Wikipedia:Subpage

Making a new [[link]] that begins with a / (slash) is the common way to start a subpage. The page to which this link points is considered "subordinate" to its host page, and is titled and linked as [[Parentpage/Subpage]]. It is possible to create a subpage of a subpage (or a sub-subpage). At the top of each subpage or sub-subpage, you can find a backlink (a.k.a. breadcrumb) to the higher levels of the page.

The "All pages with prefix" report from shows subpages.

The "Search" report from similarly uses a prefix search parameter to show subpages. For example:   .  

Comparing the two:

To keep an active display of subpages, see {{}}. To keep a link to an "All pages..." report, use {{}} or [[Special:PrefixIndex]]. To keep a link to a "Search" report, use a {{}}.

Outside of a single page name, there is no direct method for finding subpages. Standard subpagenames are searchable using the intitle parameter.

There are .

All other namespaces allow subpages. You can create a subpage simply by linking to the name of the subpage, prefixed with a slash (e.g. [[/Archive]]).

Some topics have a slash in the name, and should be named accordingly—e.g. GNU/Linux naming controversy or OS/2. Care should be taken with the corresponding talk pages, though, as subpages are enabled in talk space—for example, is treated by the software as a subpage of .

Note that older discussions of subpages are generally concerned with articles named as subpages of other articles; this is no longer done.
