It and they: den, det, de, dem

Swedish has two words for 'it'. Choose by the gender of the noun you are replacing:

• en noun → den: Jag har en ny jacka. Den är blå. (It is blue.)
• ett noun → det: Jag har ett nytt bord. Det är vitt. (It is white.)

Den and det stay the same as subject and object: Jag hittar inte den. (I can't find it.)

For 'they' and 'them' there are two forms:

• de is the subject: De bor i Luleå. (They live in Luleå.)
• dem is the object or follows a preposition: Jag ser dem. (I see them.)

In speech both de and dem sound like 'dom'. Tip: if English would say 'they', write de; if it would say 'them', write dem.
