Definition - What does Syntax mean?
In programming, syntax refers to the rules that specify the correct combined sequence of symbols that can be used to form a correctly structured program using a given programming language. Programmers communicate with computers through the correctly structured syntax, semantics and grammar of a programming language.
Techopedia explains Syntax
Programming syntax contains strings similar to words, much like a human language. Correctly formed syntax strings produce syntactically correct sentences within a specified programming language.
Syntax describes how language variables and characters may be combined into strings. Semantics gives meaning to the combined strings, while grammar converts characters into tokens or character strings.
