Questions & Answers about Søsteren min hjelper henne på kjøkkenet.
In Norwegian you have two ways to say “my sister” with a possessive pronoun:
• Before the noun:
min søster
(noun in indefinite form + possessive)
• After the noun:
søsteren min
(noun in definite form + possessive)
You cannot say søster min because when the pronoun follows the noun, the noun must carry the definite ending -en.
Both min søster and søsteren min mean the same, but many speakers find “søsteren min” more colloquial and “min søster” a bit more neutral or bookish.
henne is the object (accusative) form of the third-person singular feminine pronoun. It functions as the direct object of hjelper (“helps”).
• Subject form: hun (“she”)
• Object form: henne (“her”)
Example:
Hun hjelper henne.
(She helps her.)
You can’t use hun here because that would be a subject pronoun in object position.
