Counting from One to Four
In Icelandic, the numbers 1 through 4 change their form depending on the gender of the noun they describe. When counting out loud or talking about masculine nouns, you will use their default masculine forms: einn (1), tveir (2), þrír (3), and fjórir (4).
When you use these numbers in a sentence, place them directly before the noun. Remember that any number greater than one requires a plural noun and a plural verb (like eru, meaning "are").
| Here is one car. | Hér er einn bíll. |
| Here are two cars. | Hér eru tveir bílar. |
| We are three friends. | Við erum þrír vinir. |
| Four men come home now. | Fjórir menn koma heim núna. |
Numbers Five to Ten
The numbers 5 through 10 are uninflected, which means they never change their form, no matter the gender of the noun. You can use them with masculine nouns, neuter nouns (like börn), or feminine nouns (like konur) without altering the number.
These numbers are fimm (5), sex (6), sjö (7), átta (8), níu (9), and tíu (10).
| Five boys sleep inside. | Fimm strákar sofa inni. |
| Where are six doctors? | Hvar eru sex læknar? |
| Seven students study at home. | Sjö nemendur læra heima. |
| Here are eight children. | Hér eru átta börn. |
| Nine women talk together outside. | Níu konur tala saman úti. |
| We are ten. | Við erum tíu. |
