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 onlymainspace redirects; when plural forms are found in other namespaces, use {{R from modification}}instead.
From a subtopic: This is a redirect from a subtopic of the target article or section.
To a section: This is a redirect from a topic that does not have its own page to a section of a page on the subject. For redirects to embedded anchors on a page, use {{R to anchor}}instead.
