Learn Danish: Fuglen flyver over huset. - The bird flies over the house.

In Danish, the word for 'the' attaches to the end of the noun. Which ending you use depends on the noun's gender. Fugl (bird) is an en-word (common gender), so it becomes fuglen. Hus (house) is an et-word (neuter gender), so it becomes huset.

How would I say 'The bird is flying over the house'?

You would use the exact same sentence: Fuglen flyver over huset. Danish does not have a separate 'is doing' (present continuous) form like English does. The present tense flyver translates to both 'flies' and 'is flying'.

Why does the verb flyver end in -r?

Adding an -r (or -er) is the standard way to form the present tense of Danish verbs. Unlike English, Danish verbs do not change based on who or what is doing the action. The dictionary form here is flyve (to fly), so adding -r makes it flyver for any subject.

Is the word over used the same way as it is in English?

Yes! Over is a cognate (a word with the same origin) to the English word 'over'. It is used in much the same way in Danish to describe position or movement above something.
