Learn Hardcore Norwegian: Kniven er så skarp at jeg skjærer raskt på skjærebrettet. - The knife is so sharp that I cut quickly on the cutting board.

Den er så dyr at jeg venter. = “It’s so expensive that I’m waiting.”
Han snakker så fort at jeg ikke forstår. = “He speaks so fast that I don’t understand.”

Why is it at and not å?

at = the conjunction “that,” introducing a clause: … at jeg skjærer …
å = the infinitive marker “to,” used before a verb: å skjære = “to cut.”
Quick test: If you can replace it with “that,” use at; if with “to (do something),” use å.

Why is it raskt and not rask?

Raskt is the adverb form of the adjective rask. In Norwegian, many adjectives form adverbs by adding -t:

rask (fast, adj) → raskt (quickly, adv)
langsom (slow) → langsomt (slowly)
Some adverbs are irregular, e.g., god → godt, and some are invariable, e.g., fort (fast/quickly).

Could I use fort instead of raskt?

Yes. fort is very common in speech: jeg skjærer fort.
Nuance: raskt can sound a bit more neutral/formal; fort is everyday and slightly more general (“quickly/fast”).

Why is the word order at jeg skjærer and not at skjærer jeg?

Norwegian main clauses are verb-second (V2), but subordinate clauses (like those after at) are not. So you keep Subject–Verb order:

Main clause: Jeg skjærer raskt. (V2)
Sub clause: … at jeg skjærer raskt. (no inversion)

Where would I put negation (ikke) in the at-clause?

In subordinate clauses, ikke comes right after the subject and before most of the verb phrase:

… at jeg ikke skjærer raskt på skjærebrettet.
Compare main clause: Jeg skjærer ikke raskt.

Why is it på skjærebrettet and not i or til?

på means “on” (a surface). You cut on top of a cutting board: på skjærebrettet.

i = “in/inside,” e.g., i skuffen (in the drawer)
til = often “to/for,” not used for surfaces here.

What is the gender and inflection of skjærebrett?

skjærebrett is neuter.

Indefinite singular: et skjærebrett
Definite singular: skjærebrettet (used in the sentence)
Indefinite plural: skjærebrett
Definite plural: skjærebrettene

Why is skjærebrettet written as one word and not with a hyphen?

Norwegian typically writes compound nouns as one word: skjære + brett → skjærebrett (“cutting board”). Hyphens are only used in special cases (clarity, certain names, or to avoid impossible letter clashes), none of which apply here.

How do I pronounce the tricky parts like skj, æ, and kn?

skj- is pronounced like English “sh”: skjære ≈ “SHAIR-eh” (with a long “æ”).
æ is like the “a” in “cat.”
kn- at the start keeps the k: kniv ≈ “k-neev.”
jeg varies by dialect; in much of Eastern Norway it’s like “yai” or “yeh.”
Roughly: Kniven er så skarp at jeg skjærer raskt på skjærebrettet ≈ “KNEE-ven air so skarp aht yai SHARE-eh raskt paw SHARE-eh-brett-et.”

What’s the difference between å skjære, å kutte, and å hakke?

å skjære: to cut/slice with a knife in a controlled motion; also “to slice” when you say å skjære i skiver.
å kutte: to cut (general, everyday, often interchangeable with skjære).
å hakke: to chop (repeated, small pieces), e.g., å hakke løk.
In this sentence, skjærer fits well because you’re cutting on a board.

Why is it Kniven (definite) and not en kniv?

Using the definite form implies a specific knife known from context (the one we’re using/talking about). If you meant any knife in general, you could say En kniv er så skarp at …, but that sounds odd unless you mean “a certain knife I have here.” Usually we go definite when the item is identifiable in the situation.

How does the adjective skarp inflect?

Base: skarp (masc/fem), skarpt (neuter), skarpe (plural/with definite forms)
Comparative: skarper(e)
Superlative: skarpest
Examples: en skarp kniv, et skarpt blad, de skarpe knivene.

Can I move the adverb and say jeg raskt skjærer?

No. In main clauses you keep V2: the finite verb stays second. Say Jeg skjærer raskt, not Jeg raskt skjærer. In the at-clause, the normal order is Subject–Verb–Adverb: … at jeg skjærer raskt …

Does skjære ever mean something else I should be aware of?

Yes:

Reflexive danger: å skjære seg = “to cut oneself.”
Fixed phrases: å skjære opp (cut up), å skjære i (cut into), å skjære ned (cut down).
There’s also a noun ei skjære meaning “a magpie,” but that’s a different word in context.

If I want to say “so sharp that I don’t need much force,” does the negation placement change?

No, same rule: … så skarp at jeg ikke trenger mye kraft.
Negation ikke comes right after the subject in the at-clause.
