lengden

Lengden is the definite form of the Norwegian noun lengde, meaning length. It denotes the measurement of something along its longest dimension or the distance from end to end. In geometry, physics and everyday language, lengden is used to describe how long an object is, often in relation to other dimensions such as bredde (width) and høyde (height or depth). The term is a noun in definite form and is typically used with a context that specifies the object whose length is being described, for example “lengden på bordet” (the length of the table).

Etymology and cognates: Lengden derives from the Old Norse lengð and is cognate with Danish længde and English length. The definite suffix -en marks specificity in Norwegian, as in other definite noun forms.

Measurement and units: Length is measured in the international system of units using meters as the base unit. Common subunits include centimeters and millimeters, while kilometers are used for longer distances. Measuring tools include tape measures (målebånd), rulers (linjal), and calipers. In practice, the length of objects is often expressed numerically, for example 1.5 m or 180 cm.

Context and scope: Length as a dimension is a fundamental concept in mathematics, physics and engineering, representing one of the three spatial dimensions. It is distinct from distance (avstand) in certain contexts and from time (tid) where relevant.
