varaktigheter

Varaktigheter is the plural form of varaktighet, a Swedish noun that denotes the length of time something lasts. It covers both objective durations that can be measured with clocks and calendars, and subjective durations as experienced by people. The term is used across disciplines and in everyday language to describe how long events, processes or states endure.

In everyday use, varaktighet can refer to the duration of a meeting, a holiday, a power outage, or a project phase. In science and engineering it describes how long a reaction, signal, device, or service remains active. In music and performing arts varaktighet concerns the length of notes, motifs, scenes, or acts; in film and theatre it helps define pacing and structure. In medicine and pharmacology it denotes the period during which a drug or treatment exerts an effect.

Durations are usually expressed in seconds, minutes, hours, or larger units like days or years. There is also a distinction between objective varaktighet (the actual elapsed time) and perceived varaktighet (how long it feels). Cognitive factors such as attention, task demands, and novelty can alter perceived duration without changing the clock time.

Grammar and usage: varaktighet is a feminine noun. The plural is varaktigheter and the definite plural varaktigheterna. It is often modified by adjectives such as lång, kort eller varaktig in compound terms.
