Banken kontrollerer statusen.

Because in Norwegian, the definite article the is usually added to the end of the noun instead of being a separate word.

• bank = bank
• banken = the bank
• status = status
• statusen = the status

So Banken kontrollerer statusen literally matches The bank checks the status.

That is a normal feature of Norwegian nouns. In many cases, definiteness is shown with an ending:

• en bank = a bank

• banken = the bank

• en status = a status
• statusen = the status

So where English uses a separate word (the), Norwegian often uses a suffix.

Kontrollerer usually means checks, verifies, or examines in a sentence like this.

Even though it looks like English controls, it often does not mean has power over in everyday usage. In this sentence, the most natural meaning is probably:

• checks the status
• verifies the status

So this is a good word to treat carefully, because it can look familiar but is not always used exactly like English control.

It is the present tense form of the verb å kontrollere (to check / to control / to inspect).

Examples:

• Jeg kontrollerer = I check
• Du kontrollerer = You check
• Banken kontrollerer = The bank checks

A useful point for learners: in Norwegian, the present tense verb form is the same for all subjects. You do not change it like English I check / she checks.

Yes, in this sentence it is the standard subject–verb–object order:

• Banken = subject
• kontrollerer = verb
• statusen = object

So:

• Banken kontrollerer statusen.
• The bank checks the status.

This is one reason the sentence feels fairly straightforward to an English speaker.

Yes, very often you could. Sjekker is a very common everyday verb meaning checks.

Compare:

• Banken kontrollerer statusen = a bit more formal, official, or technical
• Banken sjekker statusen = more everyday and conversational

Both can be correct, but kontrollerer may sound a little more formal or bureaucratic.

Yes, it matters because gender affects the noun endings.

In Bokmål:

• bank is usually common gender: en bank → banken
• status is also usually treated as common gender: en status → statusen

That is why both definite forms end in -en here.

Because the sentence refers to a specific status, not just the general idea of status.

Compare:

• Banken kontrollerer status. = The bank checks status / checks status information
  This sounds less specific and is less natural in many situations.
• Banken kontrollerer statusen. = The bank checks the status.
  This refers to a particular status.

So statusen is the natural choice when a specific status is meant.

A rough English-friendly guide would be:

• Banken ≈ BAHN-ken
• kontrollerer ≈ kon-tro-LEH-rer
• statusen ≈ sta-TOO-sen

A few pronunciation notes:

• Norwegian r is different from English r
• The o in kontrollerer is not exactly like English oh
• Stress is typically on:
  • BAN-ken
  • kontrolLErer
  • staTUsen

Exact pronunciation varies by dialect, but this is a helpful starting point.

You would change the verb:

• Banken kontrollerer statusen. = The bank checks the status.
• Banken kontrollerte statusen. = The bank checked the status.

The nouns stay the same here; only the verb changes from present to past.

No, not in a normal sentence like this. Norwegian usually requires an explicit subject.

So you say:

• Banken kontrollerer statusen.

You would not normally just say:

• Kontrollerer statusen.

That would sound incomplete unless it appeared in a very special context, such as notes, headings, or instructions.
