The programming syntax is the set of rules that regulate and coordinate the different variables and their association.
In language, syntax is the set of combinatorial rules and laws that structure the construction of sentences and texts. The syntax refers to the inclusion of subject and predicate and the role of words in relation to each other. In computer science, the syntax comprises an equivalent concept.
For computing, the syntax is a group of rules that work by governing the linking of the different variables that make up the operating instructions.
In programming, there are three relevant variables: syntax, semantics, and hierarchy.
The first has to do with the fact that a programming language of a software or application can be understood as a series of particular characters in combination. The syntax comes to be composed of the rules that determine if said combination or "string" is valid or not and, therefore, operative.
Within that syntax you can also find grammars and regular expressions. This means that there are common paths that are often used by programmers when working with variables and characters.
Common terms when talking about programming syntax are: identifiers, reserved words, literals or constants, and special symbols.
It is common that in certain applications or programs we receive an error classified by the same program as "Syntax error"; this refers to a failure in the programming of said software or in the combination of the variables in its use.
As users, when executing an operation or command, we would probably see a button, menu or option. However, in the programming code or 'backend' of the program or application, you would see a particular character association syntax.
