Syntax error - GCSE Computer Science Definition

A syntax error is a type of mistake in a computer program's code that happens when the rules of the programming language are not followed correctly. Think of it like writing a sentence that does not follow the rules of grammar, like "The cat run fastly." In a computer program, even a small syntax error, like a missing bracket or a misspelled word, can stop the program from working properly or running at all. Syntax errors are often spotted by the computer as soon as you try to run the program, and fixing them is usually the first step in making sure your code works correctly.
