että

että is a Finnish subordinating conjunction used to introduce a dependent clause that expresses the content of a statement, thought, belief, or perception. It functions similarly to the English “that” in reporting speech or thought.

Common contexts include verbs of saying, thinking, knowing, or perceiving, as well as adjectives that express evaluation or certainty. Examples: Uskon, että hän tulee. Hän sanoi, että hän on valmis. On ilmeistä, että sää muuttuu. Olen varma siitä, että se oli oikea ratkaisu. En usko, että hän tulee. These clauses share a finite verb form in the subordinate clause, usually in indicative mood, though conditional forms can appear in explicit hypothetical contexts.

In Finnish punctuation, a comma typically precedes that-clause introduced by että: Olin varma siitä, että se meni oikein. That-clauses can be embedded in longer sentences and may themselves contain other that-clauses, creating multiple layers of reporting or belief.

Relation to other conjunctions: että contrasts with jotta, which introduces a purpose or goal clause (for example, jotta hän voisi tulla). That-clauses can be used after many different verbs and adjectives, making that-constructions a central feature of Finnish reported content rather than reference to future plans or purposes.

Overall, että serves as a key tool for conveying reported content, opinion, or perception in neutral, declarative statements.
