Language construct

{{Short description|Syntactically valid part of a program formed from lexical tokens}}

In computer programming, a language construct is "a syntactically allowable part of a program that may be formed from one or more lexical tokens in accordance with the rules of the programming language", as defined by in the ISO/IEC 2382 standard (ISO/IEC JTC 1).{{cite web |title=ISO/IEC 2382, Information technology — Vocabulary |url=https://www.iso.org/obp/ui/#iso:std:iso-iec:2382:ed-1:v1:en}}

A term is defined as a "linguistic construct in a conceptual schema language that refers to an entity".

While the terms "language construct" and "control structure" are often used synonymously, there are additional types of logical constructs within a computer program, including variables, expressions, functions, or modules.

Control flow statements (such as conditionals, foreach loops, while loops, etc) are language constructs, not functions. So while (true) is a language construct, while add(10) is a function call.
