Learn Finnish: Kaikki hankkeet rahoitettaneen pian. - All projects will probably be financed soon.

It is built from the verb rahoittaa (to finance). For type 1 verbs, you take the weak stem (rahoita-), change the final -a to -e- (rahoite-), and add the passive potential marker -ttaneen. This gives us rahoitettaneen.

Why is the object Kaikki hankkeet in the nominative plural, rather than the partitive or genitive?

The object of a passive verb in Finnish follows special rules. Plural objects of a passive verb take the regular nominative plural form, which is hankkeet. Since the financing is a complete, total action applied to all the projects, this nominative plural is used instead of the partitive case.

Is the verb rahoittaa related to the word raha (money)?

Yes, it is directly derived from raha. The suffix -oittaa is often used to turn a noun into a transitive verb meaning to provide with or to equip with that noun. Therefore, rahoittaa literally means to provide with money, which translates naturally to financing or funding.

The translation says 'will probably be', but is this a future tense?

Finnish does not have a dedicated future tense. The potential mood here is in the present tense, which can refer to a probability happening right now or in the future. The adverb pian (soon) provides the necessary context to make it a future probability.
