Questions & Answers about Vi øver ental og flertal, fordi de samme navneord ofte ser forskellige ud.

Why is it Vi øver and not something like Vi øver os?

In Danish, øve can be used transitively, which means it can take a direct object:

• Vi øver ental og flertal = We practice singular and plural.

You can also meet øve sig or øve sig på, but that is used in other patterns, for example when talking about training yourself or practicing at something in a broader sense.

So in this sentence, øver is simply taking the thing being practiced as its object.

Why is there no article before ental og flertal?

Because ental and flertal are being used as general grammar concepts, not as specific countable items.

Danish often leaves out the article with abstract or category words when speaking generally:

• Vi øver ental og flertal = We practice singular and plural.
• compare English: We study grammar, not usually the grammar in a general statement.

If you were talking about a specific singular form or plural form in context, an article might appear, but here it is a broad statement.

What exactly is fordi doing here?

Fordi means because and introduces a reason:

• Vi øver ental og flertal = main idea
• fordi ... = reason for it

So the structure is:

• We practice singular and plural
• because the same nouns often look different

It is a very common conjunction in Danish.
