délka

Délka is a Czech noun meaning length or duration. It denotes the extent of something along one dimension or the period of time something lasts. The term is used across science, engineering, and everyday language in neutral, descriptive contexts.

In geometry and physics, délka refers to the distance along a straight line or path, the size of an object in one dimension, or the extent of a figure. In practical use, délka is measured with tools such as a meter stick or tape measure. Common expressions include délka stolu (the length of a table), délka vozidla (the length of a vehicle), or délka trati (the length of a route).

For time, délka expresses duration. Examples include délka filmu (running time), délka cesty (travel duration), or délka života (life length). Temporal délka is determined with clocks or watches and is typically given in seconds, minutes, hours, or longer units as appropriate.

Measurement and units: the SI base unit for length is the metre. Lengths are commonly expressed in metres, centimetres, and millimetres in everyday Czech usage, with kilometres used for longer distances. Precision in measurement depends on the instrument and context, from simple household tasks to scientific applications.

Etymology and cognates: délka is a native Czech term, with related forms in other Slavic languages, such as délka in Slovak and dlougość in Polish, reflecting a common Slavic root for the concept of extent or duration.
