Localizing URLs

Hi, I’m creating a WP site in Brazilian Portuguese. I’m using the latest localized version of WP for Brazil but I wanted to ask you a question.

How can I, if possible, localize the URL structure of my site. For example, for the categories page i would have an URL of wwww.blabla.com/archives/category/. How can I localize the URLs so I can have the words “archives” and “category” translated? Can this be done by changing a template somewhere?

This would help me tremendously with SEO for Brazil and URLs would be easier for users to remember.

Any help is appreciated. Thanks!
