Dusinet var nok.

Dusinet means the dozen.

The basic noun is et dusin = a dozen.
It is a neuter noun, so the definite singular form takes -et:

• et dusin = a dozen
• dusinet = the dozen

So -et is the definite ending, not a separate word.

In Norwegian, the definite article is usually attached to the end of the noun.

So instead of saying something like the dozen, Norwegian normally says:

• dusinet

This is very common in Norwegian:

• en bil = a car

• bilen = the car

• et hus = a house
• huset = the house

So dusinet already includes the meaning of the.

Var is the past tense of å være = to be.

So:

• er = is / am / are
• var = was / were

That means Dusinet var nok is in the past tense:
The dozen was enough.

If you wanted the present tense, you would say:

• Dusinet er nok = The dozen is enough

Here, nok means enough or sufficient.

So the sentence means that the amount referred to by the dozen was sufficient.

A useful thing to know is that nok can also mean probably or I suppose in other contexts. For example:

• Det er nok sant. = That is probably true.

But in Dusinet var nok, the meaning is clearly enough, not probably.

Yes.

• Et dusin var nok = A dozen was enough
• Dusinet var nok = The dozen was enough

The difference is indefinite vs. definite:

• et dusin introduces the quantity more generally
• dusinet refers to a specific dozen, usually one already known from the context

So if you are talking about some particular set of twelve already mentioned, dusinet makes sense.

No, it is very straightforward.

The structure is:

• Dusinet = subject
• var = verb
• nok = predicative complement

So it follows the normal pattern:

subject + verb + complement

This happens to look very similar to English in this sentence.

No, not here.

Nok stays the same:

• Det var nok.
• Pengene var nok.
• Maten var nok.

So unlike many adjectives in Norwegian, nok is often used without changing form in this kind of meaning.

It can be natural, but it depends on context.

Dusinet var nok sounds like you are talking about a specific dozen that has already been identified. For example, maybe someone asked whether twelve eggs would be sufficient, and the answer is:

• Dusinet var nok.

If you are speaking more generally, Et dusin var nok may sound more natural:

• Et dusin var nok. = A dozen was enough.

So the definite form is fine, but it usually needs some context behind it.
