vilket

Vilket is a Swedish word that functions as an interrogative determiner and pronoun, meaning “which” or “what kind of.” It is used to ask about a specific item or choice among a set and agrees with the noun it modifies in gender and number.

Forms and usage: The form depends on gender and number of the noun. Vilket is the neuter singular form (ett-words), while Vilken is the common gender singular form (en-words), and Vilka is the plural form for all genders. Examples: Vilket hus vill du köpa? (Which house do you want to buy?) Vilken bok vill du läsa? (Which book do you want to read?) Vilka filmer såg du igår? (Which films did you watch yesterday?) Vilket av alternativen är bäst? (Which of the alternatives is best?)

Role in sentences: As a determiner, it precedes a noun: Vilket år var det? Vilket jobb vill du ha? As a pronoun, it can stand in place of a noun, especially in questions: Jag vet inte vilket. In relative clauses, which is more commonly expressed with som: Boken som jag köpte igår var bra, but in formal or older style you may encounter ett settningar där vilket refers to a neuter antecedent or to a whole clause, though this is less common in everyday Swedish.

Etymology and relations: Vilket belongs to a family of interrogative and demonstrative words in Swedish that include vilken, vilket and vilka, all tracing back to Germanic roots for “which.” It shares cognates with Norwegian and Danish equivalents such as hvilket.
