Skredderen åpner systuen snart.

Because Norwegian usually marks the by adding it to the end of the noun.

• skredder = tailor
• skredderen = the tailor
• systue = sewing room / sewing workshop / tailor’s shop
• systuen = the sewing room / the workshop / the shop

So instead of a separate word like English the, Norwegian often uses a definite ending.

A useful extra point: if there is an adjective, Norwegian often uses both a separate article and the definite ending, for example den nye systuen = the new sewing workshop.

That is very common in Norwegian. The present tense is often used for the near future when a time word makes the meaning clear.

So:

• Skredderen åpner systuen snart.
  = The tailor opens the shop soon / is opening the shop soon / will open the shop soon.

The word snart tells you this is about something that has not happened yet.

English also sometimes does this, but Norwegian uses it very naturally.

The infinitive is å åpne, which means to open.

Here are the forms:

• å åpne = to open
• åpner = opens / is opening
• åpnet = opened / has opened (depending on context)

In this sentence, åpner is the present tense form.

Literally, systue means something like sewing room. But in real usage, it can refer to:

• a sewing workshop
• a dressmaker’s workroom
• a small tailor’s shop
• a place where clothes are made or altered

So in this sentence, systuen probably means the tailor’s workshop/shop, not just an ordinary room in a house.

Yes, possibly.

Stue is traditionally a feminine noun, and in Bokmål many feminine nouns can appear in two styles:

• systuen
• systua

Both can be acceptable, depending on the speaker’s style and the variety of Bokmål being used.

Very roughly:

• -en often feels more neutral or conservative in Bokmål
• -a often feels more clearly feminine and can sound more colloquial or more natural for some speakers

So systuen is perfectly fine, but systua may also be possible.

Because that is a very natural place for it in a simple statement.

The sentence follows a common pattern:

• Skredderen = subject
• åpner = verb
• systuen = object
• snart = time adverb

So the structure is:

subject + verb + object + time word

That gives:

Skredderen åpner systuen snart.

You can also move snart to the front for emphasis:

Snart åpner skredderen systuen.

But then Norwegian word order changes, and the verb must still stay in the second position.

Yes. Norwegian is a V2 language, which means the finite verb usually comes in the second position in main clauses.

In the original sentence:

Skredderen | åpner | systuen | snart

If you move snart to the front, the verb still stays second:

• Snart åpner skredderen systuen.

You would not normally say:

• Snart skredderen åpner systuen. ❌

So this sentence is a good example of normal Norwegian main-clause word order.

It can mean either, depending on context.

With systuen, the most natural meaning is probably:

• opening the workshop/shop for business
• starting operations
• opening to customers

It could also literally mean opening up the room, but most learners would understand this sentence as talking about the tailor opening the sewing shop/workroom in a business sense.

Yes. That is also correct, but it gives a slightly different feel.

• Skredderen åpner systuen snart.
  = a neutral future meaning; often sounds like a plan, schedule, or expected event

• Skredderen skal åpne systuen snart.
  = more clearly is going to open / plans to open

So both work, but skal makes the future intention more explicit.

The letter å is a separate Norwegian vowel. It is pronounced somewhat like the vowel in English more or saw for many speakers, though it is not exactly the same.

So åpner starts with a sound roughly like:

• OH-...

A rough learner-friendly pronunciation could be:

• OH-pner

The exact Norwegian sound is best learned by listening, but the main thing is that å is not pronounced like English a in apple or name.

Because in Norwegian, the noun itself often carries the meaning of the.

So:

• skredder = a tailor / tailor
• skredderen = the tailor

That is the normal pattern in Norwegian. English speakers often expect a separate article, but in Norwegian the definite form is usually built into the noun.

So Skredderen åpner systuen snart is already complete. You do not add another word for the before skredderen or systuen here.
