Rename controller

Hi!

I'm new in oop and ci and there is a point, where i have no idea for a nice solution:

My first project should be available in different languages. But how can i bring the nice URIs to an other language? I think routes are my friends, but is this the way of choice?

I have in german

Code:

/karte/erstellen

This should in english

Code:

/card/create

As i told, i'm new. So what is the finest way to rename my controllers and methods for a new language?

Thanks
