Skrammen er liten.

Skrammen is the definite singular form of skramme.

A useful mini-paradigm is:

• en skramme = an indefinite singular form
• skrammen = the definite singular form

In Bokmål, skramme is a noun that can often be treated as a feminine noun or as common gender, so skrammen is a normal written form.

Because Norwegian usually puts definiteness on the end of the noun instead of using a separate word like English the.

So:

• skramme = scratch / scrape
• en skramme = a scratch / a scrape
• skrammen = the scratch / the scrape

This ending -en is doing the job that the does in English.

Because liten is the form that matches a singular common-gender noun.

The adjective liten is irregular, and its main forms are:

• liten = singular common gender
• lite = singular neuter
• små = plural
• lille = definite form used before a noun

Since skrammen is singular and treated here as common gender, liten is the right form.

Because lille is normally used when the adjective comes before the noun.

Compare:

• den lille skrammen = the small scratch
• Skrammen er liten = the scratch is small

In Skrammen er liten, the adjective comes after er, so it is a predicative adjective. Predicative adjectives do not usually take the definite form just because the noun is definite.

Yes, that can also be possible in Bokmål if you use feminine forms.

For example:

• ei skramme
• skramma
• lita

So Skramma er lita is a feminine-style version.

Many learners use the common-gender style:

• en skramme
• skrammen
• liten

That is widely accepted and often simpler to learn at first.

The word order is very straightforward:

• Skrammen = subject
• er = verb
• liten = subject complement / predicate adjective

So the pattern is:

subject + verb + adjective

This is similar to English The scratch is small.

Er is the present tense of å være, which means to be.

So here it works just like English is:

• jeg er = I am
• du er = you are
• han er = he is
• skrammen er = the scratch is

A rough English-style approximation is:

SKRAHM-men er LEE-ten

A few pronunciation notes:

• sk in skrammen is a real sk sound, not sh
• a in skrammen is more open than in English cat
• i in liten sounds like a long ee
• the r sound depends on dialect, so different Norwegians may say it a bit differently

The exact pronunciation varies by region, but that approximation will get you close.
