  • This is a redirect from a plural noun to its singular form. You may use the aliased template {{R to singular}} to accomplish the same end.
    • This redirect link is used for convenience, usually for plurals that do not follow simple conventions. In many cases, it is 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 mainspace redirects; when plural forms are found in other namespaces, use {{R mod}} instead. For more information, follow the category link.
