Questions on the correct (or improved) formulation of Mathematica code to achieve particular results.

Syntax refers to the rules of how to construct well formed Mathematica-code. Syntax is primarily not about the meaning of the code but is about whether Mathematica understands the input or not. Questions about built-in operators and other special characters of Mathematica, argument order for functions and the proper use of functions and symbols should use this tag.

Questions about the syntax highlighter might use the tag . Questions about introducing custom syntax should use the tag . Questions about the handling, removing, generating and passing of symbols (labels for data) should use the tag .
