The translative case (ending in -ksi) is used to express a scheduled time, deadline, or intended duration. Here, it shows that the proposal is being scheduled or postponed 'for Tuesday'.

Does the verb jättää often trigger the translative case like this?

Yes! When you use verbs like jättää (to leave) or siirtää (to move or postpone) to reschedule an event for a later time, the target time takes the translative case.

Why does the object lopullisen ehdotuksen end in -n?

This is the total object of the sentence. Because the action of leaving the proposal is viewed as a fully completed action, the singular object takes the accusative case, which looks identical to the genitive case ending in -n.

How does the base word lopullinen change into lopullisen?

Adjectives must match the case of the noun they describe, so it needs the accusative -n ending. For words ending in -nen, the stem changes: you replace the -nen with -se- before attaching the case ending.

Why does the English translation say 'We will leave' when jätämme is in the present tense?
