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).^[1] A term is defined as a "linguistic construct in a conceptual schema language that refers to an entity".^[1]

Although the term "language construct" may often used as a synonym for control structure, other kinds of logical constructs of a computer program include 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.

Examples of language constructs[edit]

In PHP print is a language construct.^[2]

<?php print 'Hello world'; ?> 

is the same as:

<?php print('Hello world'); ?> 

In Java a class is written in this format:

public class MyClass {     //Code . . . . . . } 

In C++ a class is written in this format:

class MyCPlusPlusClass {     //Code . . . . };
