Numbers One to Four
The numbers 1-4 match the noun's gender: tveir menn (two men), tvær konur (two women), tvö börn (two children).
How It Works
The forms.
- 1: einn (masculine), ein (feminine), eitt (neuter)
- 2: tveir, tvær, tvö
- 3: þrír, þrjár, þrjú
- 4: fjórir, fjórar, fjögur
Examples. einn maður (one man), ein kona (one woman), eitt barn (one child); þrír menn, þrjár konur, þrjú börn.
Counting. When you count without a noun, use the masculine: einn, tveir, þrír, fjórir, fimm. Telling the time uses the neuter: klukkan eitt, tvö, þrjú, fjögur; see klukkan.
Mixed groups. For a group of men and women, use the neuter: Við erum fjögur (There are four of us).
Case. These numbers also change with case, like adjectives. As an object, masculine tveir, þrír and fjórir become tvo, þrjá and fjóra: Ég á tvo bræður (I have two brothers). Feminine ein becomes eina, but the other feminine and neuter forms stay the same as objects. See numbers 1-4 in all cases.
Not an article. einn means "one", not "a". Icelandic has no word for "a": Ég á bíl (I have a car).

systir is feminine, so two is tvær.

barn is neuter, so three is þrjú.

Common Mistakes
Using the masculine form with a feminine noun.
Tveir konur búa hér.Tvær konur búa hér.kona is feminine, so two is tvær. Check the gender of the noun before you choose the number.
Using the neuter form with a masculine noun.
Það eru þrjú menn hér.Það eru þrír menn hér.maður is masculine, so three is þrír. þrjú is only for neuter nouns such as börn.
Keeping tveir as an object.
Ég á tveir bræður.Ég á tvo bræður.bræður is the object of á, so the masculine number changes to its accusative form tvo.
