pravidelné

Pravidelné is a Czech adjective form meaning regular, routine, systematic, or occurring at fixed intervals. It is the neuter singular form of the base adjective pravidelný and is used to describe neuter nouns in the nominative or accusative case. The word comes from pravidlo, meaning rule, and conveys the sense that something follows a pattern or standard.

In general usage, pravidelné denotes repetition or consistency over time. Examples include pravidelné cvičení (regular exercise), pravidelné platby (regular payments), and pravidelné intervaly (regular intervals). It is commonly used to describe schedules, habits, or procedures that are carried out in a predictable, repeatable way, such as pravidelné návyky or pravidelné schůzky.

In science and mathematics, pravidelný is also used to describe objects with uniform or symmetric properties, such as pravidelný mnohoúhelník (regular polygon) or pravidelné tvary and vzorce (regular shapes and patterns). The adverb corresponding to pravidelný is pravidelně, meaning regularly or systematically, as in něco dělá pravidelně or pracovat pravidelně.

Pravidelné is contrasted with nepravidelné, which means irregular or non-regular, describing things that do not follow a consistent pattern or schedule. Related forms include pravidelný (masculine singular) and pravidelná (feminine singular), with the form shifting to match gender and number in Czech grammar.
