With possibilities: This is a redirect from a title that potentially could be expanded into a new article or other type of associated page such as a new template. The topic described by this title may be more detailed than is currently provided on the target page or in a section of that page.
When the target page becomes too large, or for any reason a new page would be an improvement, this redirect may be replaced with an article, template or other project page that is carved out of the target page. See also {{R to section}} and use together with this rcat when appropriate.
If the topic of the redirect is not susceptible to expansion, then use other rcats such as {{R to section}} or {{R to list entry}}when appropriate.
Since a new page may be created, links to this redirect should not be replaced with a direct link to the target page. To make redirects to this page, use {{R avoided double redirect}}.
{{R printworthy}} should be used together with this template when applied to a redirect in mainspace.
To a related topic: This is a redirect to an article about a similar topic.
Redirects from related topics are different than redirects from related words, because a related topic is more likely to warrant a full and detailed description in the target article. If this redirect's subject is notable, then also tag it with {{R with possibilities}} and {{R printworthy}}.
From an alternative language: This is a redirect from a page name in German to a page name in English. These words may directly translate or they may be related words, names or phrases.
This redirect leads to its target in accordance with the naming conventions for titles in other languages and can help writing and searches. However, per WP:NOTBROKEN do not replace these redirected links with a piped link.
When appropriate, protection levels are automatically sensed, described and categorized.
