Redirect to:

This page is a redirect. The following categories are used to track and monitor this redirect:

From the plural form: This is a redirect from a plural noun to its singular form.
- This redirect link is used for convenience; it is often preferable to add the plural directly after the link (for example, [[link]]s). However, do not replace these redirected links with a simpler link unless the page is updated for another reason (see WP:NOTBROKEN).
- Use this rcat to tag only mainspace redirects; when plural forms are found in other namespaces, use {{R from modification}} instead.

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}}.

When appropriate, protection levels are automatically sensed, described and categorized.
