Ubrugelige

Ubrugelige is a Danish adjective meaning unusable or not fit for use. It is used to describe objects, tools, equipment, or even ideas and arguments that cannot function as intended or are beyond repair. The term can apply to physical items, such as machinery that won’t operate, as well as abstract concepts, like an ubrugelig argument that fails to meet the necessary criteria.

Etymology and meaning extend from ubruglig, formed with the prefix u- indicating negation and brug meaning use, combined with the suffix -lig meaning capable or suitable. Thus ubrugelig literally conveys “not usable.” The related forms reflect Danish adjective agreement and inflection.

Grammar and usage: ubrugelig is the base form for singular common gender nouns or masculine nouns, while ubrugeligt is used for neuter singular, and ubrugelige is the plural form used before plural nouns. In predicative position, the adjective agrees with the subject, as in "Genstandene er ubrugelige" (The items are unusable). In attributive position before plural nouns, you would say "ubrugelige genstande" (unusable items). The term is commonly found in technical, industrial, and quality-control contexts, as well as in everyday speech when commenting on failed tools or ineffective methods.

Examples: "Et ubrugeligt værktøj bør kasseres." "Disse ubrugelige maskiner blev taget ud af drift." "Argumenterne blev anset som ubrugelige." See also: unusable, ubrugelighed, reparerbar, kasseret.
