Questions & Answers about He eivät raportoi ongelmasta.
Why is ongelma (problem) in the elative case (ongelmasta)?
The verb raportoida (to report) acts like a cognitive or communication verb here. Just like with puhua (to speak) and kertoa (to tell), you use the elative case (-sta/-stä) to express what you are talking, thinking, or reporting about.
What is the difference between saying raportoi ongelmasta and raportoi ongelmaa?
Why doesn't the main verb have a plural ending, like raportoivat?
In negative sentences, the negative verb takes the personal ending (here, eivät for they), leaving the main verb in its connegative form. For a Type 2 verb like raportoida, you find the connegative by dropping the final -da, leaving just raportoi.
Can I drop the pronoun He and just say eivät raportoi ongelmasta?
No. While you can often drop the first and second person pronouns (minä, sinä, me, te), you must always keep the third person pronouns (hän, he) in standard Finnish so the sentence's subject remains clear.
