What is the meaning the $ special character?

Hello... and thank you in advanced for any help anyone can offer me

I'm hoping someone can explain what the leading $ is/means (i.e. $PS1, $HOME, etc).... I was having a discussion with someone and was trying to explain it... Which I felt like I came up kind of short with how well I did it.

I understand it's a special character and how to use it if I want to see the value of a variable or if I want to see the status of a command... I'm just unsure what kind of special character its categorized as or the definition of it's exact function.

I got home and googled it... I found plenty of explanations on how to use it but didn't find an adequate explanation of what it is and it's definition. It seems like every special character is well documented except the $... Could someone explain to me how it's categorized and it's extract definition?

Once again... thanks for reading this and any help anyone can offer
