substituovat

Substituovat is a Czech verb meaning to substitute or replace one thing with another, often temporarily or under specific conditions. It is used for people, objects, or expressions and is typically transitive: substituovat někoho nebo něco. In everyday speech it can refer to replacing a person (for example a substitute teacher or substitute player) as well as to replacing an item or an element in a process.

The word is of Latin origin, from substituere, meaning to place in the position of something else. It arrived in Czech through historical contact with other European languages and is now a standard term in formal and technical language.

Substituovat is widely used in various fields. In mathematics and logic, substitution refers to replacing a variable or expression with another equivalent one, often in solving equations or simplifying expressions (substituce). In chemistry, substitution describes the replacement of an atom or hydrogen by another substituent group (substituent) in a molecule. In linguistics and editing, substitution can describe replacing words or forms within a text. In everyday usage, substituting can mean temporarily taking the place of a person or thing in normal duties or functions.

Related forms include substituce (substitution), substituent (chemistry, the group or atom that replaces another), and the adjective substituční (substitutional or pertaining to substitution). The term is considered relatively formal and is often replaced by nahradit or zaměnit in casual speech, but substituovat remains common in technical, academic, and precise contexts.
