uskoisivat

uskoisivat is the conditional mood, third-person plural form of the Finnish verb "uskoa," which means "to believe." The conditional mood in Finnish expresses a hypothetical or uncertain situation, often translated into English as "would believe" or "would have believed."

Therefore, "uskoisivat" specifically refers to a group of people (they) who would believe or would have believed something under certain conditions. For instance, in a sentence like "Jos he olisivat kuulleet totuuden, he uskoisivat sen" (If they had heard the truth, they would believe it), "uskoisivat" indicates the hypothetical belief that would have occurred. The verb conjugation in Finnish is highly regular for the conditional mood, with the suffix "-isi-" being a key indicator, followed by the personal ending "-vat" for the third-person plural. This grammatical form is crucial for conveying nuanced meanings related to possibility, conjecture, and conditionality within the Finnish language.
