Sprettekniven ligger på bordet.

Because Norwegian normally writes compound nouns as a single word.

So sprettekniven is built from:

• sprette-
• kniv = knife

The main noun is kniv, and the first part describes what kind of knife it is.

This is very common in Norwegian:

• fotball = football
• sommerferie = summer holiday
• kjøkkenbord = kitchen table

English often writes similar ideas as two words, but Norwegian usually joins them.

The ending -en marks the noun as definite singular for a masculine noun.

So:

• en sprettekniv = a switchblade / a flick knife
• sprettekniven = the switchblade / the flick knife

In Norwegian, the idea of the is usually added to the end of the noun instead of being a separate word.

Because bord is a neuter noun, and the definite singular ending for many neuter nouns is -et.

So:

• et bord = a table
• bordet = the table

This is parallel to:

• et hus → huset
• et eple → eplet

So the sentence uses two definite nouns:

• sprettekniven = the knife
• bordet = the table

Because Norwegian usually expresses definiteness with a suffix attached to the noun.

Compare English and Norwegian:

• English: the knife

• Norwegian: kniven

• English: the table
• Norwegian: bordet

So in Sprettekniven ligger på bordet, both the ideas are already built into the nouns.

Norwegian often uses a position verb where English would simply use is.

Here, ligger means lies / is lying and is used for something that is resting horizontally or lying somewhere.

So:

• Sprettekniven ligger på bordet = The switchblade is lying on the table

This sounds more natural in Norwegian than using er.

Norwegian often distinguishes between different positions:

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

For example:

• Boka ligger på bordet = The book is lying on the table
• Flaska står på bordet = The bottle is standing on the table
• Katten sitter på stolen = The cat is sitting on the chair

Ligger is the present tense of the verb ligge.

So:

• infinitive: å ligge = to lie
• present: ligger = lies / is lying
• past: lå
• past participle: ligget

In this sentence, ligger describes the knife’s current location.

Also, Norwegian verbs do not change according to person:

• jeg ligger
• du ligger
• han ligger
• vi ligger

That is simpler than English in some ways.

På means on here, and it is the normal preposition for something resting on the surface of a table.

So:

• på bordet = on the table

This is the natural choice because the knife is located on top of the table.

If you used a different preposition, the meaning would change:

• i bordet = in the table
• under bordet = under the table
• ved bordet = by the table / at the table

Yes. The normal word order here is:

• subject: Sprettekniven
• verb: ligger
• place expression: på bordet

So the sentence pattern is: Subject + Verb + Place

This is a standard Norwegian main-clause pattern.

You can also move the place expression to the front:

• På bordet ligger sprettekniven.

That is still correct, and the verb stays in second position. This is part of the V2 rule in Norwegian main clauses.

The dictionary forms are:

• sprettekniv = switchblade / flick knife
• ligge = to lie
• bord = table

The sentence uses inflected forms:

• sprettekniven = definite singular
• ligger = present tense
• bordet = definite singular

Looking up dictionary forms is very useful when learning Norwegian, because the form in the sentence is often not the basic form.

In Norwegian, nouns are not capitalized the way they are in German.

So:

• sprettekniven
• bordet

are written with lowercase letters unless they begin the sentence.

Here, Sprettekniven has a capital S only because it is the first word of the sentence.

You would use the indefinite forms:

• En sprettekniv ligger på et bord.

That means A switchblade is lying on a table.

Compare:

• en sprettekniv = a switchblade

• sprettekniven = the switchblade

• et bord = a table
• bordet = the table

So the original sentence is definite, while this version is indefinite.
