi-
  • Past forms: tapasin (I met), tapasit (you met)
