Who (Kuka)

Level 1

Kuka is the Finnish word for 'who'. It is used to ask about the identity of a person. Unlike English, it changes its form (declines) depending on its role in the sentence.

How It Works

In Finnish, kuka is used exclusively for people. It functions as an interrogative pronoun and must match the case required by the verb or context.

1. The Paradigm (Declension)
The word is 'suppletive', meaning it uses different roots for different cases:

  • Nominative: kuka (Who - singular)
  • Nominative Plural: ketkä (Who - plural)
  • Genitive: kenen (Whose)
  • Partitive: ketä (Whom - used with partitive verbs)
  • Accusative: kenet (Whom - for total objects)
  • Adessive: kenellä (Who has / On whom)
  • Allative: kenelle (To whom)

2. Kuka vs. Mikä
Use kuka for identity (names). Use mikä for things, or when asking about a person's profession or role (e.g., Mikä hän on? - 'What is he?' meaning 'What is his job?').

3. Names are 'Things'
A common trap for English speakers is asking 'Who is your name?'. In Finnish, a name is a thing, so you must use Mikä sinun nimesi on?

4. Spoken Language Note
In some western dialects (like Pori or Turku), you might hear ketä used instead of kuka in the basic form (e.g., Ketä se on?). This is non-standard but very common in those regions.

  1. Kuka sinä olet?

    Who are you?

    Word by Word: Who you are?

    The basic nominative form used to ask for someone's identity.

  2. Kenen tämä kirja on?

    Whose book is this?

    Word by Word: Whose this book is?

    The genitive form 'kenen' is used to show possession.

  3. Ketä sinä rakastat?

    Whom do you love?

    Word by Word: Whom you love?

    The partitive form 'ketä' is required because 'rakastaa' is a partitive verb.

  4. Kenelle sinä soitat?

    To whom are you calling?

    Word by Word: To-whom you call?

    The allative case (-lle) is used to indicate the recipient of the call.

  5. Ketkä tulevat juhliin?

    Who (plural) are coming to the party?

    Word by Word: Who-plural come to-party?

    The plural form 'ketkä' is used when you expect the answer to be multiple people.

Common Mistakes

  • Using 'kuka' to ask for a name.

    Kuka sinun nimesi on?
    Mikä sinun nimesi on?

    In Finnish, names are considered 'things', so you must use 'mikä' (what) instead of 'kuka' (who).

  • Trying to decline 'kuka' using the 'ku-' stem.

    Kukan kirja tämä on?
    Kenen kirja tämä on?

    The pronoun is irregular. You cannot say 'kukan'; you must switch to the stem 'kene-' for the genitive form.

  • Using 'kuka' as a relative pronoun to link sentences.

    Mies, kuka asuu täällä.
    Mies, joka asuu täällä.

    Kuka is only for questions. To say 'The man WHO lives here', you must use the relative pronoun 'joka'.
