Ekspresion

Ekspresion is a cross-disciplinary term used to denote expression—the act of representing a value, idea, emotion, or meaning through symbols, signs, or actions. The spelling ekspre­sion appears in several languages as a cognate of the English expression, though local variants such as ekspresi are common in some contexts.

In mathematics and related fields, an ekspresion is a finite combination of numbers, variables, and operators meant to be evaluated to a value. Examples include 3x + 2 and sqrt(a^2 + b^2). An ekspresion is not a statement and does not assert truth; it yields a value when its variables are given specific inputs.

In computer science, an ekspresion (expression) is any code fragment that evaluates to a value. It may include literals, variables, operators, and function calls. Expressions can sometimes have side effects depending on the language; they are distinguished from statements, which perform actions without necessarily producing a value.

In linguistics and everyday use, ekspresion covers expressions of meaning or emotion, such as idiomatic expressions, facial expressions, or artistic expressions used to convey sentiment, intent, or character.

Because the term spans mathematics, computing, language, and art, ekspresion is a broad concept centered on representing value, meaning, or emotion through a form, symbol, or action.
