rozsah

Rozsah is a noun used in Czech and Slovak to denote the extent, breadth, or scope of something. It describes how far a thing reaches, how broad its coverage is, or the boundaries within which an action or phenomenon occurs. In everyday language the term appears in phrases such as rozsah práce (scope of work) or rozsah služeb (range of services), signaling the limits or extent of a subject.

In mathematics and related disciplines, the term commonly refers to the range of a function, that is, the set of all possible output values the function can produce. This usage is often stated as rozsah funkce. It is distinct from the domain, which is the set of allowable input values. Beyond pure math, rozsah can describe the permissible or expected interval for measurements, signals, or instrument readings, for example rozsǎh hodnot (range of values) in data analysis or engineering contexts.

In project management and business contexts, rozsah denotes the boundaries of a project or activity—the work that is included and what is excluded. Clear definition of rozsah helps prevent scope creep and informs planning, budgeting, and resource allocation. The term is sometimes contrasted with dosah (reach or impact), which emphasizes the effect or extent of influence rather than the measurable breadth of content or activity.

Overall, Rozsah functions as a flexible term for describing the size, extent, or coverage of a subject across scientific, technical, and everyday language.
