Questions & Answers about Avaruusalusta ei olisi laukaistu ilman sinua.
How do we form the negative conditional perfect passive in ei olisi laukaistu?
It is built in three parts. First, the negative word ei. Second, the conditional auxiliary olisi (would be). Third, the passive past participle laukaistu (launched). Together, they mean 'would not have been launched'. Notice that in the passive, the auxiliary olisi never changes to match a person.
Why is the spacecraft (avaruusalusta) in the partitive case here?
In Finnish, the object of a negative sentence is always in the partitive case. Because the action of launching 'would not have been' done, the base word avaruusalus must take the partitive ending to become avaruusalusta.
What are the parts of the compound word avaruusalusta?
The base form is avaruusalus, which is made from avaruus (space) and alus (vessel or ship). Nouns ending in -us often change to -usta in the partitive case, which is exactly what happens here.
Why do we use sinua instead of the basic 'you' form sinä?
The word ilman (without) is a preposition that requires the word following it to be in the partitive case. Therefore, the pronoun sinä changes to its partitive form, sinua.
