There are two ways to create subcategories.

1. Add a category tag to an already existing category page. For example, add the text [[Category:Animals by common name]] to the bottom of the page Category:Apes by common name. Then "Apes by common name" will show up as a category in the list at Category:Animals by common name.
2. If the sub-category page does not already exist, then you have to create it first (see the tip How to create a category). For example, after you create the Category:Apes by common name page, then you click edit and add [[Category:Animals by common name]] to the bottom of it.

You can make Google search Wikipedia by adding this to your Google search: site:en.wikipedia.org.

Examples:

yellow bellied sapsucker site:en.wikipedia.org

"george mason" site:en.wikipedia.org
