Questions & Answers about Hun har god samvittighet.
Not necessarily. In Norwegian, especially after å ha, abstract nouns are often used without an article when you are describing a general state or condition.
So Hun har god samvittighet is the normal, idiomatic way to say that she feels morally clear.
Compare:
- Hun har god samvittighet = she has a clear conscience
- Hun har en god samvittighet = grammatical, but less idiomatic and more descriptive
This article-less pattern is common in Norwegian:
- ha dårlig tid
- ha rett
- ha ansvar
- ha god samvittighet
Because adjectives in Norwegian must agree with the noun.
God is used with singular common/feminine nouns.
Godt is used with singular neuter nouns.
Gode is used with plural and often definite forms.
Since samvittighet is not a neuter noun, god is the correct form.
Examples:
- en god stol
- ei god bok
- et godt hus
- gode bøker
So here:
- god samvittighet = correct
- godt samvittighet = incorrect
