Den spontane rollefiguren er riktignok enkel, men kroppsspråket virker troverdig.

Because the noun phrase is definite: it means the spontaneous character/figure, not a spontaneous character/figure.

In Norwegian, when you have:

• a definite noun
• plus an adjective before it

you normally use double definiteness:

• a definite article before the adjective: den
• and the noun itself in definite form: rollefiguren

So:

• en spontan rollefigur = a spontaneous character
• den spontane rollefiguren = the spontaneous character

This is a very common pattern in Norwegian.

Because adjectives usually take the ending -e when they come before a definite noun.

Here:

• spontan = basic form
• den spontane rollefiguren = definite phrase, so the adjective becomes spontane

Compare:

• en spontan rollefigur = a spontaneous character
• den spontane rollefiguren = the spontaneous character

So the -e here is not because of plural, but because the noun phrase is definite.

Rollefiguren is a compound noun:

• rolle = role
• figur = figure / character

Together, rollefigur usually means character, especially in a theatrical, fictional, or performed sense.

Then rollefiguren is the definite form:

• rollefigur = a character
• rollefiguren = the character

Norwegian uses compound nouns very freely, so learners often need to get used to long words made from smaller parts.

Riktignok means something like:

• admittedly
• granted
• it is true that
• to be sure

It often introduces a concession: you admit one thing before contrasting it with another.

In this sentence:

• Den spontane rollefiguren er riktignok enkel, men ... means:
• The spontaneous character is admittedly simple, but ...

So the speaker is saying: yes, one part is simple, but there is still something positive to add afterward.

That is normal Norwegian word order.

In a main clause, the finite verb usually comes in second position. Here:

• Den spontane rollefiguren = first element
• er = finite verb in second position
• riktignok comes after the verb

So:

• Den spontane rollefiguren er riktignok enkel

This placement is very natural for sentence adverbs and similar words in Norwegian.

Because it means the body language, not just body language in a more general indefinite sense.

• kroppsspråk = body language
• kroppsspråket = the body language

In this sentence, the speaker is talking about the body language of that specific character/performance, so the definite form sounds natural.

Also note the compound:

• kropp = body
• språk = language
• kroppsspråk = body language

The extra s in the middle is a linking sound often found in compounds.

Both can be possible in Norwegian, but they are not exactly the same.

• er troverdig = is credible / is believable
• virker troverdig = seems / appears believable

Virker is a little softer and more observational. It suggests how something comes across to the viewer or listener, rather than making a completely direct statement.

So:

• kroppsspråket virker troverdig = the body language seems believable / comes across as believable

This is very natural in reviews, descriptions, and analysis.

Because troverdig is used here as a predicative adjective—that means it comes after a verb like er or virker.

Predicative adjectives are often left in their basic form, but with neuter singular subjects they take -t only if the adjective normally does so. In this case, troverdig already has the form used here.

The subject is kroppsspråket, which is neuter singular, but troverdig stays troverdig.

Compare:

• et troverdig kroppsspråk = a believable body language
• kroppsspråket virker troverdig = the body language seems believable

So this form is completely normal.

Men means but and introduces a contrast.

The structure is:

• Den spontane rollefiguren er riktignok enkel
• men kroppsspråket virker troverdig

So the sentence says:

• one thing is a weakness or limitation: the character is simple
• another thing is a strength: the body language is believable

This kind of concession + contrast is very common in Norwegian:

• riktignok ... men ...
• roughly: admittedly ... but ...

Grammatically, spontane modifies rollefiguren, so it describes the character/figure.

But exactly what it means depends on context. It could suggest:

• a character who behaves spontaneously
• a role figure that feels improvised or unplanned
• a performance style that comes across as spontaneous

So the grammar is clear, but the precise nuance depends on the larger context.

The sentence has two main clauses joined by men:

1. Den spontane rollefiguren er riktignok enkel
2. men kroppsspråket virker troverdig

A rough breakdown:

First clause:

• Den spontane rollefiguren = subject
• er = finite verb
• riktignok = sentence adverb
• enkel = subject complement

Second clause:

• kroppsspråket = subject
• virker = finite verb
• troverdig = complement

This is a very standard Norwegian sentence pattern, and it is a good example of normal main-clause word order.
