Participles are a group of words that belong to two different word classes: verbs and adjectives. They are made from verbs, but are often used as adjectives.

Example from English:
Verbal use: I have spoken (from the verb to speak)
Adjectival use: The spoken word

Example from Norwegian:
Verbal use: Bilen blir reparert
Adjectival use: En reparert bil

Participles are declined like adjectives:

En reparert bil
Den reparerte bilen
Reparerte biler
osv.

Syntactic Issues

In Norwegian, adjectives (incl. participles) can sometimes stand alone:
The green one = den grønne
The repaired one = den reparerte

For example:
Hvilken bil er din? Den ødelagte eller den reparerte?

Example: de ansatte

A commonly used participle is the word ansatt (employee), which is made from the verb å ansette. It follows the regular pattern for participles:

Verbal use:
Jeg blir/er ansatt
Jeg har ansatt (noen)

Adjectival use:
en ansatt (person)
den ansatte (personen)
ansatte (personer)
de ansatte (personene)

Example: Jeg skal snakke med de ansatte.
