Editing Norwegian language (section)

===Particle classes===
Norwegian has five [[closed class]]es without inflection, i.e. [[lexical category|lexical categories]] with grammatical function and a finite number of members that may not be distinguished by morphological criteria. These are [[interjection]]s, [[grammatical conjunction|conjunctions]], [[grammatical conjunction|subjunctions]], [[preposition]]s, and [[adverbs]]. The inclusion of adverbs here requires that traditional adverbs that are inflected in [[Comparison (grammar)|comparison]] be classified as adjectives, as is sometimes done.

==== Adverbs ====
[[Adverb]]s can be formed from [[adjective]]s in Norwegian. English usually creates adverbs from adjectives by the suffix ''-ly'', like the adverb ''beautifully'' from the adjective ''beautiful.'' By comparison, [[North Germanic languages|Scandinavian languages]] usually form adverbs from adjectives by the [[Neuter (grammar)|grammatical neuter]] singular form of the adjective. This is in general true for both Bokmål and Nynorsk.

Example ([[Bokmål]]):

* {{Lang|nb|Han er '''grusom'''}} ('He is '''terrible'''<nowiki/>')
* {{lang|nb|Det er '''grusomt'''}} ('It is '''terrible'''<nowiki/>')
* {{lang|nb|Han er '''grusomt''' treig}} ('He is '''terribly''' slow')

In the third sentence, {{lang|nb|grusomt}} is an adverb. In the first and second sentence {{lang|nb|grusomt}} and {{lang|nb|grusom}} are adjectives and must agree in grammatical gender with the noun.

Another example is the adjective {{lang|no|vakker}} ('beautiful') which exists in both Nynorsk and Bokmål and has the neuter singular form {{lang|nb|vakkert}}.

Example ([[Nynorsk]]):

* {{Lang|nn|Ho er '''vakker'''}} ('She is '''beautiful'''<nowiki/>') 
* {{Lang|nn|Det er '''vakkert'''}} ('It is '''beautiful'''<nowiki/>')
* {{Lang|nn|Ho syng '''vakkert'''}} ('She sings '''beautifully'''<nowiki/>')
