Use the negative passive potential to say that something probably won't be done, or is unlikely to happen. You will frequently see this in official contexts, like news about canceled infrastructure projects.
To form the negative passive potential, use the negative word ei followed by the passive potential verb stem.
The marker for this stem is -ttane / -ttäne or -tane / -täne. It is exactly the same as the affirmative form (e.g., rakennettaneen), just without the final -en.
The easiest way to construct it is to start with the passive past participle (e.g., rakennettu), remove the final -u or -y, and add -ane or -äne:
- rakennettu (built) → rakennett-
- jatkettu (extended) → jatkett-
- aloitettu (started) → aloitett-
Vowel Harmony
As always, apply vowel harmony: if the word contains front vowels (ä, ö, y) or only neutral vowels (e, i), use the ending -äne instead of -ane.
- hyväksytty (approved) → hyväksytt-
Discussing Canceled Projects
This form is extremely common when discussing funding, costs, and projects that are unprofitable or shelved.
