Konserten er i september.

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

• konsert = concert
• konserten = the concert

So konserten already includes the meaning of the concert. That is why you do not say den konserten here unless you mean something more like that concert or you are using a special structure.

The dictionary form is konsert.

You would usually learn it as:

• en konsert = a concert
• konserten = the concert

So the sentence uses the definite singular form of the noun.

Er is the present tense of å være, which means to be.

So:

• å være = to be
• er = is / am / are

In this sentence, er means is:

• Konserten er i september. = The concert is in September.

Norwegian normally uses i with months, seasons, years, and many time periods.

So:

• i september = in September
• i april = in April
• i 2026 = in 2026
• i vinter = in winter

This is very similar to English, where we also say in September.

In Norwegian, names of months are normally written with a lowercase letter, unlike in English.

So Norwegian writes:

• september
• oktober
• januar

But English writes:

• September
• October
• January

So Konserten er i september. is correctly written in Norwegian.

Yes. The normal word order here is:

• Konserten = subject
• er = verb
• i september = time expression

So the pattern is basically subject + verb + time expression.

This is the standard order in a simple statement. Norwegian usually keeps the finite verb in the second position, so if you move something else to the front, the verb still comes second:

• I september er konserten.

That version is grammatically possible, but it sounds more marked or contrastive. The original sentence is the most neutral and natural version.

No. En konserten is not correct.

That is because Norwegian does not normally use both the indefinite article and the definite ending together.

Use:

• en konsert = a concert
• konserten = the concert

So you choose one form or the other depending on whether the noun is indefinite or definite.

A rough English-friendly pronunciation would be something like:

kon-SERR-ten er ee sep-TEM-ber

A few notes:

• konserten has the definite ending -en
• er is often pronounced quite lightly in normal speech
• september is usually stressed around TEM

The exact pronunciation depends somewhat on dialect, but this rough version is good enough for a learner to recognize and begin saying it.

Yes. Because it is in the definite form, konserten usually refers to a specific concert that both speaker and listener can identify from the context.

So this sentence is not talking about concerts in general. It means a particular concert is happening in September.

Compare:

• En konsert er i september. = A concert is in September.
  This sounds odd without more context.
• Konserten er i september. = The concert is in September.
  This refers to a specific concert.

Yes. I september places the concert in the month of September, but it does not specify the exact day.

So it could mean:

• the concert happens at some point in September
• the speaker is only giving the month, not the full date

If you wanted to be more specific, you could add a date, for example:

• Konserten er 12. september. = The concert is on September 12th.
