Fejlen

Fejlen is the definite form of the Danish noun fejl, meaning the fault or the error. The word denotes a particular mistake or defect, as opposed to the general concept of error. In use, fejlen refers to a specific malfunction or miscalculation, for example: Fejlen i programmet blev rettet (The error in the program was corrected). The indefinite form is fejl, and the definite plural is fejlene. The singular plural forms follow Danish grammar for en-words.

Etymology and cognates: Fejlen is cognate with Norwegian feil and Swedish fel, reflecting shared North Germanic roots for “fault” or “error.” The term spans everyday language, technical contexts, and formal writing.

Usage and contexts: In computing and software, fejlen often appears in discussions of bugs and debugging, while compounds such as fejlmelding (error report) and fejlfindingsproces (troubleshooting process) are common. In statistics and measurement, målefejl (measurement error) and fejlmargin (margin of error) are standard terms. In everyday Danish, the word can describe a slip, defect, or malfunction in equipment, plans, or procedures, e.g., Det var en lille fejl (That was a small error).

Forms and grammar: The base noun is fejl; the indefinite singular is fejl, the definite singular is fejlen, and the definite plural is fejlene. The word is a common noun and is capitalized only at the beginning of sentences or in titles.
