Category:Fundamental

This is a "root" category, a top-level place to start when browsing Wikipedia categories for articles. This is the top level in terms of encyclopedia article function and content.

An alternative root category, based on a somewhat more detailed initial classification, is Category:Main topic classifications.

The top level of Wikipedia's overall category system, containing both articles and other Wikipedia project pages, is Category:Contents.
