Learn Finnish: Onko sovinto edes mahdollinen? - Is a settlement even possible?

Sovinto (settlement, reconciliation) comes from the verb sopia (to agree, to fit). By adding the -nto suffix to the verb root, we create an abstract noun that represents the outcome of the action. So, the result of people agreeing (sopia) is a settlement (sovinto).

What is the difference between sovinto and sopimus, since both translate to forms of agreement?

While both derive from sopia, they have different focuses. Sopimus typically refers to a concrete contract, treaty, or formal agreement. Sovinto, utilizing the abstract -nto suffix, refers more to a reconciliation, a compromise, or the abstract settling of a dispute.

I usually see edes used with negatives, like ei edes (not even). How does it work in this positive question?

When used in a question, edes (even) signals strong doubt or skepticism from the speaker. By asking Onko sovinto edes mahdollinen?, the speaker isn't just asking neutrally if a settlement is possible; they are heavily implying that it seems highly unlikely.

Why is the adjective mahdollinen in the nominative case here instead of the partitive?
