Jeg vet ikke om teposene er i skuffen, men det ser ut til at du fant dem.

Here om means whether / if.

After verbs like vite (to know), Norwegian often uses om to introduce an indirect yes/no question:

• Jeg vet ikke om teposene er i skuffen.
• I don’t know whether the tea bags are in the drawer.

This is different from om meaning about in other sentences, such as:

• Vi snakker om været.
• We are talking about the weather.

So in this sentence, om does not mean about.

Teposene is the definite plural form of tepose (tea bag).

• en tepose = a tea bag
• teposen = the tea bag
• teposer = tea bags
• teposene = the tea bags

Since the sentence is talking about specific tea bags, Norwegian uses the definite plural -ene ending.

Skuffen means the drawer. Norwegian usually adds the definite article as an ending instead of using a separate word like the.

• en skuff = a drawer
• skuffen = the drawer

So i skuffen means in the drawer.

Because the tea bags are understood to be inside the drawer, Norwegian uses i (in).

• i skuffen = in the drawer
• på skuffen would mean on the drawer, which is a different idea

This is very similar to English.

Because after om, this is a subordinate clause (an indirect question), and subordinate clauses normally use normal statement word order in Norwegian:

• teposene er i skuffen

Compare:

• Direct question: Er teposene i skuffen?
• Indirect question: Jeg vet ikke om teposene er i skuffen.

So English and Norwegian behave similarly here: direct questions invert the verb and subject, but indirect questions usually do not.

In a main clause, Norwegian usually places ikke after the finite verb.

So:

• Jeg vet ikke ...

This is standard main-clause word order.

A useful comparison:

• Main clause: Jeg vet ikke
• Subordinate clause: ... fordi jeg ikke vet

In subordinate clauses, ikke usually comes before the finite verb. But in your sentence, Jeg vet ikke is the main clause, so ikke comes after vet.

Det ser ut til at is a common expression meaning it looks like / it seems that.

Literally, ser ut involves look out, but you should learn ser ut til at as a fixed expression.

So:

• det ser ut til at du fant dem
• it looks like / it seems that you found them

It is often used when the speaker is drawing a conclusion from what they can see or infer.

A close alternative is:

• Det virker som om du fant dem.
• It seems like you found them.

Here det is a dummy subject. It does not refer to a specific thing.

English does the same:

• It seems that ...
• It looks like ...

The it in those English sentences does not really refer to an object; it is just required by the sentence structure. Norwegian det works the same way here.

Fant is the past tense of finne (to find).

Forms of finne:

• å finne = to find
• finner = find / am finding
• fant = found
• har funnet = have found

So:

• du fant dem = you found them

If the sentence were in the present perfect, it would be:

• du har funnet dem = you have found them

Because dem is the object form of the pronoun, while de is the subject form in standard written Norwegian.

• De fant teposene. = They found the tea bags.
• Du fant dem. = You found them.

Here, the tea bags are receiving the action of finding, so Norwegian uses the object form dem.

Yes. Norwegian has several natural ways to express this idea.

Common options include:

• Det ser ut til at du fant dem.
• Det ser ut som at du fant dem.
• Det virker som om du fant dem.

They are all natural, though they can differ slightly in style or frequency depending on speaker and context. The version in your sentence is perfectly standard and idiomatic.

Yes, this is Bokmål.

Clues include forms like:

• jeg
• ikke
• teposene
• skuffen

In Nynorsk, some words would often be different, for example:

• eg instead of jeg
• ikkje instead of ikke

So this sentence is clearly standard Bokmål.
