fejler

Fejler is the Danish present tense form of the verb fejle, meaning to fail, to make an error, or to malfunction. It describes errors committed by people or failures in systems and devices. The form is used with third-person singular subjects. Example: Hvis maskinen fejler, skal den genstartes.

The basic forms of the verb include fejlede (simple past) and har fejlet (present perfect). The word’s etymology traces to older North Germanic roots and is related to notions of fault or error.

In Norwegian Bokmål, the cognate verb is feile, with present tense feiler. Danish and Norwegian share a Germanic heritage, though spelling and usage differ between the languages.

Used neutrally, fejler can describe both human mistakes and technical faults, depending on context. It is a common term in everyday Danish as well as in technical and educational discourse.
