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 a programming language.

The term "language construct" is often used as a synonym for control structure, and should not be confused with a function.

Examples of language constructs

In PHP print is a language construct. [1]

<?php
print 'Hello world';
?>

is the same as:

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