Questions & Answers about Päätös koskee vakuutusta.

Why is vakuutusta in the partitive instead of vakuutus?

Because the verb koskea in the meaning to concern / to relate to normally takes its object in the partitive.

So:

• vakuutus = insurance / an insurance policy
• vakuutusta = partitive singular of vakuutus

In this sentence, vakuutusta is not showing “some of the insurance” or anything like that. It is there mainly because koskea requires that case in this meaning.

A learner can think of this as a verb pattern:

• koskea + partitive = to concern something

Example:

• Asia koskee minua. = The matter concerns me.
• Päätös koskee vakuutusta. = The decision concerns the insurance / policy.

What form is koskee, and why does it look like that?

Koskee is the 3rd person singular present tense form of the verb koskea.

The subject is päätös (decision), which is singular, so the verb is also singular:

• päätös koskee = the decision concerns

Compare:

• Päätös koskee vakuutusta. = The decision concerns the insurance.
• Päätökset koskevat vakuutusta. = The decisions concern the insurance.

So the ending here matches a singular subject.
