Svarfristen er i morgen.

It is a compound noun, which is very common in Norwegian:

• svar = answer, reply
• frist = deadline, time limit
• -en = the definite ending

So svarfristen is literally the answer-deadline or the reply deadline.

Norwegian often joins words together where English would use separate words.

In Norwegian, the definite article is often added to the end of the noun instead of being a separate word before it.

Here:

• frist = a deadline
• fristen = the deadline

Because svarfrist is a compound noun, the definite ending goes on the whole word:

• svarfrist = reply deadline
• svarfristen = the reply deadline

So English uses a separate word, but Norwegian often uses a suffix.

Er is the present tense of å være = to be.

This sentence is simply stating a fact about the deadline:

• Svarfristen er i morgen

Norwegian usually needs an explicit verb in this kind of sentence, just like English does. You cannot normally leave it out.

In modern standard Norwegian, i morgen is normally written as two words.

It is a fixed time expression meaning tomorrow.

This is something learners just need to get used to, because it does not follow the same pattern as English spelling. Even though English has one word, Norwegian usually writes it as two.

Not in this sentence.

Although morgen is related to morning, the expression i morgen usually means tomorrow.

Compare:

• i morgen = tomorrow
• i morges = this morning
• om morgenen = in the morning, in the mornings

So here, i morgen is a time expression for the next day, not for the morning part of the day.

Because i morgen is a fixed idiomatic expression in Norwegian.

You generally say:

• i dag = today
• i morgen = tomorrow
• i går = yesterday

So even if English does not use a preposition here, Norwegian does. It is best to learn i morgen as one complete chunk.

Yes, absolutely.

Both are correct, but they emphasize slightly different things:

• Svarfristen er i morgen = focuses first on the deadline
• I morgen er svarfristen = puts the time first, like Tomorrow is the deadline

This is a good example of Norwegian V2 word order: when you move i morgen to the front, the verb er still stays in second position.

A useful rough guide is:

SVAR-fris-ten

Things to notice:

• The main stress is usually on the first part: SVAR
• The a in svar is pronounced like a broad a
• The r may sound different depending on the dialect
• fristen has a clear i sound, roughly like frees-ten in many accents

A very approximate English-style pronunciation guide would be:

SVAHR-frees-ten

But it is better to listen to native audio if you can, since Norwegian vowel sounds do not match English exactly.

This sentence is standard Bokmål.

In Nynorsk, you would more likely see:

• Svarfristen er i morgon

The main difference here is morgen in Bokmål versus morgon in Nynorsk.

So if you are studying Bokmål, Svarfristen er i morgen is exactly the form you should learn.
