Relative Pronoun: joka, jonka, jossa

The relative pronoun joka (who, which, that) opens a clause after a comma. It takes the number of the noun it refers to, but its case comes from its role in its own clause.

• subject: joka, plural jotka
• total object: jonka (Mies, jonka näin), plural jotka
• partitive object: jota (Kirja, jota luen), plural joita
• genitive before kanssa, luona or a noun: jonka, plural joiden
• in, from, to: jossa, josta, johon (for places also jonne), plural joissa
• jolla (with which; who has), jolta (from whom), jolle (to whom)

Ask what the verb inside the clause needs: asua → jossa, puhua → josta, antaa → jolle, odottaa → jota, luottaa → johon.
