What do you mean by a 'language construct'?

I was recently asked this question in an interview, but couldn't answer it. Can anyone shed some light here?

I quote wikipedia:

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. In simpler terms, it is the syntax/way a programming language is written.

as a simple example

in js a method in a class is

class blub {
    myMethod() {
    }
}

in a java like language

public class blub {
    public void myMethod() {}
}

in php

class blub {
    public function myMethod(): void {}
}

in python

class blub:
    def myMethod(self):
        return;

those are for example (I guess some of them are wrong) syntactical visualizations of the same meaning formulated as different "language constructs"

When you're defining a programming language, you've got some basic components that make up the language. You've got functions. You've got operators like + and -. And you've got language constructs, which are the keywords that form the heart of the language and which are used to build other features.

Language constructs are built into the language runtime, and execute incredibly fast.

A programming language probably has iteration constructs (for, while), comparison constructs (if, switch), and other features like "require", "include", "print", or "echo".
