Questions & Answers about Mittaustulos lienee osoittautunut virheelliseksi, koska analysoimme sen liian nopeasti.
Why is virheelliseksi in the translative case?
The verb osoittautua (to turn out to be) is a verb of outcome, which requires the adjective or noun describing that outcome to be in the translative (-ksi) case. In Finnish, the translative case frequently marks the end result of a change or a newly revealed state.
What verb form is lienee and how does it work with osoittautunut?
Lienee is the potential mood of the verb olla (to be), meaning "is probably" or "may be". By combining it with the past participle osoittautunut, the sentence forms the perfect potential tense. Together, they mean "has probably turned out" or "may have turned out".
Why do we use the genitive-looking accusative sen as the object here instead of the partitive sitä?
Because the action was completed. When an action is finished and affects the entire object, Finnish uses a total object. For the pronoun se, the total object form is sen. If the action was ongoing or incomplete ("we were analyzing it"), you would use the partitive sitä.
The word analysoimme is used for both the present and past tense. How do we know it's past tense here?
