Questions & Answers about Tapausta ei olisi tutkittu ilman räjähdystä.
How do we form the negative conditional perfect passive in "ei olisi tutkittu"?
It is built with three parts: the negative verb ei, the conditional auxiliary olisi (would be), and the passive past participle of the main verb, tutkittu (investigated). Together, they form the meaning "would not have been investigated".
Where is the normal passive marker in "ei olisi tutkittu"? I'm used to seeing endings like "-taan" or "-tiin".
In perfect tenses that use an auxiliary verb (like the conditional olisi), the main verb doesn't take the standard present or past passive endings. Instead, it is put into the passive past participle form, which usually ends in -ttu or -tty. For the verb tutkia, this form is tutkittu.
Objects in passive sentences are usually in the nominative case. Why is tapausta in the partitive?
The rule for negative sentences overrides the standard passive object rule! Because the verb is negative (ei olisi tutkittu), the object of the sentence must be in the partitive case, changing tapaus to tapausta.
Why is the word for explosion, räjähdys, in the partitive case (räjähdystä)?
The word ilman (without) is a preposition that always requires the noun following it to be in the partitive case. Therefore, räjähdys must become räjähdystä.
