How can I alias `…` to `../..` in Bash?

How can I alias ... to ../.. in Bash?

I am aware that other answers allow alias '...'='cd ../..' but I’d like to be able to address the directory two levels up with other commands, allowing for:

cd ...
ls ...
realpath ...

I have tried alias '...'='../..' but when trying to use this I get the following:

$ alias '...'='../..'
$ type ...
... is aliased to '../..'
$ cd ...
bash: cd: ...: No such file or directory

I’m aware aliases are intended for use with commands. Is there a way to achieve the same functionality for a path in this case?
