Rozruch

Rozruch is a Polish noun meaning the act of starting or initiating something. It has several senses across different domains, ranging from technical ignition to social events. The related verb is uruchomić (to start or launch) and the noun form uruchomienie (start-up).

In mechanical and everyday language, rozruch describes the process of starting a device or engine, the moment when it leaves an idle state and begins operation. This can involve procedures such as preheating, priming, or gradual load application to ensure proper functioning and safety.

In computing, rozruch refers to booting a system—the sequence by which hardware initializes and the operating system loads after power-on or after a reboot.

In economics and industry, the term is used for the ramp-up phase of production or activity, for example after a shutdown, during the launch of a new plant, or at the start of a project. Phrases like rozruch gospodarczy and rozruch produkcyjny are common in discussions of capacity and throughput.

In social and political contexts, rozruch can denote unrest or an uprising, particularly in the plural rozruchy, meaning riots or street disturbances. The word conveys a sense of initiating or rekindling activity that moves systems, processes, or publics from one state to another.

Etymology traces rozruch to the prefix roz- plus ruch (movement), underscoring the idea of putting something into motion. The term is widely used in technical, economic, and social discourse, with meaning shaped by context.
