| Jan 28, 2023 at 0:10 | comment | added | lericr | I’m voting to close this question because I believe that it has the potential to be confusing, because it's anchored to what seems to be a mistaken understanding of the evaluation process and the notion of "expression". | |
| Jan 28, 2023 at 0:07 | comment | added | lericr | Yeah, at this point I think this post and my attempts to answer are probably more confusing that enlightening. I'm voting to close also. | |

| Jan 27, 2023 at 17:30 | comment | added | zbjoko | I now know that you can use these objects with annotated Names in two ways: as Variables or as functions. You have beforehand define OverHat[x_]:= ... | |

Okay, well if you did something like SymbolName["Overscript[x,^]"], then that message makes sense. Any expression of the form SomeSymbol[<...stuff...>] is a headed expression and so not a symbol by definition (by the basic syntax of Mathematica), so SymbolName cannot give you the name, because you didn't give it a symbol.

| Jan 27, 2023 at 17:27 | comment | added | zbjoko | Yes, I use this function to get that message. | |

And is your question about symbols per se, or is it about assigning a value to things like OverHat[x]?

Can you clarify what you did to get that message? Were you trying to use the literal built-in function SymbolName?
