Partitive constructions (en av…)

When you want to talk about a specific portion of a larger, defined group—such as "one of you" or "many of the cards"—Swedish uses a partitive construction.

This is formed simply by taking a quantity word, adding av (of), and following it with either an object pronoun (like oss, er, dem) or a definite plural noun.

One of you must cut the deck before the card game begins.
En av er måste kupera kortleken innan kortspelet börjar.
That card game requires that one takes many of the tricks.
Det där kortspelet kräver att man tar många av sticken.

Card Suits in the Definite

When discussing a game of cards (kortspelet), you will frequently refer to the four suits: spader (spades), hjärter (hearts), klöver (clubs), and ruter (diamonds). When talking about a specific suit played in a trick, Swedish treats them as singular en-words in their definite forms: spadern, hjärtern, klövern, and rutern.

You can seamlessly combine these with other partitive expressions, like ingen av (none of).

Does none of you have the spade or the heart?
Har ingen av er spadern eller hjärtern?

Matching Gender: En av vs. Ett av

When saying "one of," remember that the word for "one" must match the gender of the noun you are extracting it from. Use en av for en-words (and people), and ett av for ett-words.

In a deck of cards, a jack (en knekt) is an en-word, but an ace (ett ess) is an ett-word. Notice how both nouns take their definite plural forms in this construction:

One of the aces and one of the jacks are missing.
Ett av essen och en av knektarna saknas.

Other Quantity Words

You can build this construction with almost any quantity word. This includes numbers (två av), question words (vilket av), or indefinite pronouns like några av (some of).

Some of the jokers are still lying in the box.
Några av jokrarna ligger kvar i lådan.
Which of the aces is most complicated to play?
Vilket av essen är mest komplicerat att spela?
One of them takes the trick with the diamond.
En av dem tar sticket med rutern.
