výrazy

Výrazy is a term used in Czech and Slovak to denote expressions, phrases, terms, or signs. It is a broad concept that appears across several domains, including language, mathematics, and computer science, as well as in everyday speech to refer to the way something is conveyed or manifested.

In linguistics and everyday use, výrazy refer to units of language that convey meaning. They can be single words or multiword phrases, including idioms and fixed expressions. Some expressions carry a literal meaning, while others convey figurative sense or cultural nuance.

In mathematics, a výraz (expression) is a syntactic combination of numbers, symbols, variables, and operators that can be evaluated to a value. Examples include 3a + 5, (x − 2)y, or sin(θ). Expressions can often be simplified or transformed, but they are distinguished from equations, which include an equality sign, and from formulas, which express general rules.

In computer science and programming, an expression is a construct that computes to a value. This includes arithmetic expressions like a + b, logical expressions like flag && isReady, and more complex forms such as function calls. The evaluation result may depend on the program state, and expressions are foundational to defining statements and control flow.

Other uses of výrazy include referring to facial expressions or outward appearances, as a way to manifest emotions, attitudes, or conditions.
