Questions & Answers about Meidän täytyy korvata fossiiliset polttoaineet aurinkopaneeleilla ja tuulivoimalla.
How would we rewrite the end of this sentence using the niin ... kuin ... -kin structure from this lesson?
You would use it to emphasize replacing fuels with both solar and wind power. The -kin suffix attaches to the very end of the second item. Because the words are in the adessive case, the phrase becomes: ...niin aurinkopaneeleilla kuin tuulivoimallakin.
Why do aurinkopaneeleilla and tuulivoimalla take the adessive case (-lla / -llä)?
The verb korvata (to replace) uses the adessive case to express the instrument or means being used as the replacement. While English uses the preposition 'with', Finnish attaches the adessive ending to the things taking over the job.
Why is the object fossiiliset polttoaineet in the nominative plural?
This is a strict rule for necessity verbs like täytyy. Total objects for these verbs are never in the genitive-accusative; instead, a plural total object takes the nominative form. If the sentence meant replacing only some fossil fuels, it would take the partitive plural: fossiilisia polttoaineita.
As a refresher, why is it meidän täytyy instead of a conjugated verb like 'me täydymme'?
Necessity verbs like täytyy and pitää use a unique sentence structure. The person who has to do the action is placed in the genitive case (meidän), and the verb is frozen in the third-person singular, meaning it never conjugates to match the actor.
