# Using MediaWiki Variables

< MediaWiki Project < Topic:MediaWiki templates
Variables provide useful information about the MediaWiki software that can be used alone or in combinations with other MediaWiki features. Templates use variables for example to adopt to changes in page names or to adopt to changes in the current time, rather than using static text.

### Page variables

Some variables are available which can be used to gain information about a page. They are:
| Variable | Example | Explanation |
| {{NAMESPACE}} | | The current page's namespace. For the main namespace there is no name. |
| {{PAGENAME}} | Using MediaWiki Variables | The current page's name, including all levels (Title/Subtitle), without the namespace name. |
| {{BASEPAGENAME}} | Using MediaWiki Variables | The parent page's name, in namespaces supporting subpages ("Title/Other" for "Title/Other/Subtitle"). |
