Prislappen mangler.

Prislappen means the price tag.

It is written as one word because Norwegian often forms compound nouns where English uses two separate words. Here:

• pris = price
• lapp = slip, label, tag

So prislapp is price tag, and prislappen is the price tag.

Because prislappen is the definite form, meaning the price tag.

• en prislapp = a price tag
• prislappen = the price tag

In Norwegian, the definite article is usually attached to the end of the noun instead of appearing as a separate word before it.

So:

• en bok = a book
• boken = the book

The same pattern is used here:

• en prislapp = a price tag
• prislappen = the price tag

Here, mangler means is missing.

The verb is å mangle, which can mean things like:

• to be missing
• to lack

In this sentence, Prislappen mangler means that the price tag is not there.

So a very natural English translation is:

• The price tag is missing

Because Norwegian uses mangler as the main verb, and that verb already carries the meaning that English expresses with is missing.

English uses:

• The price tag is missing

Norwegian uses:

• Prislappen mangler

So Norwegian does not need a separate er here.

If you said Prislappen er mangler, that would be wrong.

Yes. Å mangle can be used in more than one way.

For example:

• Prislappen mangler. = The price tag is missing.
• Skjorten mangler en knapp. = The shirt is missing a button.
• Jeg mangler penger. = I lack money.

So the verb can describe either:

• something that is absent
• someone or something that does not have enough of something

The word order is the normal Norwegian statement order:

• subject + verb

Here:

• Prislappen = subject
• mangler = verb

So it is a very straightforward sentence structure.

If you turned it into a yes/no question, the verb would come first:

• Mangler prislappen? = Is the price tag missing?

The dictionary forms are:

• en prislapp = a price tag
• å mangle = to be missing / to lack

In the sentence, they appear as:

• prislappen = definite singular form of en prislapp
• mangler = present tense of å mangle

So the sentence is built from a noun in the definite singular and a verb in the present tense.

A simple learner-friendly approximation is:

PREES-lap-pen MANG-ler

A few helpful notes:

• pris sounds roughly like prees
• lapp has a short vowel and a clear p
• -en at the end is the definite ending
• mangler has the main stress on the first syllable: MANG-ler

The exact pronunciation depends a bit on accent and dialect, but that approximation is good enough for a learner to start with.
