Learn Icelandic: Þrír hundar sitja hér.

In Icelandic, the numbers 1, 2, 3, and 4 change their ending to match the gender of the noun they describe. Because hundar (dogs) is a masculine noun, we use the masculine form of three, which is þrír.

How did hundur (dog) become hundar?

To make a word plural, Icelandic changes its ending. Many masculine nouns that end in -ur in the singular drop that ending and add -ar to become plural.

Why is the verb sitja instead of situr?

Verbs change their shape depending on who is doing the action. Because there are three dogs, we need the plural form of the verb, which is sitja. If it were just one dog, we would use the singular form and say hundur situr.

Is the word order here exactly the same as in English?

Yes! In simple sentences stating what someone is doing and where, Icelandic uses the exact same Subject-Verb-Location order as English. The number also goes right before the noun it counts.
