So i pretty much just finally understood the concept of using something like: constint &var
in the parameters of a function. Where it uses the reference to quicken the process, but is not allowed to change the contents
Where this one meshes const and a reference together, are there others like this that are a shortcuts to make unique outcomes? I was looking at trying to get a list of such things.

More specifically - it removes the need to create a copy of the object being passed as a parameter. As well as the performance benefits, it also avoids any side-effects associated with the copy constructor - and allows you to safely pass objects that aren't copyable or haven't had a copy constructor written for them.
oh wow that is complex, thanks for the link
If it helps, I've never had to use the terms "decl-specifier-seq", "cv-qualifier" or "declarator" in nearly 20 years of being a C/C++ developer :) The way the rules work together are, mostly, logical and intuitive. "const" means pretty much the same thing with a reference as it does with anything else, for example. Once you know what "const" means, the way it applies to a reference is pretty intuitive.
