This code should be placed in your child themes functions file and will change the default pagination slug from page to article.
You will also need to re-save your Permalinks to flush the default rewrite rules.
Simply change article in the above code to whatever you want to replace page with.
This solution answers this question from a member of WP Sites:
One thing I noticed with the site I am modifying compared to the new Genesis site is that when you use pagination on the main site you go from www.example.com to www.example.com/latest/1
Using Genesis you go from www.example.com to www.example.com/page/1
Is it possible to modify page to latest?
