Festivalpasset ligger i lommen min.

Because Norwegian usually writes compound nouns as one word.

So:

• festival
  • pass → festivalpass = festival pass
• then the definite ending is added:
  • festivalpasset = the festival pass

This is very normal in Norwegian. English often separates words where Norwegian combines them.

Examples:

• togstasjon = train station
• sommerferie = summer holiday
• festivalpass = festival pass

The ending -et is the definite article attached to the noun.

The base noun is:

• et pass = a pass

The definite form is:

• passet = the pass

Since festivalpass is built on pass, it follows the same neuter pattern:

• et festivalpass = a festival pass
• festivalpasset = the festival pass

So Norwegian often puts the at the end of the noun instead of using a separate word.

Because Norwegian often uses verbs like ligge, stå, and sitte to describe where something is, especially physical objects.

Here:

• ligger literally means lies / is lying

In this sentence, it means the festival pass is physically located in the pocket.

So:

• Festivalpasset ligger i lommen min. = The festival pass is in my pocket.

Using er is sometimes possible in Norwegian, but ligger sounds more natural for an object resting somewhere.

A useful idea:

• er = is, in a general sense
• ligger = is located somewhere, lying there

Ligger is the present tense of å ligge.

So:

• å ligge = to lie / to be lying
• ligger = lies / is lying

Norwegian verbs do not change for person the way English verbs sometimes do.

Examples:

• Jeg ligger = I am lying
• Du ligger = you are lying
• Festivalpasset ligger = the festival pass is lying

The verb form stays ligger.

Both are possible, but they are used a little differently.

Most common, everyday pattern:

• lommen min = my pocket

This structure is:

• noun in the definite form
• then the possessive

So:

• lommen = the pocket
• min = my
• lommen min = my pocket

Also possible:

• min lomme

This is more marked, more formal, or more contrastive in many contexts.

So in everyday Norwegian, i lommen min sounds very natural.

Because when the possessive comes after the noun, Norwegian normally uses the definite form of the noun.

Pattern:

• boken min = my book
• jakka di = your jacket
• huset vårt = our house

So:

• lomme = pocket
• lommen = the pocket
• lommen min = my pocket

This is a very common Norwegian structure.

Because Norwegian usually puts the definite article onto the end of the noun.

So instead of:

• the pocket

Norwegian says:

• lommen

The -en ending already means the.

That is why i lommen min does not need a separate word like English the.

Lomme is traditionally a feminine noun, but in Bokmål many feminine nouns can also be treated as masculine.

So you may see:

• ei lomme / lomma mi
• en lomme / lommen min

Both are possible in Bokmål.

In your sentence, the speaker is using the masculine/common-gender style:

• en lomme
• lommen min

If someone prefers more feminine forms, they might say:

• Festivalpasset ligger i lomma mi.

That means the same thing.

Yes, people would understand it, and it is not grammatically wrong. But ligger usually sounds more idiomatic when talking about an object physically resting somewhere.

Compare:

• Festivalpasset er i lommen min.
  More neutral: the pass is in my pocket.

• Festivalpasset ligger i lommen min.
  More natural for a physical object located there.

Norwegian often prefers these position/location verbs:

• ligge = lie
• stå = stand
• sitte = sit

Yes, but it is a very normal Norwegian sentence pattern.

The basic order here is:

• Festivalpasset = subject
• ligger = verb
• i lommen min = place phrase

So:

• Subject + Verb + Place

You can also move the place phrase to the front:

• I lommen min ligger festivalpasset.

That is also correct. When something other than the subject comes first in a Norwegian main clause, the verb still stays in second position. This is the usual V2 pattern.

A rough English-friendly guide would be:

• festivalpasset ≈ feh-stee-VAHL-pahs-set
• ligger ≈ LIG-er
• i ≈ ee
• lommen ≈ LOM-men
• min ≈ meen

A couple of useful notes:

• g in ligger is not pronounced like a hard English g.
• i is pronounced like ee.
• Norwegian pronunciation varies by dialect, so exact pronunciation can differ.

Word by word, it is roughly:

• Festivalpasset = the festival pass
• ligger = lies / is lying
• i = in
• lommen min = my pocket

So the literal sense is:

• The festival pass lies in my pocket.

That is why the natural English translation is simply:

• The festival pass is in my pocket.
