Questions & Answers about Kniven er skarp.

What does the -en at the end of Kniven mean?

It’s the definite singular ending for a common-gender noun. Kniv = knife; kniven = the knife. In Bokmål, most masculine and feminine nouns form the definite singular with -en (or -a for many feminine nouns).

• Indefinite singular: en kniv (a knife)
• Definite singular: kniven (the knife)
• Indefinite plural: kniver (knives)
• Definite plural: knivene (the knives)

Why is there no separate word for “the” in Kniven er skarp?

Norwegian normally uses a suffix on the noun for definiteness instead of a separate word: kniv → kniven. A separate article appears in “double definiteness” when an adjective comes before the noun: den skarpe kniven (the sharp knife). So:

• Predicate after the noun: Kniven er skarp.
• Attributive before the noun: den skarpe kniven

Could I say Kniv er skarp?

Not for normal speech. For general statements, Norwegian uses either:

• Indefinite singular generic: En kniv er skarp. (A knife is sharp = knives in general are sharp.)
• Plural generic: Kniver er skarpe. (Knives are sharp.) Using a bare singular without article (Kniv er skarp) is unidiomatic in Bokmål.

How do I form the question “Is the knife sharp?” and the negative?

• Yes/no question: Er kniven skarp?
• Negative statement: Kniven er ikke skarp.
• Negative question: Er ikke kniven skarp? (or more colloquially Er ikke kniven skarp, da? in some contexts)

How do I answer briefly “Yes, it is” or “No, it isn’t”?

• Yes: Ja, den er det. or simply Ja, den er skarp.
• No: Nei, det er den ikke. or Nei, den er ikke skarp. Use den because kniv(en) is common gender. The little det in “det er den” is a common confirmation pattern.

Why is the adjective skarp not skarpe here?

After the verb er (a predicate adjective), the endings are:

• Singular common gender: no ending → skarp (Kniven er skarp.)
• Singular neuter: -t → skarpt (Sverdet er skarpt. “The sword is sharp.”)
• Plural (all genders): -e → skarpe (Knivene er skarpe. “The knives are sharp.”)

Before a definite noun (attributive), you also use -e: den skarpe kniven.

How would this change with a neuter noun or with plurals?

• Neuter singular: Sverdet er skarpt. (the sword; sverd is neuter)
• Common-gender singular: Kniven er skarp.
• Plural: Knivene er skarpe. / Sverdene er skarpe.

What’s the verb er here?

Er is the present tense of å være (to be). Basic forms:

• Present: er (is/are)
• Preterite (was/were): var → Kniven var skarp.
• Present perfect (has been): har vært → Kniven har vært skarp.
• Future (will be): skal være → Kniven skal være skarp.

How do I intensify or soften the statement?

• Intensify: Kniven er veldig/svært skarp.; colloquial prefix: kjempe- → Kniven er kjempeskarp.
• Soften: Kniven er ganske/litt/temmelig skarp.
• “Not very”: Kniven er ikke særlig skarp.

What’s the difference between skarp, spiss, and sløv?

• skarp = sharp (able to cut; also figuratively: a sharp remark, sharp vision)
• spiss = pointy/pointed (shape of a point rather than cutting edge)
• sløv = dull/blunt (not sharp) Examples:
• Kniven er skarp. (cuts well)
• Kniven er spiss. (has a pointed tip)
• Kniven er sløv. (needs sharpening)

How do I say “the sharp knife” versus “the knife is sharp”?

• Attributive (before noun, double definiteness): den skarpe kniven
• Predicative (after verb): Kniven er skarp.

How is the pronunciation?

Approximate Standard East Norwegian:

• Kniven: [ˈkniːvən] — the initial k is pronounced (unlike English “knife”); long i.
• er: [ær] or [eːɾ] depending on dialect; a short “air/ehr” sound with a tapped/flapped r.
• skarp: [skɑrp] — sk is [sk] here (before a it stays [sk]); a like “father”; tapped r; clear p.

Tip: sk becomes a “sh” sound [ʃ] before front vowels like i/y/e/ei/øy (e.g., skinke “ham”), but not in skarp (before a).

Is this the same in Bokmål and Nynorsk?

Yes, Kniven er skarp. is fine in both. Inflection patterns and agreement rules shown here apply across the standards, though Nynorsk has some vocabulary preferences elsewhere.

Can I use a demonstrative like “that knife”?

Yes:

• Den kniven er skarp. = That (particular) knife is sharp. With an adjective, still use double definiteness:
• Den skarpe kniven er ny. = That sharp knife is new.

Where do adverbs go?

They typically follow the verb er:

• Kniven er fortsatt skarp.
• Kniven er veldig skarp. With ikke (not): Kniven er ikke skarp.

Any quick mini-paradigm for the adjective skarp?

• Positive: skarp
• Comparative: skarpere → Kniven er skarpere nå.
• Superlative (predicative): skarpest → Denne kniven er skarpest.
• Superlative (attributive): den skarpeste kniven → “the sharpest knife”

• Postposed possessive (neutral tone): Kniven min er skarp.
• Preposed possessive (more emphasis/contrast): Min kniv er skarp.
