Negative prefix (u-)

The negative prefix u-

In Danish, you can often form the opposite of an adjective by adding the prefix u-. This works just like the English prefixes un-, in-, im-, or ir-.

For example, retfærdig (fair) becomes uretfærdig (unfair), and rimelig (reasonable) becomes urimelig (unreasonable).

It is unfair and unreasonable that she must work without getting paid.
Det er uretfærdigt og urimeligt at hun skal arbejde uden at få løn.

Evaluating rules and actions

This prefix is highly useful for evaluating situations, rules, or behaviors.

It is illegal and irresponsible to steal.
Det er ulovligt og uansvarligt at stjæle.
Is it illegal, or is it just an unfair rule?
Er det ulovligt, eller er det bare en uretfærdig regel?

Expressing feelings and comfort

You can also use u- to describe physical states, comfort, or emotions. For instance, tålmodig (patient) becomes utålmodig (impatient), and behagelig (comfortable) becomes ubehagelig (uncomfortable).

The man becomes impatient when he has to wait for the bus.
Manden bliver utålmodig når han skal vente på bussen.
The new sofa is impractical and quite uncomfortable to sit in.
Den nye sofa er upraktisk og ret ubehagelig at sidde i.

Official status and validity

In more formal contexts, gyldig (valid) becomes ugyldig (invalid), and afhængig (dependent) becomes uafhængig (independent).

The contract is invalid if they are not independent.
Kontrakten er ugyldig hvis de ikke er uafhængige.
It is the independent expert who calls the decision irresponsible.
Det er den uafhængige ekspert der kalder beslutningen uansvarlig.
