keyrð

Keyrð is a term in the Icelandic language used as a noun to refer to the act, process, or result of driving or operating something. The word is derived from the verb keyra, meaning to drive or operate a vehicle or machine. In everyday speech, keyrð can appear in contexts describing the running or functioning of transport, equipment, or systems. In technical writing, it is used to denote the operation or execution of devices or programs, similar to how English uses operation, run, or runtime, though the exact usage can vary by field.

Etymology and form can be traced to the verb keyra, with keyrð functioning as a nominalized form that marks a state or activity related to driving or operating. The grammatical role of keyrð depends on the sentence and the surrounding inflection, as is common with Icelandic nominalization.

Usage notes indicate that keyrð is most often encountered in manuals, safety guidelines, and technical documentation where the emphasis is on how equipment or vehicles are run or controlled. It may describe conditions during operation, the duration of a run, or the overall functioning of a system. In contrast to broader terms for operation, such as rekstur, keyrð highlights the act of driving or setting an object in motion and is thus more tied to motion or control.
