Finnish
Etymology
From the pronominal stem jo- + the suffix -ka/kä.
Relative pronoun
joka (stem jo-, see below)
- who, which, that.
Declension
The suffix -ka is retained when the case suffix doesn't add a syllable. Eg. the genitive singular is jonka but the inessive plural is joissa.
Indefinite pronoun
joka (indeclinable)
- every, each.
