Usage notesEdit

  • In colloquial Finnish, the forms of jokin (used to refer to non-human things in the standard language) and joku (used to refer to humans in the standard language) have merged, especially when used as modifiers (for example joku mies / joku pöytä (some man / some table), joku meistä / joku niistä pöydistä (one of us / one of the tables). In referring to both humans and non-human things, joku is used as a modifier in everyday speech and writing in the nominative singular (joku) and genitive singular (jonkun) and the nominative and accusative plural (jotkut), but the forms of jokin are used in all other grammatical cases to refer to both humans and non-human things. When used alone, not as modifiers, the forms of joku and jokin are however usually still disinguished in everyday speech and writing in the nominative and partitive singular and plural and the genitive singular.[1][2] This is shown by the following examples of colloquial usage:
    joku mies tuli / antoi sen jollekin miehelle
    some man came / gave it to some man
    joku tuli / antoi sen jollekin
    someone came / gave it to someone
    joku pöytä meni rikki / laita se jollekin pöydälle
    some table broke / put it on some table
    jokin meni rikki / laita se jollekin
    something broke / put it on something
    and the following examples of formal (standard language) usage:
    joku mies / jollekulle miehelle
    some man came / to some man
    jokin pöytä / jollekin pöydälle
    some table / onto some table


  • Case suffixes are regular. Both the parts get the case suffix. Some cases are practically never used (those forms are in brackets in the table). The lative and causative cases are used as adverbs with completely different meanings than "some" or "someone".
